A bus lane or bus only lane is a lane on a road restricted to buses, and generally used to speed up public transport otherwise held up by traffic congestions. Often taxicabs as well as high occupancy vehicles or motorcycles[1] and even bicycles may use the bus lane as well (though these uses can be controversial, as they can reduce the capacity of the bus lane for its main function). Bus lanes are a central part of bus rapid transit measures.

FunctionEdit

The aim of a bus lane is to give priority to buses and save journey time in places where roads are congested with other traffic. A bus lane is not necessarily very long, as it may only be used to 'detour' a single congestion point such as an intersection. However, some cities have built large stretches of bus lanes which in some places amount to a separate local road system, often called a busway system.

Bus lanes are normally created when the road in question is both likely to be congested as well as heavily traveled by bus routes. Entire roads can be designated as bus lanes (such as Oxford Street in London or Fulton Street in New York City), allowing only buses, taxis and delivery vehicles, or a contra-flow bus lane can allow buses to travel in the opposite direction to other vehicles.[2] Some bus lanes operate on certain times of the day only, usually during rush-hour, allowing all vehicles at other times, and it is common to have bus lanes in only one direction (such as for the main direction of the morning rush hour traffic, with the buses using normal lanes in the other direction).

Sometimes, bus lanes receive different sets of traffic signals as well.

HistoryEdit

On 26 February 1968, the first bus lane in London was put into service on Vauxhall Bridge.[citation needed] By 1972, there were over 140 km of with-flow bus lanes located in 100 cities within OECD member countries, and the network was found to be growing substantially in the following decades.[3]

CriticismEdit

The installation of bus lanes requires additional space to either be constructed (increasing the impact of the road on the surrounding area, and possibly requiring private land)[4] or taken from existing lanes (thus reducing the capacity of the road for private vehicles). The latter is especially controversial with many road users when this is actually an ancillary reason (i.e. when local authorities want to explicitly combine improved public transport options with reducing or at least not improving convenience for motorists).[5]

They can also become inefficient if weak traffic enforcement encourages illegal parking on them (for example in shopping areas). The bus then has to merge back into traffic, which may be totally stopped, causing substantial schedule delays.[citation needed] They are also often used by vehicles not authorised, which reduces their capacity for the intended purpose.[6]
