Bus rapid transit takes part of its name from rail rapid transit, which describes a high-capacity urban public-transit system with its own right-of-way, multiple-car trains at short headways, and longer stop spacing than traditional streetcars and buses. BRT, however, uses buses on a wide variety of rights-of-way, including mixed traffic, dedicated lanes on surface streets, and busways completely separated from traffic. Typical transit speeds of BRT systems range from , which can compare with surface running light rail.
