September 22 is World Car Free Day. According to The Washington Post, 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". Studies showed that for short trips in cities, one can reach more quickly using a bicycle rather than using a car.
In the Chicago area, the Regional Transportation Authority (RTA) and their service boards, CTA, Metra, and Pace, often have events or campaigns to encourage commuters to consider alternatives to driving alone. Watch the TMA’s website for updates on this event.
