Key facts: 

• Buses have a dedicated lane through the major roadways in the city (usually placed in the center/median of the roadway with access ramps and overpasses to connect pedestrians to the median). "troncal" is the term.
• Bus stations have platforms that line up with the bus threshold for easy access to all passengers including those on wheelchairs.
• Up to 1400 main buses (long buses - people pay a fare with card) and over 400 feeder buses (that run free) that connect to the main lines.
