An intercity bus service (North American English) or intercity coach service (British English and Commonwealth English), also called a long-distance, express, over-the-road, commercial, long-haul, or highway bus or coach service, is a public transport service using coaches to carry passengers significant distances between different cities, towns, or other populated areas. Unlike a transit bus service, which has frequent stops throughout a city or town, an intercity bus service generally has a single stop at one location in or near a city – usually at a transit interchange – and travels long distances without stopping at all. Intercity bus services may be operated by government agencies or private industry, for profit and not for profit. Intercity coach travel can serve areas or countries with no train services, or may be set up to compete with trains by providing a more flexible or cheaper alternative.
The conversion of intercity road lanes into public transit only lanes can significantly increase the efficacy of the public transit system, especially when done in scale as in Israel. However, lack of enforcment can reduce the efficiency and speed of intercity buses on such lanes. The creation on scale of public transit only intercity lanes through the conversion of existing car lanes into public transit only lanes can lead to major boosts to the economy according to The Marker.
