One critical issue of traffic control is the optimization of signalized intersections for improved
multimodal safety and operations. Accommodating pedestrian traffic at intersections is
challenging because the demands of multimodal service compete fiercely on limited green
time resources. The Highway Capacity Manual prescribes that the parallel vehicle green
must exceed “Walk” plus pedestrian clearance interval (PCI) timed by a design walking
speed. This static PCI timing is unsafe because seniors and children are likely to be slower …
