50-732: Chengdu Bus Rapid Transit is a bus rapid transit system in Chengdu , the capital of Sichuan Province , in the People's Republic of China . The current system consists of a loop line integrated with the Chengdu Second Ring Road with dedicated bus lanes running in the center two lanes of the expressway. Transfers are available to several Chengdu Metro stations. The line began a free trial run on May 31, 2013, and started official operation on June 11, 2013. It has 29 center platform stations located in expressway median which requires special buses with
100-611: A "BHLS" (stands for Bus with a High Level of Service ). The term transitway was originated in 1981 with the opening of the OC Transpo transitway in Ottawa , Ontario , Canada. Critics have charged that the term "bus rapid transit" has sometimes been misapplied to systems that lack most or all the essential features which differentiate it from conventional bus services. The term " bus rapid transit creep " has been used to describe severely degraded levels of bus service which fall far short of
150-515: A BRT system to 35,000 passengers per hour. The single-lane roads of Istanbul Metrobus had been frequently blocked by Phileas buses breaking down, causing delays for all the buses in a single direction. After focusing on Mercedes-Benz buses, capacity increased to 45,000 pph. Light rail, by comparison, has reported passenger capacities between 3,500 pph (mainly street running) to 19,000 pph (fully grade-separated ). Bus rapid transit creep Bus rapid transit creep ( BRT creep )
200-451: A high-end service only to find out that we just painted the buses a different color". According to Dan Malouff, a transit planner who was one of the earliest people to use the phrase, the slippery slope towards BRT creep varies widely from system to system. He says in a piece republished by The Washington Post that "there are a thousand corners like that you can cut that individually may or may not hurt too much, but collectively add up to
250-428: A low-noise, low-emissions "hush mode" (in which the diesel engine operates but does not exceed idle speed ) when underground. The need to provide electric power in underground environments brings the capital and maintenance costs of such routes closer to those of light rail, and raises the question of building or eventually converting to light rail. In Seattle, the downtown transit tunnel was retrofitted for conversion to
300-449: A result, less forced ventilation will be required in tunnels to achieve the same air quality. Another alternative is to use electric propulsion, which Seattle 's Metro Bus Tunnel and Boston 's Silver Line Phase II implemented. In Seattle, dual-mode (electric/diesel electric) buses manufactured by Breda were used until 2004, with the center axle driven by electric motors obtaining power from trolley wires through trolley poles in
350-414: A separated right-of-way (at least for the majority of the line and during peak periods), defined stations, short headways and signal priority." One drawback to the phrase is that it uses "creep" in a way that is contradictory to other terms such as " scope creep ", " feature creep ", and " mission creep ". "BRT creep" refers to how features can be eaten away due to lack of funding or political will, while
400-451: A shared hybrid-bus and light-rail facility in preparation for Seattle's Central Link Light Rail line, which opened in July 2009. In March 2019, expansion of the light rail in the tunnel moved busses back to surface streets. Bi-articulated battery electric buses cause no problems in tunnels anymore but provide BRT capacity. A BRT system can be measured by a number of factors. The BRT Standard
450-419: A static map, featuring services like trip planning, live arrival and departure times, up-to-date line schedules, local station maps, service alerts, and advisories that may affect one's current trip. Transit and Moovit are examples of apps that are available in many cities around the world. Some operators of bus rapid transit systems have developed their own apps, like Transmilenio. These apps even include all
500-477: A total daily ridership), in the developing world this capacity constraint (or rumor of a capacity constraint) was a significant argument in favor of heavy rail metro investments in some venues. When TransMilenio opened in 2000, it changed the paradigm by giving buses a passing lane at each station stop and introducing express services within the BRT infrastructure. These innovations increased the maximum achieved capacity of
550-490: Is a trolleybus , electric bus and public transport bus service system designed to have much more capacity , reliability , and other quality features than a conventional bus system. Typically, a BRT system includes roadways that are dedicated to buses , and gives priority to buses at intersections where buses may interact with other traffic; alongside design features to reduce delays caused by passengers boarding or leaving buses, or paying fares . BRT aims to combine

#1733085222936600-488: Is a phenomenon where bus systems that fail to meet the requirements for being considered "true bus rapid transit " are designated as bus rapid transit regardless. These systems are often marketed as a fully realized bus rapid transit system, but end up being described as more of an improvement to regular bus service by proponents of the "BRT creep" term. The Institute for Transportation and Development Policy published several guidelines in an attempt to define what constitutes
650-581: Is a risk of a dangerous gap between bus and platform , and is even greater due to the nature of bus operations. Kassel curbs or other methods may be used to ease quick and safe alignment of the BRT vehicle with a platform. A popular compromise is low-floor buses with a low step at the door, which can allow easy boarding at low-platform stops compatible with other buses. This intermediate design may be used with some low- or medium-capacity BRT systems. The MIO system in Santiago de Cali, Colombia, pioneered in 2009
700-530: Is known as the Jiannan Avenue BRT and is projected to open in 2018. Additional BRT lines are planned to radiate from the loop with lines heading west to Wenjiang District , east via Shanbanqiao Road, and south to Tianfu New Area . Additionally, another BRT loop along the Third Ring Road was proposed. Bus rapid transit Bus rapid transit ( BRT ), also referred to as a busway or transitway ,
750-569: Is less complex than rail maintenance. Moreover, buses are more flexible than rail vehicles, because a bus route can be altered, either temporarily or permanently, to meet changing demand or contend with adverse road conditions with comparatively little investment of resources. The first use of a protected busway was the East Side Trolley Tunnel in Providence , Rhode Island . It was converted from trolley to bus use in 1948. However,
800-483: Is not effective. On the other hand, "For trunk line capacities below about 1,600 spaces per hour, the headway-versus-cost trade-off favors BRT". ) This type of stripping down service is known as BRT creep. The most extreme versions of BRT creep lead to systems that cannot even truly be recognized as "Bus Rapid Transit". For example, a rating from the Institute for Transportation and Development Policy (ITDP) determined that
850-459: Is today over 18.5 miles long. The OC Transpo BRT system in Ottawa , Canada, was introduced in 1983. The first element of its BRT system was dedicated bus lanes through the city centre, with platformed stops. The introduction of exclusive separate busways (termed 'Transitway') occurred in 1983. By 1996, all of the originally envisioned 31 km Transitway system was in operation; further expansions were opened in 2009, 2011, and 2014. As of 2019,
900-508: The BRT Standard promoted by the Institute for Transportation and Development Policy (ITDP) and other organizations. Compared to other common transit modes such as light rail transit (LRT), bus rapid transit (BRT) service is attractive to transit authorities because it does not cost as much to establish and operate: no track needs to be laid, bus drivers typically require less training and less pay than rail operators, and bus maintenance
950-498: The Boston Silver Line was best classified as "Not BRT" after local decision makers gradually decided to do away with most BRT-specific features. The study also evaluates New York City's Select Bus Service (which is supposed to be BRT-standard) as "Not BRT". Some American systems reviewed had so few essential characteristics that calling them a BRT system at all does a disservice to efforts to gain broader adoption of BRT in
1000-605: The Indonesian capital city . Bus rapid transit is a mode of mass rapid transit (MRT) and describes a high-capacity urban public-transit system with its own right of way , vehicles at short headways , platform-level boarding, and preticketing. The expression "BRT" is mainly used in the Americas and China; in India, it is called "BRTS" (BRT System); in Europe it is often called a "busway" or
1050-906: The MIO in Cali since November 2008, Metrolinea in Bucaramanga since December 2009, Megabús in Pereira since May 2009. This design is also used in Johannesburg 's Rea Vaya . The term "station" is more flexibly applied in North America and ranges from enclosed waiting areas ( Ottawa and Cleveland ) to large open-sided shelters ( Los Angeles and San Bernardino ). A unique and distinctive identity can contribute to BRT's attractiveness as an alternative to driving cars, (such as Viva, Max, TransMilenio, Metropolitano, Metronit, Select) marking stops and stations as well as

Research of the Institute for Transportation and Development Policy (ITDP) shows a capacity ranking of MRT modes, based on reported performance of 14 light rail systems, 14 heavy rail systems (just 1-track + 3 2-track-systems "highest capacity") and 56 BRT systems. The study concludes, that BRT-"capacity on TransMilenio exceeds all but the highest capacity heavy rail systems, and it far exceeds
1150-639: The United States, BRT began in 1977, with Pittsburgh's South Busway , operating on 4.3 miles (6.9 km) of exclusive lanes. Its success led to the Martin Luther King Jr. East Busway in 1983, a fuller BRT deployment including a dedicated busway of 9.1 miles (14.6 km), traffic signal preemption , and peak service headway as low as two minutes. After the opening of the West Busway , 5.1 miles (8.2 km) in length in 2000, Pittsburgh's Busway system
1200-516: The United States. Worried about similar circumstances, Virginia writer Kevin Beekman urges residents in areas planned for BRT development to use the ITDP scoring worksheet ( BRT Standard ) as an assessment tool. Another Washington-area writer, Dan Reed, furthers this sentiment, writing that if BRT creep is allowed to reach its full conclusion, it's "bad for commuters, but it's also bad for taxpayers who were sold
1250-419: The buses. Large cities usually have big bus networks. A map showing all bus lines might be incomprehensible, and cause people to wait for low-frequency buses that may not even be running at the time they are needed. By identifying the main bus lines having high-frequency service, with a special brand and separate maps, it is easier to understand the entire network. Public transit apps are more convenient than
1300-764: The capacity and speed of a light rail transit (LRT) or mass rapid transit (MRT) system with the flexibility, lower cost and simplicity of a bus system. The world's first BRT system was the Runcorn Busway in Runcorn New Town, England, which entered service in 1971. As of March 2018 , a total of 166 cities in six continents have implemented BRT systems, accounting for 4,906 km (3,048 mi) of BRT lanes and about 32.2 million passengers every day. The majority of these are in Latin America , where about 19.6 million passengers ride daily, and which has
1350-585: The center of major arterial roads, in 1980 the Curitiba system added a feeder bus network and inter-zone connections, and in 1992 introduced off-board fare collection, enclosed stations, and platform-level boarding. Other systems made further innovations, including platooning (three buses entering and leaving bus stops and traffic signals at once) in Porto Alegre , and passing lanes and express service in São Paulo . In
1400-591: The central part of the Transitway has been converted to light rail transit , due to the downtown section being operated beyond its designed capacity. In 1995, Quito , Ecuador, opened MetrobusQ its first BRT trolleybuses in Quito , using articulated trolleybuses. The TransMilenio in Bogotá , Colombia, opening in 2000, was the first BRT system to combine the best elements of Curitiba's BRT with other BRT advances, and achieved
1450-568: The concept while sketching on the back of an envelope. The town was designed around the transport system, with most residents no more than five minutes walking distance, or 500 yards (460 m), from the Busway. The second BRT system in the world was the Rede Integrada de Transporte (RIT, integrated transportation network ), implemented in Curitiba , Brazil, in 1974. The Rede Integrada de Transporte
1500-443: The difference between BRT and a regular bus". Major compromises in service are highlighted by one or more common symptoms: buses run in shared general purpose lanes or HOV lanes rather than dedicated lanes, using traditional bus stops instead of full-featured stations, eliminating fare pre-payment and all-door boarding which slows passenger boarding, and offering no priority at traffic lights. Detroit writer Michael Jackman mentions
1550-499: The doors on the left. The loop is served by Lines K1, K1A, K2 and K2A. All buses have wifi. A new 7.8 km (4.8 mi) radial line heading northeast from the BRT loop to Qingbaijiang District is under construction. The line, called the Fenghuang Shan (Phoenix Mountain) BRT, is scheduled to open in 2017. Another 4.5 km (2.8 mi) elevated BRT line heading south of the BRT loop is also currently under construction. This line

1600-428: The downside, however, this flexibility can lead to service enhancements being whittled away in a manner that is not possible once rail solutions have been built. (Transit agencies have incentive to strip down service after a BRT route is initially presented, partially because BRT might have up to 24% higher operating costs than rail solutions of a similar size according to a parametric cost model, if traffic signal priority
1650-627: The first BRT system in the world was the Runcorn Busway in Runcorn , England. First conceived in the Runcorn New Town Masterplan in 1966, it opened for services in October 1971 and all 22 kilometres (14 mi) were operational by 1980. The central station is at Runcorn Shopping City where buses arrive on dedicated raised busways to two enclosed stations. Arthur Ling , Runcorn Development Corporation's Master Planner, said that he had invented
1700-442: The following features: Bus-only lanes make for faster travel and ensure that buses are not delayed by mixed traffic congestion . A median alignment bus-only keeps buses away from busy curb-side side conflicts, where cars and trucks are parking, standing and turning. Separate rights of way may be used such as the completely elevated Xiamen BRT . Transit malls or 'bus streets' may also be created in city centers. Fare prepayment at
1750-662: The green phase or reducing the red phase in the required direction compared to the normal sequence. Prohibiting turns may be the most important measure for moving buses through intersections. The station platforms for BRT systems should be level with the bus floor for quick and easy boarding, making it fully accessible for wheelchairs, disabled passengers and baby strollers, with minimal delays. High-level platforms for high-floored buses makes it difficult to have stops outside dedicated platforms, or to have conventional buses stop at high-level platforms, so these BRT stops are distinct from street-level bus stops. Similar to rail vehicles, there
1800-628: The highest capacity and highest speed BRT system in the world. In January 2004 the first BRT in Southeast Asia, TransJakarta , opened in Jakarta , Indonesia. As of 2015 , at 210 kilometres (130 mi), it is the longest BRT system in the world. Africa's first BRT system was opened in Lagos , Nigeria, in March 2008 but is considered a light BRT system by many people. Johannesburg , South Africa, BRT Rea Vaya ,
1850-447: The highest light rail system." Performance data of 84 systems show More topical are these BRT data After the first BRT system opened in 1971, cities were slow to adopt BRT because they believed that the capacity of BRT was limited to about 12,000 passengers per hour traveling in a given direction during peak demand. While this is a capacity rarely needed in the US (12,000 is more typical as
1900-474: The most cities with BRT systems, with 54, led by Brazil with 21 cities. The Latin American countries with the most daily ridership are Brazil (10.7 million), Colombia (3.0 million), and Mexico (2.5 million). In the other regions, China (4.3 million) and Iran (2.1 million) stand out. Currently, TransJakarta is the largest BRT network in the world, with about 251.2 kilometres (156.1 mi) of corridors connecting
1950-574: The removal of "signal pre-emption, dedicated lanes separated by concrete berms, heated, ADA-compliant stations, preticketing, and more" as indicators of BRT creep. Author and activist Matthew Yglesias has argued in Slate Magazine that BRT creep is a very real worry, but that the issue is not "a problem with buses , it's a problem with cheapskates ". Houston Tomorrow points out some ways local legislation can prevent BRT creep: "The new section on Bus Rapid Transit specifically defines it as having
2000-858: The right side of the street. Groups of criteria form the BRT Standard 2016, which is updated by the Technical Committee of the BRT Standard. High-capacity vehicles such as articulated or even bi-articulated buses may be used, typically with multiple doors for fast entry and exit. Double-decker buses or guided buses may also be used. Advanced powertrain control may be used for a smoother ride. Bottleneck BRT stations typically provide loading areas for simultaneous boarding and alighting of buses through multiple doors coordinated via displays and loudspeakers. An example of high-quality stations include those used on TransMilenio in Bogotá since December 2000,
2050-771: The schedules and live arrival times and stations for buses that feed the BRT, like the SITP (Sistema Integrado de Transporte Público or Public Transit Integrated System) in Bogotá . A special issue arises in the use of buses in metro transit structures. Since the areas where the demand for an exclusive bus right-of-way are apt to be in dense downtown areas where an above-ground structure may be unacceptable on historic, logistic, or environmental grounds, use of BRT in tunnels may not be avoidable. Since buses are usually powered by internal combustion engines , bus metros raise ventilation issues similar to those of motor vehicle tunnels. Powerful fans typically exchange air through ventilation shafts to

2100-492: The station, instead of on board the bus, eliminates the delay caused by passengers paying on board. Fare machines at stations also allow riders to purchase multi-ride stored-value cards and have multiple payment options. Prepayment also allows riders to board at all doors, further speeding up stops. Prohibiting turns for traffic across the bus lane significantly reduces delays to the buses. Bus priority will often be provided at signalized intersections to reduce delays by extending
2150-404: The subway, and with the rear axle driven by a conventional diesel powertrain on freeways and streets. Boston is using a similar approach, after initially using trolleybuses pending delivery of the dual-mode vehicles that was completed in 2005. In 2004, Seattle replaced its "Transit Tunnel" fleet with diesel-electric hybrid buses, which operate similarly to hybrid cars outside the tunnel and in
2200-417: The surface; these are usually as remote as possible from occupied areas, to minimize the effects of noise and concentrated pollution. A straightforward way to reduce air quality problems is to use internal combustion engines with lower emissions. The 2008 Euro V European emission standards set a limit on carbon monoxide from heavy-duty diesel engines of 1.5 g/kWh, one third of the 1992 Euro I standard. As
2250-696: The term "true BRT", known as the BRT Standard , in an attempt to avert this phenomenon. Proponents of the "Bus Rapid Transit" term cite it as a form of mass transit that uses buses in a dedicated right-of-way, ideally providing speed and volume of service similar to light rail . A commonly cited advantage of BRT is the lack of need to build new rail infrastructure, as new rail has greater initial capital costs than using existing roads and cannot be changed easily. The flexibility of BRT, with its greater similarity to other forms of bus transportation, also means that there are fewer obstacles to removing expensive or difficult-to-implement features such as dedicated lanes. On
2300-428: The theoretical maximum throughput measured in passengers per hour per direction (PPHPD) for a single traffic lane is some 150,000 passengers per hour (250 passengers per vehicle, one vehicle every 6 seconds). In real world conditions BRT Rio (de Janeiro, BRS Presidente Vargas) with 65.000 PPHPD holds the record, TransMilenio Bogotá and Metrobus Istanbul perform 49,000 – 45,000 PPHPD, most other busy systems operating in
2350-499: The use of dual buses, with doors on the left side of the bus that are located at the height of high-level platforms, and doors on the right side that are located at curb height. These buses can use the main line with its exclusive lanes and high level platforms, located on the center of the street and thus, boarding and leaving passengers on the left side. These buses can exit the main line and use normal lanes that share with other vehicles and stop at regular stations located on sidewalks on
2400-438: Was developed by the Institute for Transportation and Development Policy (ITDP) to score BRT corridors, producing a list of rated BRT corridors meeting the minimum definition of BRT. The highest rated systems received a "gold" ranking. The latest edition of the standard was published in 2016. Other metrics used to evaluate BRT performance include: Based on this data, the minimum headway and maximum current vehicle capacities,
2450-490: Was inspired by the previous transport system of the National Urban Transport Company of Peru (In Spanish: ENATRU ), which only had quick access on Lima downtown , but it would not be considered BRT itself. Many of the elements that have become associated with BRT were innovations first suggested by Carlos Ceneviva, within the team of Curitiba Mayor Jaime Lerner . Initially just dedicated bus lanes in
2500-661: Was the first true BRT in Africa, in August 2009, carrying 16,000 daily passengers. Rea Vaya and MIO (BRT in Cali , Colombia, opened 2009) were the first two systems to combine full BRT with some services that also operated in mixed traffic, then joined the BRT trunk infrastructure. In 2017 Marrakesh , Morocco, opened its first BRT Marrakesh trolleybus system (BHNS De Marrakesh) trolleybuses Corridors of 8 km (5.0 mi), of which 3 km (1.9 mi) of overhead wiring for operation as trolleybus. BRT systems normally include most of
