117-623: Andhra Pradesh State Road Transport Corporation (abbreviated as APSRTC ), officially Andhra Pradesh Raastra Roadu Ravaana Samstha , is the state-owned road transport corporation in the Indian state of Andhra Pradesh . Its headquarters is located at NTR Administrative Block of RTC House in Pandit Nehru bus station of Vijayawada . Many other Indian metros & towns in Telangana , Tamil Nadu , Karnataka , Odisha and Chhattisgarh are also linked with

234-587: A free port . To avoid accidents caused by fatigue, truckers have to adhere to strict rules for drive time and required rest periods. In the United States and Canada, these regulations are known as hours of service , and in the European Union as drivers working hours . One such regulation is the Hours of Work and Rest Periods (Road Transport) Convention, 1979 . Tachographs or Electronic on-board recorders record

351-658: A saddle or in a harness between the ages of two and four. They reach full adult development by age five, and have an average lifespan of between 25 and 30 years. Horse breeds are loosely divided into three categories based on general temperament: spirited "hot bloods" with speed and endurance; "cold bloods", such as draft horses and some ponies , suitable for slow, heavy work; and " warmbloods ", developed from crosses between hot bloods and cold bloods, often focusing on creating breeds for specific riding purposes, particularly in Europe. There are more than 300 breeds of horse in

468-944: A van or pickup truck may be used. For large shipments even if less than a full truckload a truck is more appropriate. (Also see Trucking and Hauling below). In some countries cargo is transported by road in horse-drawn carriages, donkey carts or other non-motorized mode. Delivery services are sometimes considered a separate category from cargo transport. In many places, fast food is transported on roads by various types of vehicles . For inner city delivery of small packages and documents bike couriers are quite common. People are transported on roads. Special modes of individual transport by road such as cycle rickshaws may also be locally available. There are also specialist modes of road transport for particular situations, such as ambulances. The first methods of road transport were horses , oxen or even humans carrying goods over dirt tracks that often followed game trail . The Persians later built

585-454: A clear hierarchy of rank, led by a dominant individual, usually a mare. They are also social creatures that are able to form companionship attachments to their own species and to other animals, including humans. They communicate in various ways, including vocalizations such as nickering or whinnying, mutual grooming , and body language . Many horses will become difficult to manage if they are isolated, but with training, horses can learn to accept

702-677: A cloverleaf and trumpet interchange when it opened in 1937 and until the Second World War boasted the longest illuminated stretch of roadway built. A decade later, the first section of Highway 401 was opened, based on earlier designs. It has since become North America's busiest highway. The word freeway was first used in February 1930 by Edward M. Bassett . Bassett argued that roads should be classified into three basic types: highways, parkways , and freeways. In Bassett's zoning and property law -based system, abutting property owners have

819-428: A constant eye out for danger. Unlike humans, horses do not sleep in a solid, unbroken period of time, but take many short periods of rest. Horses spend four to fifteen hours a day in standing rest, and from a few minutes to several hours lying down. Total sleep time in a 24-hour period may range from several minutes to a couple of hours, mostly in short intervals of about 15 minutes each. The average sleep time of

936-597: A continental-sized network meant to connect every population center of 50,000 people or more. By 1956, most limited access highways in the eastern United States were toll roads. In that year, the Federal Aid Highway Act of 1956 was passed, funding non-toll roads with 90% federal dollars and 10% state match, giving little incentive for states to expand their turnpike system. Funding rules initially restricted collections of tolls on newly funded roadways, bridges, and tunnels. In some situations, expansion or rebuilding of

1053-519: A country, and may include federal standards. The United States uses FMCSA federal standards that include bridge law formulas . Many states, not on the national road system, use their own road and bridge standards. Enforcement scales may include portable scales, scale houses with low speed scales or weigh-in-motion (WIM) scales. The European Union uses the International Recommendation , OIML R 134-2 (2009). The process may involve

1170-520: A county. In 18th century West Africa , road transport throughout the Ashanti Empire was maintained via a network of well-kept roads that connected the Ashanti capital with territories within its jurisdiction and influence. After significant road construction undertaken by the kingdom of Dahomey , toll roads were established with the function of collecting yearly taxes based on the goods carried by

1287-473: A full 60 calendar months (five years) old. The horse skeleton averages 205 bones. A significant difference between the horse skeleton and that of a human is the lack of a collarbone —the horse's forelimbs are attached to the spinal column by a powerful set of muscles, tendons, and ligaments that attach the shoulder blade to the torso. The horse's four legs and hooves are also unique structures. Their leg bones are proportioned differently from those of

1404-433: A given lane and median barriers can prevent left turns and even U-turns. Early toll roads were usually built by private companies under a government franchise. They typically paralleled or replaced routes already with some volume of commerce, hoping the improved road would divert enough traffic to make the enterprise profitable. Plank roads were particularly attractive as they greatly reduced rolling resistance and mitigated

1521-478: A good sense of balance and a strong fight-or-flight response . Related to this need to flee from predators in the wild is an unusual trait: horses are able to sleep both standing up and lying down, with younger horses tending to sleep significantly more than adults. Female horses, called mares , carry their young for approximately 11 months and a young horse, called a foal , can stand and run shortly following birth. Most domesticated horses begin training under

1638-630: A high level of intelligence that may or may not be used to cooperate with human handlers. Small size, by itself, is not an exclusive determinant. For example, the Shetland pony which averages 10 hands (40 inches, 102 cm), is considered a pony. Conversely, breeds such as the Falabella and other miniature horses , which can be no taller than 76 centimetres; 7.2 hands (30 in), are classified by their registries as very small horses, not ponies. Horses have 64 chromosomes . The horse genome

1755-439: A higher rate of gastric ulcers than horses listening to music, and racehorses stabled where a radio was played had a higher overall rate of ulceration than horses stabled where there was no radio playing. Horses have a great sense of balance, due partly to their ability to feel their footing and partly to highly developed proprioception —the unconscious sense of where the body and limbs are at all times. A horse's sense of touch

1872-413: A human as a companion, and thus be comfortable away from other horses. However, when confined with insufficient companionship, exercise, or stimulation, individuals may develop stable vices , an assortment of bad habits, mostly stereotypies of psychological origin, that include wood chewing, wall kicking, "weaving" (rocking back and forth), and other problems. Studies have indicated that horses perform

1989-420: A human. For example, the body part that is called a horse's "knee" is actually made up of the carpal bones that correspond to the human wrist . Similarly, the hock contains bones equivalent to those in the human ankle and heel . The lower leg bones of a horse correspond to the bones of the human hand or foot, and the fetlock (incorrectly called the "ankle") is actually the proximal sesamoid bones between

2106-761: A licence, which usually requires them to pass an exam (e.g. in the EU). They have to make sure they affix proper labels for the respective hazard(s) to their vehicle. Liquid goods are transported by road in tank trucks (in American English) or tanker lorries (in British English) (also road-tankers) or special tank containers for intermodal transport . For transportation of live animals special requirements have to be met in many countries to prevent cruelty to animals (see animal rights ). For fresh and frozen goods refrigerator trucks or reefers are used. Some loads are weighed at

2223-526: A major component of grass, through the process of hindgut fermentation . Cellulose fermentation by symbiotic bacteria and other microbes occurs in the cecum and the large intestine . Horses cannot vomit , so digestion problems can quickly cause colic , a leading cause of death. Although horses do not have a gallbladder , they tolerate high amounts of fat in their diet. The horses' senses are based on their status as prey animals , where they must be aware of their surroundings at all times. The equine eye

2340-427: A margin of side clearance, a refuge for incapacitated vehicles, an emergency lane, and parking space. They also serve a design purpose, and that is to prevent water from percolating into the soil near the main pavement's edge. Shoulder pavement is designed to a lower standard than the pavement in the traveled way and won't hold up as well to traffic, so driving on the shoulder is generally prohibited. Pavement technology

2457-560: A network of Royal Roads across their empire. With the advent of the Roman Empire , there was a need for armies to be able to travel quickly from one region to another, and the roads that existed were often muddy, which greatly delayed the movement of large masses of troops . To resolve this issue, the Romans built solid and lasting roads. The Roman roads used deep roadbeds of crushed stone as an underlying layer to ensure that they kept dry, as

2574-797: A number of cognitive tasks on a daily basis, meeting mental challenges that include food procurement and identification of individuals within a social system . They also have good spatial discrimination abilities. They are naturally curious and apt to investigate things they have not seen before. Studies have assessed equine intelligence in areas such as problem solving , speed of learning, and memory . Horses excel at simple learning, but also are able to use more advanced cognitive abilities that involve categorization and concept learning . They can learn using habituation , desensitization , classical conditioning , and operant conditioning , and positive and negative reinforcement . One study has indicated that horses can differentiate between "more or less" if

2691-494: A particular section of roadway, and tolls were collected from users to finance the enterprise. The enterprise was usually named to indicate the locale of its roadway, often including the name of one of both of the termini. The word turnpike came into common use in the names of these roadways and companies, and is essentially used interchangeably with toll road in current terminology. In the United States , toll roads began with

2808-589: A precocial species, and foals are capable of standing and running within a short time following birth. Foals are usually born in the spring. The estrous cycle of a mare occurs roughly every 19–22 days and occurs from early spring into autumn. Most mares enter an anestrus period during the winter and thus do not cycle in this period. Foals are generally weaned from their mothers between four and six months of age. Horses, particularly colts, are sometimes physically capable of reproduction at about 18 months, but domesticated horses are rarely allowed to breed before

2925-477: A predominantly white hair coat and pink skin, a fairly rare occurrence. Different and unrelated genetic factors can produce white coat colors in horses, including several different alleles of dominant white and the sabino-1 gene . However, there are no " albino " horses, defined as having both pink skin and red eyes. Gestation lasts approximately 340 days, with an average range 320–370 days, and usually results in one foal ; twins are rare. Horses are

3042-457: A rise of three inches from the edges to the center. Cambering and elevation of the road above the water table enabled rainwater to run off into ditches on either side. Size of stones was central to the McAdam's road building theory. The lower 200-millimetre (8 in) road thickness was restricted to stones no larger than 75 millimetres (3.0 in). The upper 50-millimetre (2 in) layer of stones

3159-481: A scale house and low-speed scales or higher-speed WIM road or bridge scales with the goal of public safety, as well as road and bridge safety, according to the Bridges Act . Today, roadways are primarily asphalt or concrete . Both are based on McAdam's concept of stone aggregate in a binder, asphalt cement or Portland cement respectively. Asphalt is known as a flexible pavement , one which slowly will "flow" under

3276-534: A section of the London- Chester road between Foothill and Stony Stafford . The basic principle was that the trustees would manage resources from the several parishes through which the highway passed, augment this with tolls from users from outside the parishes and apply the whole to the maintenance of the main highway. This became the pattern for the turnpiking of a growing number of highways, sought by those who wished to improve flow of commerce through their part of

3393-495: A separate entity from 3 June 2015. APSRTC is working from Vijayawada (Pandit Nehru Bus Stand) as Headquarters for the state of Andhra Pradesh. APSRTC has a target to convert its entire bus fleet to electric buses - using both battery electric buses and fuel cell buses - by the year 2029. The organisation is divided into four zones with twelve Regional Managers. It has a total of 11,678 buses (government-owned 8964; hire on rental 2714) operating in 44.15 lakh kilometers and has

3510-618: A toll facility using Interstate Highway Program funding resulted in the removal of existing tolls. This occurred in Virginia on Interstate 64 at the Hampton Roads Bridge-Tunnel when a second parallel roadway to the regional 1958 bridge-tunnel was completed in 1976. Since the completion of the initial portion of the Interstate Highway System, regulations were changed, and portions of toll facilities have been added to

3627-867: A total of 426 bus stations and 129 bus depots. From 30 January 2019, all the APSRTC vehicles in the state are registered as AP–39 , followed by "Z" and four digits. The Andhra Pradesh State Road Transport Corporation operates various services both for urban transport as well as intercity and village transport, and cargo services. Various bus services operated by the Andhra Pradesh State Road Transport Corporation. These services offered by APSRTC to carry parcels, couriers, goods and bulk materials. These services can be booked and utilised by public for shifting their goods and valuables. Every bus depot in APSRTC having one DGT Bus. These Services having door step cargo delivery facility. As of March 2019,

3744-505: Is adequate healthy food. All horses move naturally with four basic gaits : Besides these basic gaits, some horses perform a two-beat pace , instead of the trot. There also are several four-beat ' ambling ' gaits that are approximately the speed of a trot or pace, though smoother to ride. These include the lateral rack , running walk , and tölt as well as the diagonal fox trot . Ambling gaits are often genetic in some breeds, known collectively as gaited horses . These horses replace

3861-416: Is in the nostrils and nasal cavity, which analyze a wide range of odors. The second, located under the nasal cavity, are the vomeronasal organs , also called Jacobson's organs. These have a separate nerve pathway to the brain and appear to primarily analyze pheromones . A horse's hearing is good, and the pinna of each ear can rotate up to 180°, giving the potential for 360° hearing without having to move

3978-410: Is measured at the highest point of the withers , where the neck meets the back . This point is used because it is a stable point of the anatomy, unlike the head or neck, which move up and down in relation to the body of the horse. In English-speaking countries, the height of horses is often stated in units of hands and inches: one hand is equal to 4 inches (101.6 mm). The height is expressed as

4095-417: Is one of the largest of any land mammal. Horses are lateral-eyed, meaning that their eyes are positioned on the sides of their heads. This means that horses have a range of vision of more than 350°, with approximately 65° of this being binocular vision and the remaining 285° monocular vision . Horses have excellent day and night vision , but they have two-color, or dichromatic vision ; their color vision

4212-535: Is orderly and safe. Two hundred years ago these devices were signs, nearly all informal. In the late 19th century signals began to appear in the biggest cities at a few highly congested intersections. They were manually operated, and consisted of semaphores, flags or paddles , or in some cases colored electric lights, all modeled on railroad signals. In the 20th century signals were automated, at first with electromechanical devices and later with computers. Signals can be quite sophisticated: with vehicle sensors embedded in

4329-426: Is somewhat like red-green color blindness in humans, where certain colors, especially red and related colors, appear as a shade of green. Their sense of smell , while much better than that of humans, is not quite as good as that of a dog. It is believed to play a key role in the social interactions of horses as well as detecting other key scents in the environment. Horses have two olfactory centers. The first system

4446-410: Is still evolving, albeit in not easily noticed increments. For instance, chemical additives in the pavement mix make the pavement more weather resistant, grooving and other surface treatments improve resistance to skidding and hydroplaning , and joint seals which were once tar are now made of low maintenance neoprene. Nearly all roadways are built with devices meant to control traffic . Most notable to

4563-467: Is summed up by the traditional adage, "no foot, no horse". The horse hoof begins with the distal phalanges , the equivalent of the human fingertip or tip of the toe, surrounded by cartilage and other specialized, blood-rich soft tissues such as the laminae . The exterior hoof wall and horn of the sole is made of keratin , the same material as a human fingernail . The result is that a horse, weighing on average 500 kilograms (1,100 lb), travels on

4680-476: Is the layer or successive layers of stone, gravel and sand supporting the pavement. It is needed to spread out the slab load bearing on the underlying soil and to conduct away any water getting under the slabs. Water will undermine a pavement over time, so much of pavement and pavement joint design are meant to minimize the amount of water getting and staying under the slabs. Shoulders are also an integral part of highway design. They are multipurpose; they can provide

4797-598: Is usually considered to be a horse and one less than 14.2 hands (58 inches, 147 cm) a pony, but there are many exceptions to the traditional standard. In Australia, ponies are considered to be those under 14 hands (56 inches, 142 cm). For competition in the Western division of the United States Equestrian Federation , the cutoff is 14.1 hands (57 inches, 145 cm). The International Federation for Equestrian Sports ,

4914-520: Is well-developed. The most sensitive areas are around the eyes, ears, and nose. Horses are able to sense contact as subtle as an insect landing anywhere on the body. Horses have an advanced sense of taste, which allows them to sort through fodder and choose what they would most like to eat, and their prehensile lips can easily sort even small grains. Horses generally will not eat poisonous plants, however, there are exceptions; horses will occasionally eat toxic amounts of poisonous plants even when there

5031-545: The Bonn-Cologne Autobahn began in 1929 and was opened in 1932 by Konrad Adenauer , then the mayor of Cologne . In Canada, the first precursor with semi-controlled access was The Middle Road between Hamilton and Toronto , which featured a median divider between opposing traffic flow, as well as the nation's first cloverleaf interchange . This highway developed into the Queen Elizabeth Way , which featured

5148-702: The Lancaster Turnpike in the 1790s, within Pennsylvania , connecting Philadelphia and Lancaster . In the state of New York , the Great Western Turnpike was started in Albany in 1799 and eventually extended, by several alternate routes, to near what is now Syracuse, New York . Toll roads peaked in the mid 19th century, and by the turn of the twentieth century most toll roads were taken over by state highway departments. The demise of this early toll road era

5265-484: The Morgan horse . Horses are able to sleep both standing up and lying down. In an adaptation from life in the wild, horses are able to enter light sleep by using a " stay apparatus " in their legs, allowing them to doze without collapsing. Horses sleep better when in groups because some animals will sleep while others stand guard to watch for predators. A horse kept alone will not sleep well because its instincts are to keep

5382-620: The Pennsylvania Turnpike , toll roads saw a resurgence, this time to fund limited access highways. In the late 1940s and early 1950s, after World War II interrupted the evolution of the highway, the US resumed building toll roads. They were to still higher standards and one road, the New York State Thruway , had standards that became the prototype for the U.S. Interstate Highway System . Several other major toll-roads which connected with

5499-472: The Trakehner or Hanoverian , developed when European carriage and war horses were crossed with Arabians or Thoroughbreds, producing a riding horse with more refinement than a draft horse, but greater size and milder temperament than a lighter breed. Certain pony breeds with warmblood characteristics have been developed for smaller riders. Warmbloods are considered a "light horse" or "riding horse". Today,

5616-406: The cannon bones (a single equivalent to the human metacarpal or metatarsal bones ) and the proximal phalanges , located where one finds the "knuckles" of a human. A horse also has no muscles in its legs below the knees and hocks, only skin, hair, bone, tendons , ligaments , cartilage , and the assorted specialized tissues that make up the hoof . The critical importance of the feet and legs

5733-460: The gene controlled by the Melanocortin 1 receptor , also known as the "extension gene" or "red factor". Its recessive form is "red" (chestnut) and its dominant form is black. Additional genes control suppression of black color to point coloration that results in a bay , spotting patterns such as pinto or leopard , dilution genes such as palomino or dun , as well as greying , and all

5850-577: The "cold-bloods", such as most draft breeds , are quieter and calmer. Sometimes "hot-bloods" are classified as "light horses" or "riding horses", with the "cold-bloods" classified as "draft horses" or "work horses". "Hot blooded" breeds include " oriental horses " such as the Akhal-Teke , Arabian horse , Barb , and now-extinct Turkoman horse , as well as the Thoroughbred , a breed developed in England from

5967-478: The 18th century. Starting in the early 18th century, the British Parliament began to pass a series of acts that gave the local justices powers to erect toll-gates on the roads, in exchange for professional upkeep. The toll-gate erected at Wade's Mill became the first effective toll-gate in England. The first scheme that had trustees who were not justices was established through a turnpike act in 1707, for

6084-449: The 1920s limited access highways appeared. Their main characteristics were dual roadways with access points limited to (but not always) grade-separated interchanges. Their dual roadways allowed high volumes of traffic , the need for no or few traffic lights along with relatively gentle grades and curves allowed higher speeds. The first limited access highways were Parkways , so called because of their often park-like landscaping and, in

6201-406: The APSRTC services. APSRTC was formed on 11 January 1958 as per "Road Transport Corporations Act 1950". Earlier, it was a part of Nizam State Rail and Road Transport Department , a wing of Nizam State Railway in the erstwhile Hyderabad State . Consequent upon bifurcation of Andhra Pradesh state into Telangana and residual Andhra Pradesh, Telangana State Road Transport Corporation is operated as

6318-540: The French road engineer Pierre-Marie-Jérôme Trésaguet . The first professional road builder to emerge during the Industrial Revolution was John Metcalf , who constructed about 180 miles (290 km) of turnpike road , mainly in the north of England, from 1765. He believed a good road should have good foundations, be well drained and have a smooth convex surface to allow rainwater to drain quickly into ditches at

6435-748: The Pennsylvania Turnpike were established before the creation of the Interstate Highway System. These were the Indiana Toll Road , Ohio Turnpike , and New Jersey Turnpike . In the United States, beginning in 1956, Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly called the Interstate Highway System was built. It uses 12 foot (3.65m) lanes, wide medians , a maximum of 4% grade , and full access control, though many sections don't meet these standards due to older construction or constraints. This system created

6552-624: The Southern Hemisphere. The exception is in endurance riding , where the minimum age to compete is based on the animal's actual calendar age. The following terminology is used to describe horses of various ages: In horse racing , these definitions may differ: For example, in the British Isles, Thoroughbred horse racing defines colts and fillies as less than five years old. However, Australian Thoroughbred racing defines colts and fillies as less than four years old. The height of horses

6669-474: The United States and Australia in the 1820s and in Europe in the 1830s and 1840s. Macadam roads were adequate for use by horses and carriages or coaches, but they were very dusty and subject to erosion with heavy rain. The Good Roads Movement occurred in the United States between the late 1870s and the 1920s. Advocates for improved roads led by bicyclists turned local agitation into a national political movement. Outside cities, roads were dirt or gravel; mud in

6786-456: The age of three, especially females. Horses four years old are considered mature, although the skeleton normally continues to develop until the age of six; maturation also depends on the horse's size, breed, sex, and quality of care. Larger horses have larger bones; therefore, not only do the bones take longer to form bone tissue , but the epiphyseal plates are larger and take longer to convert from cartilage to bone. These plates convert after

6903-562: The building of roads by improving the selection of stone based on thickness, taking into account traffic, alignment and slopes. During his later years, Telford was responsible for rebuilding sections of the London to Holyhead road , a task completed by his assistant of ten years, John MacNeill . It was another Scottish engineer, John Loudon McAdam , who designed the first modern roads. He developed an inexpensive paving material of soil and stone aggregate (known as macadam ). His road building method

7020-727: The calm, patient temperament needed to pull a plow or a heavy carriage full of people. They are sometimes nicknamed "gentle giants". Well-known draft breeds include the Belgian and the Clydesdale . Some, like the Percheron , are lighter and livelier, developed to pull carriages or to plow large fields in drier climates. Others, such as the Shire , are slower and more powerful, bred to plow fields with heavy, clay-based soils. The cold-blooded group also includes some pony breeds. " Warmblood " breeds, such as

7137-603: The client – or through freight carriers or shipping agents. Some big companies (e.g. grocery store chains) operate their own internal trucking operations. The market size for general freight trucking was nearly $ 125 billion in 2010. In the U.S. many truckers own their truck (rig), and are known as owner-operators . Some road transportation is done on regular routes or for only one consignee per run ( full truckload ), while others transport goods from many different loading stations/shippers to various consignees per run ( less-than-truckload ). On some long runs only cargo for one leg of

7254-469: The day. Therefore, compared to humans, they have a relatively small stomach but very long intestines to facilitate a steady flow of nutrients. A 450-kilogram (990 lb) horse will eat 7 to 11 kilograms (15 to 24 lb) of food per day and, under normal use, drink 38 to 45 litres (8.4 to 9.9 imp gal; 10 to 12 US gal) of water . Horses are not ruminants , having only one stomach, like humans. But unlike humans, they can digest cellulose ,

7371-523: The efforts of individual surveyors such as John Metcalf in Yorkshire in the 1760s. British turnpike builders began to realize the importance of selecting clean stones for surfacing while excluding vegetable material and clay, resulting in more durable roads. By the late 18th and early 19th centuries, new methods of highway construction had been pioneered by the work of three British engineers, John Metcalf , Thomas Telford and John Loudon McAdam , and by

7488-460: The federal government's Manual on Uniform Traffic Control Devices ). Modern controlled-access highways originated in the early 1920s in response to the rapidly increasing use of the automobile , the demand for faster movement between cities and as a consequence of improvements in paving processes, techniques and materials. These original high-speed roads were referred to as " dual highways " and have been modernized and are still in use today. Italy

7605-452: The first half of the 20th century. The Long Island Motor Parkway on Long Island , New York , opened in 1908 as a private venture, was the world's first limited-access roadway. It included many modern features, including banked turns , guard rails and reinforced concrete tarmac . Traffic could turn left between the parkway and connectors, crossing oncoming traffic, so it was not a controlled-access highway (or "freeway" as later defined by

7722-401: The front of the mouth, adapted to biting off the grass or other vegetation. There are 24 teeth adapted for chewing, the premolars and molars , at the back of the mouth. Stallions and geldings have four additional teeth just behind the incisors, a type of canine teeth called "tushes". Some horses, both male and female, will also develop one to four very small vestigial teeth in front of

7839-504: The head. Noise affects the behavior of horses and certain kinds of noise may contribute to stress—a 2013 study in the UK indicated that stabled horses were calmest in a quiet setting, or if listening to country or classical music, but displayed signs of nervousness when listening to jazz or rock music. This study also recommended keeping music under a volume of 21 decibels . An Australian study found that stabled racehorses listening to talk radio had

7956-437: The incisors show changes as the horse ages; they develop a distinct wear pattern, changes in tooth shape, and changes in the angle at which the chewing surfaces meet. This allows a very rough estimate of a horse's age, although diet and veterinary care can also affect the rate of tooth wear. Horses are herbivores with a digestive system adapted to a forage diet of grasses and other plant material, consumed steadily throughout

8073-445: The locality. In the United States standardization was first taken at the state level, and late in the century at the federal level. Each country has a Manual of Uniform Traffic Control Devices (MUTCD) and there are efforts to blend them into a worldwide standard. Besides signals, signs, and markings, other forms of traffic control are designed and built into the roadway. For instance, curbs and rumble strips can be used to keep traffic in

8190-412: The macadam with a mixture of tar and sand. Tar-grouted macadam was in use well before 1900 and involved scarifying the surface of an existing macadam pavement, spreading tar, and re-compacting. Although the use of tar in road construction was known in the 19th century, it was little used and was not introduced on a large scale until the motorcar arrived on the scene in the early 20th century. Modern tarmac

8307-490: The metropolitan New York City area, they connected the region's system of parks. When the German autobahns built in the 1930s introduced higher design standards and speeds, road planners and road-builders in the United States started developing and building toll roads to similar high standards. The Pennsylvania Turnpike , which largely followed the path of a partially built railroad, was the first, opening in 1940. After 1940 with

8424-435: The molars, known as "wolf" teeth, which are generally removed because they can interfere with the bit . There is an empty interdental space between the incisors and the molars where the bit rests directly on the gums, or "bars" of the horse's mouth when the horse is bridled . An estimate of a horse's age can be made from looking at its teeth. The teeth continue to erupt throughout life and are worn down by grazing. Therefore,

8541-428: The motorist are those meant to communicate directly with the driver. Broadly, these fall into three categories: signs, signals or pavement markings. They help the driver navigate; they assign the right-of-way at intersections; they indicate laws such as speed limits and parking regulations; they advise of potential hazards; they indicate passing and no passing zones; and otherwise deliver information and to assure traffic

8658-480: The newly invented bicycles could benefit from good country roads. Later on, they did not hold up to higher-speed motor vehicle use. Methods to stabilise macadam roads with tar date back to at least 1834 when John Henry Cassell, operating from Cassell's Patent Lava Stone Works in Millwall , patented "Pitch Macadam". This method involved spreading tar on the subgrade , placing a typical macadam layer, and finally sealing

8775-1030: The number of full hands, followed by a point , then the number of additional inches, and ending with the abbreviation "h" or "hh" (for "hands high"). Thus, a horse described as "15.2 h" is 15 hands plus 2 inches, for a total of 62 inches (157.5 cm) in height. The size of horses varies by breed, but also is influenced by nutrition . Light-riding horses usually range in height from 14 to 16 hands (56 to 64 inches, 142 to 163 cm) and can weigh from 380 to 550 kilograms (840 to 1,210 lb). Larger-riding horses usually start at about 15.2 hands (62 inches, 157 cm) and often are as tall as 17 hands (68 inches, 173 cm), weighing from 500 to 600 kilograms (1,100 to 1,320 lb). Heavy or draft horses are usually at least 16 hands (64 inches, 163 cm) high and can be as tall as 18 hands (72 inches, 183 cm) high. They can weigh from about 700 to 1,000 kilograms (1,540 to 2,200 lb). The largest horse in recorded history

8892-549: The older oriental breeds. Hot bloods tend to be spirited, bold, and learn quickly. They are bred for agility and speed. They tend to be physically refined—thin-skinned, slim, and long-legged. The original oriental breeds were brought to Europe from the Middle East and North Africa when European breeders wished to infuse these traits into racing and light cavalry horses. Muscular, heavy draft horses are known as "cold bloods." They are bred not only for strength, but also to have

9009-417: The organisation had gross earnings of ₹5,995 crores, and with an accumulated loss of ₹6,445 crores. APSRTC has 129 depots across the state. All the 129 depots are 100% computerized. APSRTC having 4 Zones . Maintenance and refurbishment of buses are carried out here. These Zonal workshops having High technology featured equipment for maintenance and refurbishment of buses. APSRTC having 12 regions across

9126-435: The other factors that create the many possible coat colors found in horses. Horses that have a white coat color are often mislabeled; a horse that looks "white" is usually a middle-aged or older gray . Grays are born a darker shade, get lighter as they age, but usually keep black skin underneath their white hair coat (with the exception of pink skin under white markings ). The only horses properly called white are born with

9243-605: The other parts of the bones, and are crucial to development. Depending on maturity, breed, and work expected, horses are usually put under saddle and trained to be ridden between the ages of two and four. Although Thoroughbred race horses are put on the track as young as the age of two in some countries, horses specifically bred for sports such as dressage are generally not put under saddle until they are three or four years old, because their bones and muscles are not solidly developed. For endurance riding competition, horses are not deemed mature enough to compete until they are

9360-426: The pavement, the signal can control and choreograph the turning movements of heavy traffic in the most complex of intersections. In the 1920s traffic engineers learned how to coordinate signals along a thoroughfare to increase its speeds and volumes. In the 1980s, with computers, similar coordination of whole networks became possible. In the 1920s pavement markings were introduced. Initially they were used to indicate

9477-468: The people of Dahomey and their occupation. The Royal Road was built in the late 18th century by King Kpengla which stretched from Abomey through Cana up to Ouidah . The quality of early turnpike roads was varied. Although turnpiking did result in some improvement to each highway, the technologies used to deal with geological features, drainage, and the effects of weather were all in their infancy. Road construction improved slowly, initially through

9594-500: The point of origin and the driver is responsible for ensuring weights conform to maximum allowed standards. This may involve using on-board weight gauges (load pressure gauges), knowing the empty weight of the transport vehicle and the weight of the load, or using a commercial weight scale. In route weigh stations check that gross vehicle weights do not exceed the maximum weight for that particular jurisdiction and will include individual axle weights. This varies by country, states within

9711-440: The pounding of traffic. Concrete is a rigid pavement, which can take heavier loads but is more expensive and requires more carefully prepared subbase. So, generally, major roads are concrete and local roads are asphalt. Concrete roads are often covered with a thin layer of asphalt to create a wearing surface. Modern pavements are designed for heavier vehicle loads and faster speeds, requiring thicker slabs and deeper subbase. Subbase

9828-419: The problem of getting mired in mud. Another improvement, better grading to lessen the steepness of the worst stretches, allowed draft animals to haul heavier loads. A toll road in the United States is often called a turnpike . The term turnpike probably originated from the gate, often a simple pike, which blocked passage until the fare was paid at a toll house (or toll booth in current terminology). When

9945-570: The quantity involved is less than four. Domesticated horses may face greater mental challenges than wild horses, because they live in artificial environments that prevent instinctive behavior whilst also learning tasks that are not natural. Horses are animals of habit that respond well to regimentation, and respond best when the same routines and techniques are used consistently. One trainer believes that "intelligent" horses are reflections of intelligent trainers who effectively use response conditioning techniques and positive reinforcement to train in

10062-647: The rights of light , air and access to highways but to not parkways and freeways; the latter two are distinguished in that the purpose of a parkway is recreation, while the purpose of a freeway is movement. Thus as originally conceived, a freeway is a strip of public land devoted to movement to which abutting property owners do not have rights of light, air or access. Trucking companies (in American English terminology) or haulage companies / hauliers (in British English) accept cargo for road transport. Truck drivers operate either independently – working directly for

10179-493: The road's centerline. Soon after they were coded with information to aid motorists in passing safely. Later, with multi-lane roads they were used to define lanes . Other uses, such as indicating permitted turning movements and pedestrian crossings soon followed. In the 20th century traffic control devices were standardized. Before then every locality decided on what its devices would look like and where they would be applied. This could be confusing, especially to traffic from outside

10296-439: The route (to) is known when the cargo is loaded. Truckers may have to wait at the destination for a backhaul . A bill of lading issued by the shipper provides the basic document for road freight. On cross- border transportation the trucker will present the cargo and documentation provided by the shipper to customs for inspection (for EC see also Schengen Agreement ). This also applies to shipments that are transported out of

10413-496: The same animals as horses. The distinction between a horse and pony is commonly drawn on the basis of height, especially for competition purposes. However, height alone is not dispositive; the difference between horses and ponies may also include aspects of phenotype , including conformation and temperament. The traditional standard for height of a horse or a pony at maturity is 14.2 hands (58 inches, 147 cm). An animal 14.2 hands (58 inches, 147 cm) or over

10530-507: The same bones as would a human on tiptoe. For the protection of the hoof under certain conditions, some horses have horseshoes placed on their feet by a professional farrier . The hoof continually grows, and in most domesticated horses needs to be trimmed (and horseshoes reset, if used) every five to eight weeks, though the hooves of horses in the wild wear down and regrow at a rate suitable for their terrain. Horses are adapted to grazing . In an adult horse, there are 12  incisors at

10647-472: The same color may be distinguished from one another by white markings , which, along with various spotting patterns, are inherited separately from coat color. Many genes that create horse coat colors and patterns have been identified. Current genetic tests can identify at least 13 different alleles influencing coat color, and research continues to discover new genes linked to specific traits. The basic coat colors of chestnut and black are determined by

10764-505: The side. He understood the importance of good drainage, knowing it was rain that caused most problems on the roads. Pierre-Marie-Jérôme Trésaguet established the first scientific approach to road building in France at the same time. He wrote a memorandum on his method in 1775, which became general practice in France. It involved a layer of large rocks, covered by a layer of smaller gravel. The lower layer improved on Roman practice in that it

10881-522: The state. Following are the 12 regions of APSRTC. Andhra Pradesh State Road Transport Corporation has a number of firsts to its credit in India. Road transport The nature of road transportation of goods depends on, apart from the degree of development of the local infrastructure, the distance the goods are transported by road, the weight and volume of an individual shipment, and the type of goods transported. For short distances and light small shipments,

10998-470: The style that best fits with an individual animal's natural inclinations. Horses are mammals . As such, they are warm-blooded , or endothermic creatures, as opposed to cold-blooded, or poikilothermic animals. However, these words have developed a separate meaning in the context of equine terminology, used to describe temperament, not body temperature . For example, the " hot-bloods ", such as many race horses , exhibit more sensitivity and energy, while

11115-503: The sub-base. The surveyor and engineer Thomas Telford also made substantial advances in the engineering of new roads and the construction of bridges. His method of road building involved the digging of a large trench in which a foundation of heavy rock was set. He also designed his roads so that they sloped downwards from the centre, allowing drainage to take place, a major improvement on the work of Trésaguet. The surface of his roads consisted of broken stone. He also improved on methods for

11232-515: The system. Some states are again looking at toll financing for new roads and maintenance, to supplement limited federal funding. In some areas, new road projects have been completed with public-private partnerships funded by tolls, such as the Pocahontas Parkway (I-895) near Richmond, Virginia . Horse at least 48 published The horse ( Equus ferus caballus ) is a domesticated , one-toed , hoofed mammal . It belongs to

11349-478: The taxonomic family Equidae and is one of two extant subspecies of Equus ferus . The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus , into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE , and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies caballus are domesticated, although some domesticated populations live in

11466-544: The term "Warmblood" refers to a specific subset of sport horse breeds that are used for competition in dressage and show jumping . Strictly speaking, the term " warm blood " refers to any cross between cold-blooded and hot-blooded breeds. Examples include breeds such as the Irish Draught or the Cleveland Bay . The term was once used to refer to breeds of light riding horse other than Thoroughbreds or Arabians, such as

11583-465: The times the vehicle is in motion and stopped. Some companies use two drivers per truck to ensure uninterrupted transportation; with one driver resting or sleeping in a bunk in the back of the cab while the other is driving. Truck drivers often need special licenses to drive, known in the U.S. as a commercial driver's license . In the U.K. a large goods vehicle licence is required. For transport of hazardous materials (see dangerous goods ) truckers need

11700-473: The toll was paid the pike, which was mounted on a swivel, was turned to allow the vehicle to pass. Tolls were usually based on the type of cargo being transported, not the type of vehicle. The practice of selecting routes so as to avoid tolls is called shunpiking . This may be simply to avoid the expense, as a form of economic protest (or boycott ), or simply to seek a road less traveled as a bucolic interlude. Companies were formed to build, improve, and maintain

11817-788: The trot with one of the ambling gaits. Horses are prey animals with a strong fight-or-flight response . Their first reaction to a threat is to startle and usually flee, although they will stand their ground and defend themselves when flight is impossible or if their young are threatened. They also tend to be curious; when startled, they will often hesitate an instant to ascertain the cause of their fright, and may not always flee from something that they perceive as non-threatening. Most light horse riding breeds were developed for speed, agility, alertness and endurance; natural qualities that extend from their wild ancestors. However, through selective breeding, some breeds of horses are quite docile, particularly certain draft horses. Horses are herd animals , with

11934-401: The urine of pregnant mares . Humans provide domesticated horses with food, water, and shelter, as well as attention from specialists such as veterinarians and farriers . Depending on breed, management and environment, the modern domestic horse has a life expectancy of 25 to 30 years. Uncommonly, a few animals live into their 40s and, occasionally, beyond. The oldest verifiable record

12051-522: The water would flow out from the crushed stone, instead of becoming mud in clay soils. The Islamic Caliphate later built tar-paved roads in Baghdad . As states developed and became richer, especially with the Renaissance , new roads and bridges began to be built, often based on Roman designs. Although there were attempts to rediscover Roman methods, there was little useful innovation in road building before

12168-422: The wild as feral horses . These feral populations are not true wild horses , which are horses that never have been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors , markings , breeds , locomotion , and behavior. Horses are adapted to run , allowing them to quickly escape predators, and possess

12285-461: The winter and dust in the summer. Early organizers cited Europe where road construction and maintenance was supported by national and local governments. In its early years, the main goal of the movement was education for road building in rural areas between cities and to help rural populations gain the social and economic benefits enjoyed by cities where citizens benefited from railroads, trolleys and paved streets. Even more than traditional vehicles,

12402-1085: The world governing body for horse sport, uses metric measurements and defines a pony as being any horse measuring less than 148 centimetres (58.27 in) at the withers without shoes, which is just over 14.2 hands (58 inches, 147 cm), and 149 centimetres (58.66 in; 14. 2 + 1 ⁄ 2 hands), with shoes. Height is not the sole criterion for distinguishing horses from ponies. Breed registries for horses that typically produce individuals both under and over 14.2 hands (58 inches, 147 cm) consider all animals of that breed to be horses regardless of their height. Conversely, some pony breeds may have features in common with horses, and individual animals may occasionally mature at over 14.2 hands (58 inches, 147 cm), but are still considered to be ponies. Ponies often exhibit thicker manes, tails, and overall coat. They also have proportionally shorter legs, wider barrels, heavier bone, shorter and thicker necks, and short heads with broad foreheads. They may have calmer temperaments than horses and also

12519-569: The world today, developed for many different uses. Horses and humans interact in a wide variety of sport competitions and non-competitive recreational pursuits as well as in working activities such as police work , agriculture , entertainment, and therapy . Horses were historically used in warfare, from which a wide variety of riding and driving techniques developed, using many different styles of equipment and methods of control. Many products are derived from horses, including meat , milk , hide , hair , bone, and pharmaceuticals extracted from

12636-408: Was sequenced in 2007. It contains 2.7 billion DNA base pairs , which is larger than the dog genome , but smaller than the human genome or the bovine genome . The map is available to researchers. Horses exhibit a diverse array of coat colors and distinctive markings , described by a specialized vocabulary. Often, a horse is classified first by its coat color, before breed or sex. Horses of

12753-531: Was " Old Billy ", a 19th-century horse that lived to the age of 62. In modern times, Sugar Puff, who had been listed in Guinness World Records as the world's oldest living pony, died in 2007 at age 56. Regardless of a horse or pony's actual birth date, for most competition purposes a year is added to its age each January 1 of each year in the Northern Hemisphere and each August 1 in

12870-413: Was based on the understanding that the purpose of this layer (the sub-base or base course ) is to transfer the weight of the road and its traffic to the ground, while protecting the ground from deformation by spreading the weight evenly. Therefore, the sub-base did not have to be a self-supporting structure. The upper running surface provided a smooth surface for vehicles while protecting the large stones of

12987-446: Was due to the rise of canals and railroads, which were more efficient (and thus cheaper) in moving freight over long distances. Roads wouldn't again be competitive with rails and barges until the first half of the 20th century when the internal combustion engine replaces draft animals as the source of motive power. With the development, mass production, and popular embrace of the automobile, faster and higher capacity roads were needed. In

13104-415: Was limited to 20 millimetres (1 in) size and stones were checked by supervisors who carried scales. A workman could check the stone size himself by seeing if the stone would fit into his mouth. The importance of the 20 mm stone size was that the stones needed to be much smaller than the 100 mm width of the iron carriage tyres that traveled on the road. Macadam roads were being built widely in

13221-502: Was patented by British civil engineer Edgar Purnell Hooley , who noticed that spilled tar on the roadway kept the dust down and created a smooth surface. He took out a patent in 1901 for tarmac. Hooley's 1901 patent involved mechanically mixing tar and aggregate prior to lay-down and then compacting the mixture with a steamroller . The tar was modified by adding small amounts of Portland cement , resin , and pitch . The first version of modern controlled-access highways evolved during

13338-451: Was probably a Shire horse named Mammoth , who was born in 1848. He stood 21.2 ⁄ 4  hands (86.25 inches, 219 cm) high and his peak weight was estimated at 1,524 kilograms (3,360 lb). The record holder for the smallest horse ever is Thumbelina , a fully mature miniature horse affected by dwarfism . She was 43 centimetres; 4.1 hands (17 in) tall and weighed 26 kg (57 lb). Ponies are taxonomically

13455-466: Was simpler than Telford's, yet more effective at protecting roadways: he discovered that massive foundations of rock upon rock were unnecessary, and asserted that native soil alone would support the road and traffic upon it, as long as it was covered by a road crust that would protect the soil underneath from water and wear. Also unlike Telford and other road builders, McAdam laid his roads as level as possible. His 30-foot-wide (9 m) road required only

13572-540: Was the first country in the world to build controlled-access highways reserved for fast traffic and for motor vehicles only. The Autostrada dei Laghi ("Lakes Motorway"), the first built in the world, connecting Milan to Lake Como and Lake Maggiore , and now parts of the A8 and A9 motorways, was devised by Piero Puricelli and was inaugurated in 1924. This motorway, called autostrada , contained only one lane in each direction and no interchanges. The Bronx River Parkway

13689-615: Was the first road in North America to utilize a median strip to separate the opposing lanes, to be constructed through a park and where intersecting streets crossed over bridges. The Southern State Parkway opened in 1927, while the Long Island Motor Parkway was closed in 1937 and replaced by the Northern State Parkway (opened 1931) and the contiguous Grand Central Parkway (opened 1936). In Germany, construction of
