Bus rapid transit (BRT, BRTS, busway, 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 roadway that is 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 BRT system was the Rede Integrada de Transporte ('Integrated Transportation Network') in Curitiba, Brazil, which entered service in 1974. This inspired many similar systems around Brazil and the world, such as TransMilenio in Bogotá, Colombia, which opened in 2000. As of November 2016[update], a total of 207 cities in six continents have implemented BRT systems, accounting for 5,468 km (3,398 mi) of BRT lanes. As of November 2016[update], about 34.3 million passengers use BRT worldwide every day, of which about 21.1 million passengers ride daily in Latin America, which has the most cities with BRT systems, with 69, led by Brazil with 34 cities. The Latin American countries with the most daily ridership are Brazil (11.9M), Colombia (3.1M), and Mexico (2.4M). In the other regions, China (4.4M) and Iran (2.1M) also stand out. Currently, TransJakarta considered as the largest BRT network in the world with approximately 230.9 kilometres (143.5 mi) of corridors connecting the Indonesian capital city.
