Research Highlights

Enhancing Bicycle and Pedestrian Education through Curriculum and Faculty Development

Lynn Weigand
Since the passage of ISTEA in 1991, the amount of funding for and attention to bicycle and pedestrian infrastructure has increased significantly (Federal Highway Administration, 2009) and communities are focusing more attention on these modes of travel. These factors have increased the need for planners and engineers to possess more skills and knowledge related to bicycle and pedestrian planning and design. However, there is a lack of relevant curriculum, faculty interest and faculty suppor... Read More

Improving Walkability Through Control Strategies at Signalized Intersections

Christopher Monsere
Edward Smaglik
The goal of signal timing at an intersection should be to separate conflicting movements in time, maximizing safety and efficiency for all users. In many jurisdictions, however, signal timing objectives have traditionally focused on allowing vehicle progression and reducing vehicular delay and stops. While these are important considerations in many contexts, other users (especially pedestrians) deserve similar focus and control strategies. Recent updates to the Highway Capacity Manual (HCM 20...
