Pedestrian/Road Worker Visibility
In 1999, over 5,600 pedestrians and pedalcyclists were killed in the United States and 136,000 were injured. Worldwide, rates are much higher, especially in developing countries. To mitigate this problem, UMTRI researchers study the visibility of pedestrians, bicyclists, and roadworkers both in daylight and at night. Studies investigate the effectiveness of retroreflective materials and the distances at which pedestrians can be seen.
