This highly effective local transport system, which is accessible to all sections of the population, was built in just 24 months. The existing bus operators were integrated into the system. TransMilenio has been so successful from the start that a more comprehensive network is now being rolled out across the city. By 2015, the plan is to make the network so comprehensive that 80 percent of the city’s residents will have a bus stop within 500 m of their home. The system works as well as a subway system. More than 1,000 diesel-powered articulated buses – 350 of which are from Mercedes-Benz – are deployed on the exclusive bus lanes. The city’s already wide roads helped the system’s rapid implementation.
