Supply-Side Management of Auto Traffic

Many traffic signals frequently experience oversaturated conditions. Such conditions cause significant delay and queue backups. When traffic signals are closely spaced, queues from downstream signals can back up to upstream signals. Such a scenario can result in starvation which is a phenomenon when queues from a downstream bottleneck prevent full utilization of upstream green phases This project will entail synchronizing green phases across neighboring traffic signals to the backward waves that propagate through queues. The goal is to ensure that green phases are displayed only after queues recede on street segments downstream. In this way, traffic movements are not blocked when they receive green signals.
