Bicycling in Munster

Bicycling is a frequent activity in Munster. About 43 percent of trips are by bike and 48 percent are by car, which is a very high percentage of bike travel compared to most German cities. The city has an advertising campaign (poster and postcards) to compare the space used by various modes of travel and the advantages of using public transit and bicycling. The campaign compared the amount of space needed to transport 72 people with the following statistics:

* Bicycle: 72 people are transported on 72 bikes, which requires 90 square meters.
* Car: Based on an average occupancy of 1.2 people per car, 60 cars are needed to transport 72 people, which takes 1,000 square meters.
* Bus: 72 people can be transported on 1 bus, which only requires 30 square meters of space and no permanent parking space, since it can be parked elsewhere.
