College campuses across the country come alive in the spring. The warm weather brings students and faculty outdoors, while end-of-the-school-year activities attract large numbers of families and visitors. With the resulting increase in walking and biking as well as vehicular traffic, the risks for campus roadway users are perhaps greater than at any other time of year. Since pedestrians and bicyclists are particularly vulnerable to traffic injuries, improving their safety is a high priority for facilities managers at colleges and universities both large and small.
