Transantiago is the public transportation system in Santiago, the capital of Chile. Launched in 2007, it integrates buses and the Metro to provide efficient travel across the city. The system aims to improve mobility and reduce traffic congestion by offering a coordinated network of routes. The Transantiago system features a range of bus services, including express and local routes, all connected to the Metro stations. Passengers use a contactless card called the BIP! card to pay for their fares, making the process quick and convenient. Overall, Transantiago plays a crucial role in the daily commute for millions of residents.
