3-66 Signal Transition Logic - Phase II

completed

This research project will implement the National Cooperative Highway Research Program (NCHRP) research 3-66 signal transition logic into a real-world, advanced transportation controller (ATC). Signal transition logic uses dynamic programming algorithms to choose the next series of signal states to arrive in a desired state to minimize both delay and other criteria when faced with unusual traffic sensor inputs such as trains, fire trucks, police, ambulances, funeral processions, and tractor trailers. Current technologies only allow nonoptimal processing of these items as preempts.
