19-537: Madingley Road is a major arterial road linking central Cambridge , England with Junction 13 of the M11 motorway . It passes by West Cambridge , a major new site where some University of Cambridge departments are being relocated. The road is designated the A1303 . At the eastern end, the A1303 continues as Northampton Street , then Chesterton Lane and Chesterton Road . There is

38-465: A counterflow lane or contraflow lane is a lane in which traffic flows in the opposite direction of the surrounding lanes. Contraflow lanes are often used for bicycles or bus rapid transit on what are otherwise one-way streets . In a sample configuration for buses, a street might have four lanes: the outermost lanes are reserved for buses in both directions, while the center two lanes are available for general traffic in only one direction. Thus,

57-495: A bus-only contraflow lane on Macquarie St in Hobart , Tasmania , Australia . Authorised buses, emergency vehicles and taxis use a contraflow lane on Petrie Tce, Brisbane , Queensland , Australia. Tram lanes are an extension to this system found in cities with curbside streetcar networks. For example, tram lanes in Zagreb can be used only by trams, buses, and taxicabs. Contraflow

76-577: A contraflow lane may be set up on the other side of the central reservation. There are similar setups with slightly different usages, although the terms may be commonly used interchangeably. Contraflow Lane: Typically used to refer to a bus lane running against a one-way street through the opposite direction Contraflow Lane Reversal : Typically used to refer to a temporary setup of a lane running opposite to normal during special times, such as emergency evacuations, sports tournaments, or road construction/repairs. Reversible Lane : Typically used to refer to

95-506: A junction with the A1134 ( Queen's Road ) to the south. At the Cambridge (east) end of the road, there are a number of large detached residences. Side streets include Grange Road and Wilberforce Road . The village of Coton is south of the western end of Madingley Road. The following are located on or close to Madingley Road: The following have lived on or close to Madingley Road: One of

114-517: A lane specifically designed to facilitate different directional usage regularly, with changes sometimes as frequent as twice a day. Contraflow bus lanes , areas in which a dedicated lane of an otherwise one way street is reversed for buses and other mass transit, exist in locations such as: From June 1990 to June 2002, a similar line existed in Montreal , along Pie-IX Boulevard ; this was indefinitely suspended after two fatalities. Government buses use

133-642: A one-way street that does include contraflow for bicycles, because they are too accustomed to all one-way streets including bicycles. In the United Kingdom, it is standard since 2020 to encourage highway authorities to allow cycles to take a shorter and perhaps safer routes on narrow one-way residential streets. On streets with less than 1000 vehicles a day and a speed limit of 20 mph, contraflow lanes do not require lane markings where, although appear on upright signage. As part of new or improved one-way road layouts, contraflow cycle lanes should be considered. In

152-468: Is a common part of decent cycling infrastructure and is often seen on one-way streets. A standard example is that car and other vehicular traffic might have only one lane while on both sides there are bike lanes; one going in the same direction as the vehicular traffic, the other (the contraflow bike lane) allows cyclists to safely go in the opposite direction to the cars. This is allowed as the road may not be wide enough for two lanes of car traffic but there

171-506: Is enough room to allow for the additional bicycle lane; and without it cyclists may be forced to take a long, and perhaps unsafe, detour. Another example is the same as the above but there is only one bike lane, the contraflow lane, and bicycles travelling in the same direction as the cars share the cars' lane. This solution would be more suited to very narrow roads or ones with light traffic. In Belgium since about 2005, and in France since 2010,

190-537: The Port Authority of New York and New Jersey , the bi-state agency that also operates the 2.5-mile (4.02 km) contraflow lane along the left lane of three westbound lanes. The XBL serves over 1,800 buses, which transport more than 65,000 persons, each morning and is a major component of the morning "inbound" commutation crossing the Hudson River . When lanes on motorways are closed for repair and maintenance,

209-496: The Netherlands, most one-way streets are two way for cyclists, although this is not always marked by a counterflow lane. This is presented as a 'one-way street, except for cyclists'. One-way streets that do not include contraflow for bicycles are rare and are usually only found as pairs of a single street (with very large median) that are too far apart to be presented as a single street. It is not uncommon for cyclists to fail to notice

228-579: The United States, the town of Provincetown , Massachusetts on Cape Cod has long allowed cycling in both directions on its three-mile long main street, Commercial Street . There is no marked cycle lane. This unusual condition required special state legislation in 1977 to give the local government permission to set its own rules for the street. Contraflow cycling is often assumed to be associated with higher accidents risks, but where it has been properly evaluated, contraflow cycling actually seems to reduce

247-485: The backbone of a traffic network and should be designed to afford the highest level of service , as is practical, as per the aforementioned "Traffic Engineering Handbook". The construction and development of arterial roads is achieved through two methods. By far the most common is the upgrading of an existing right-of-way during subdivision development. When existing structures prohibit the widening of an existing road however, bypasses are often constructed. Because of

266-486: The busier junctions. Speed limits are typically between 30 and 50 mph (50 and 80 km/h), depending on the density of use of the surrounding development. In school zones, speeds may be further reduced; likewise, in sparsely developed or rural areas, speeds may be increased. In western Canada, where freeways are scarce compared to the rest of North America, flashing early-warning amber lights are sometimes placed ahead of traffic lights on heavy signalized arterial roads so

285-509: The default position in towns has been for one-way streets to be available for cycling in either direction, known in French as sens unique limité (SUL) in Belgium and double sens cyclable (DSC) in France. In this case, a contraflow cycle lane is often marked in paint, with dotted white lines and ideograms of a bicycle, either all the way along the street if busy, or more commonly just at junctions. In

304-1049: The last known stands in England of rare semi-mature Plot elms , the Madingley Road elms descended from those described by botanists Elwes and Henry in 1913 and studied by R. H. Richens in 1960, was destroyed by Cambridge City Council for road-widening, between about 2007 and 2014. 52°12′43″N 0°05′50″E  /  52.2119°N 0.0972°E  / 52.2119; 0.0972 Arterial road In traffic engineering hierarchy, an arterial road delivers traffic between collector roads and freeways . For new arterial roads, intersections are often reduced to increase traffic flow . In California, arterial roads are usually spaced every half mile, and have intersecting collector(s) and streets. The Traffic Engineering Handbook describes "Arterials" as being either principal or minor. Both classes serve to carry longer-distance flows between important centers of activity. Arterials are laid out as

323-453: The placement and general continuity of arterial road corridors , sewers, water mains, conduits and other infrastructure are placed beneath or beside the roadbed. In North America, signalized at-grade intersections are used to connect arterials to collector roads and other local roads (except where the intersecting road is a minor side street, in which case a stop sign is used instead). In Europe, large roundabouts are more commonly seen at

342-1046: The speed limits can be raised to speeds of over 80 km/h. These warning lights are commonly found on high-speed arterial roads in British Columbia. The width of arterial roads can range from four lanes to ten or even more; either as a dual carriageway or sharing a common center lane, such as a contraflow lane or as a central turning lane. As with other roadway environmental consequences derive from arterial roadways, including air pollution generation, noise pollution and surface runoff of water pollutants. Air pollution generation from arterials can be rather concentrated, since traffic volumes can be relatively high, and traffic operating speeds are often low to moderate. Sound levels can also be considerable due to moderately high traffic volumes characteristic of arterials, and also due to considerable braking and acceleration that often occur on arterials that are heavily signalized. Contraflow lane In transport engineering nomenclature ,

361-575: The street functions as two-way for buses, but one-way for all other vehicles. In certain situations, reversible lanes will be contraflow for a portion of the day. The Lincoln Tunnel XBL to the Lincoln Tunnel is a contraflow exclusive bus lane for buses during the morning peak period. The XBL lane is fed by the New Jersey Turnpike at Exits 16E and 17, and New Jersey Route 3 . The helix, tunnel, and terminal are owned and operated by
