In May 2009, a team of 12 transportation professionals with expertise in bicycling and walking from the U.S. visited five countries in Europe to identify and assess effective approaches to improve pedestrian and bicyclist safety and mobility. Some of the countries, like Denmark, had experienced an increase in car use in the 1960s and 1970s, and subsequently reoriented their transportation policy to give priority to bicycling and walking. The scan team heard presentations from and had informal discussions with the foreign hosts. During most visits, the scan team also went on guided field visits (by bike as well as by foot) to better understand and experience the design and operation of various walking and bicycling facilities. These field visits were invaluable in documenting the facilities through photos and video, observing traffic behavior, and experiencing firsthand how well a design or operational strategy worked. The purpose of this scan tour was to identify and assess effective approaches to improve pedestrian and bicyclist safety and mobility.
