An express bus service (also known as commuter bus service) is a bus service that is intended to run faster than normal bus services between the same two commuter or destination points.
Express buses operate on a faster schedule by not making as many stops as normal bus services and often taking quicker routes, such as along freeways, or by using dedicated lanes or roadways. Express buses may also operate out of park and rides, in some cases only during rush hour in the peak direction.
Fares on express bus services may be higher than normal parallel services. Many express buses, especially bus rapid transit lines, employ a proof-of-payment scheme, requiring passengers to purchase tickets before boarding the bus, speeding up the service. The vehicles used may also feature amenities like comfortable seating and wireless Internet service, particularly on routes that travel long distances at higher speeds without stopping.
In many cases, an express bus service is identified by a letter before or after the regular route number. For example, in Sydney, the letters L (as in L90), E (as in E70) and X (as in 610X or X84). L indicates that the bus runs along the normal route, while E and X indicate that the bus runs along a more direct route.
Examples of commuter express services would be the Indy Express Bus, which links the communities of Carmel and Fishers to Indianapolis, which connects Nashua, NH and South Station in downtown Boston. An example of an interstate express serive is the Starlight Express, which connects New York City to Charlottesville, VA. A more specialized service is the 351 Meadowlands Express which ferries fans to the Meadowlands Sports Complex from the Port Authority Bus Terminal in midtown Manhattan.
