a demand for equal access public service provision. Transit buses are also now subject to various disability discrimination acts in several jurisdictions which dictate various design features also applied to other vehicles in some cases. Due to the high number of high-profile urban operations, transit buses are at the forefront of bus electrification, with hybrid electric bus, all-electric bus and fuel cell bus development and testing aimed at reducing fuel usage, shift to green electricity and decreasing environmental impact. Developments of the transit bus towards higher capacity bus transport include tram-like vehicles such as guided buses, longer bi-articulated buses and tram-like buses such as the Wright StreetCar, often as part of bus rapid transit schemes. Fare collection is also seeing a shift to off-bus payment, with either the driver or an inspector verifying fare payments. Commuter bus service A commuter or express bus service is a fixed-route bus characterized by service predominantly in one direction during peak periods, limited stops, use of multi-ride tickets and routes of extended length, usually between the central business district and outlying suburbs. Commuter bus service also may include other service, characterized by a limited route structure, limited stops and a coordinated relationship with another mode of transportation. They may closely follow the routing of a conventional bus route but not stopping at every stop or not making detours such as into residential or commercial areas that conventional routes may take.
