The Car Free Alliance have produced an excellent toolkit for groups. You can find it on their website www.carfreealliance.org/toolkit.
The toolkit is an organized collection of information, advice, ideas bank, how-to’s and more, designed to guide groups in running car-free related campaigns, projects, events and programs. From traffic-calmed streets, to pleasant neighborhoods and all the way to carfree cities, the toolkit is an excellent resource to browse if you’re thinking of running any kind of campaign aimed at reducing levels of car use.
