The second part of the proposed program, which is known as the Bogota Project, requires the parallel development of a massive and far-reaching overhaul of the city's transportation system, to permit those who ilive and work there to have a very high level of access as well as a cleaner, quieter, safer and more just city.

The referendum also included a second proposal about establishing the celebration of a Car Free Day once a year, as of the year 2001, every first Thursday of February in Bogotá. Car circulation would be prohibited on this day from 6:30 a.m. until 7:30 p.m. This section of the site provides useful background on the referendum, its results and the long term projects and programs behind it.
