Supply Management of Auto Traffic to Address Starvation of Green in Multimodal Environments

Traffic congestion is challenging to resolve at closely spaced oversaturated intersections. This condition leads to underutilization of green time at upstream intersections due to queue spill back from downstream traffic signals (green starvation). Such conditions cause significant delay and queue backups. In addition, conflicting modes of travel, like pedestrians or rail, may exist at a site and limit available strategies to manage the green time effectively. This project will explore strategies to increase utilization of green time that account for conflicting modes of travel. The goal is to identify strategies that are effective at reducing the number of phase failures caused by blocked street segments downstream despite limitations set by pedestrian timings or rail preemptions.
