World Car Free Day is celebrated on September 22, 2017. A Car-Free Day encourages motorists to give up their cars for a day. Organized events are held in some cities and countries. The event promotes improvement of mass transit, cycling and walking, and the development of communities where jobs are closer to home and where shopping is within walking distance. The events, which vary by location, give motorists and commuterists an idea of their locality with fewer cars.
The 1994 Car Free Day Call set out a challenge for a city, neighborhood or group: Spend one carefully prepared day without cars, study and observe closely what exactly goes on during that day and reflect publicly and collectively on the lessons of this experience and on what might be prudently and creatively done next to build on these. Car-Free days are held in many U.S. cities, in Europe and in Japan. (With material from: Wikipedia)
