Mexico City' Government is developing and implementing new measures to improve their inhabitants life’s quality, by building a healthy, competitive, equitable and sustainable city. One of these measures is to promote daily, massive and safe bicycle use as an alternative transport mode, activity that benefits more citizens every day. This is the reason why in 2007 Mexico City’s government presented the Mexico City’s Bicycle Mobility Strategy (BMS). In 2010, Individual Transport System ECOBICI, Mexico city’s bike sharing system was launched in order to make bicycles more accessible to the population and to promote intermodality with other public transport systems. Some of the main issues we faced were the unsafe perception of bicycles and the status misconception of car ownership. Some neighborhood committees and shops of one of the neighborhoods were against the implementation of bike stations in specific places. However, we opened a dialogue window to clarify their doubts and share information about the benefits of a bike sharing system.Mexico City’s goal is to increase the percentage of daily bicycle trips from 1% in 2007 to 5% in 2012. The Bicycle Mobility Strategy (BMS) is an answer to the current environmental, social, economic and health crisis caused by the actual model of mobility based on cars. Its main goal is to create optimal conditions in infrastructure, equipment and cyclist culture in order to position bicycle as a viable and safe way of transport. The BMS has four strategic pillars, each of them is focused to develop specific projects: · Create a network of cyclist infrastructure, in order to generate and facilitate the cyclist’s mobility through the implementation of cyclist infrastructure (cycle paths and lanes), equipment (bicycle parking facilities) and traffic calming measures.· Make bicycles accessible to population through the public bicycle share system of the city, ECOBICI.· Promote intermodality, by providing access to destinations in less time with the implementation of ECOBICI stations near subway stations, Bus Rapid Transit (BRT) and electric powered buses stops.· Generate a culture and socialization of bicycle use, promoting recreational use of bicycle and enhancing a respect culture between road users, by recovering public spaces and implementing programs like “Muévete en Bici” (Move by bike), Critical Mass Night Rides and other programs of BiciEntrénate (Bike Training) such as Bike to work and Bike to school. In order to implement the ECOBICI system and promote bicycle use, it was necessary to change transit law, the main changes were:Hierarchy of road use (pedestrians, cyclists, motorcyclists, public transport and cars)Explanation of the new cycling infrastructure rules.Reduce speed limits in calmed areas and pedestrian zones.Transit fines for invading exclusive cycling infrastructure. The progress of the Strategy must be evaluated every year, measuring the increase in the number of bicycle trips in the city. The first annual bicycle trip measurement was realized in 2008. In 2010, the number of cyclist inside ECOBICI polygon increase 40% compared to 2009 data. Reforma cycle path became a safe, comfortable and fast corridor, where 75% of cyclists are ECOBICI users.
