The City of Buenos Aires has successfully implemented two key projects to contribute to sustainable transport: the first BRT (Metrobus) and Bike Sharing System (Mejor en Bici) in the country. Metrobus, launched in May 2011, is the first bus rapid transit system in the city and in the country. It operates 24 hours a day, 365 days a year, with a 2 minute frequency during peak hours and between 2 and 4 minutes off peak. Night service is every 10 to 15 minutes. Fares are equal to those of regular buses within the city. Metrobus travels 12km one way and avoids unnecessary transfers. There is already evidence of a reduction in travel time and increase in the number of passengers.

The city has also developed the on-street bike lane network across the city's central area, connecting key transport hubs, office buildings and universities. The network will soon be reaching the catchment area. To ensure cyclists' protection, the city also implemented segregated bike lanes from car traffic, as well as traffic calming devices at intersections. Bicycle parking is also located throughout the city along roads and near public buildings. The city launched a successful bike share system on 1st December 2010, with 72 bikes and 3 stations. Over the first 20 days there was an average of 110 bike trips per day, 670 overall bike trips and 850 users. As of October 2011 the system has grown to 700 bikes, 20 stations, an average of 2,500 daily bike trips, 260,000 overall trips, and 25,000 users.
