Improving Walkability Through Control Strategies at Signalized Intersections

Sirisha Kothuri

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...
