context_page_description: Bus rapid transit, also called a busway or transitway, is a bus-based public transport system designed to improve capacity and reliability relative to a conventional bus system. Typically, a BRT system includes roadways that are dedicated to buses, and gives priority to buses at intersections where buses may interact with other traffic; alongside design features to reduce delays caused by passengers boarding or leaving buses, or purchasing fares. BRT aims to combine the capacity and speed of a metro with the flexibility, lower cost and simplicity of a bus system.
  The first comprehensive BRT system in the world was the Busway in Runcorn New Town, England which entered service in 1971. As of March 2018, a total of 166 cities in six continents have implemented BRT systems, accounting for 4,906 km of BRT lanes and about 32.2 million passengers every day, of which about 19.6 million passengers ride daily in Latin America, which has the most cities with BRT systems, with 54, led by Brazil with 21 cities. The Latin American countries with the most daily ridership are Brazil, Colombia, and Mexico. In the other regions, China and Iran also stand out.
context_section_description: Bus-only lanes make for faster travel and ensure that buses are not delayed by mixed traffic congestion. A median alignment bus-only keeps buses away from busy curb-side side conflicts, where cars and trucks are parking, standing and turning. Separate rights of way may be used such as the completely elevated Xiamen BRT. Transit malls or 'bus streets' may also be created in city centers.
