Lace up your walking shoes. Tune up your bicycle. Ditch your keys. Today is World Car Free Day.

The global event to reclaim streets from the automobile has been building momentum since it launched in Toledo, Spain 16 years ago.

Network blog The City Fix is offering a glimpse of what different cities throughout the world are planning to reassert people’s right to the road:

Austria:  Seven cities will compete to see which type of transportation – bike, mass transit, car, bus – is fastest in each city.

Shanghai, China: In an improvement from last year, seven square blocks around the Shanghai World Expo will be closed to car traffic.

Curitiba, Brazil: Will host a “tweed ride.”

Chicago, U.S.A: Events include bike rodeos, rallies and a meeting of bikers who have been hit while bicycling.

And World Streets, in addition to carrying a thorough history of the event, is offering some inspiration for those who are trying to make a difference in a car-dominated environment.

Rarely are there single persons or groups who all by themselves make the difference. Rather there is this slow, often irritatingly slow, cumulative process of assimilation of ideas, attempted actions, not all of which crowned by immediate success, and changing perceptions which occasionally combine, here and there, to change first attitudes and then, with any luck at all, some of the salient and important choices that we all make together which shape our daily lives, and those of our cities.

The most basic action a person can take is to simply see what it’s like to live without a car. Do you know anyone who’s foregoing driving to celebrate World Car Free Day?
