Evaluation of Earliest Deadline based schedulers for reduction of traffic congestion in dense urban areas

The unwanted delay experienced by priority vehicles as a consequence of traffic congestion is one of the major problems faced while efficiently managing priority traffic. Two adaptive traffic light algorithms namely the Earliest Deadline First (EDF) and Fixed Priority (FP) have been proposed and evaluated in the paper to reduce the traffic congestion experienced by priority vehicles. The performance of the algorithms has been evaluated at isolated intersections and their resulting efficiency has been compared against a static traffic lights control implementation as well. It has been shown and deduced through different performance metrics that the overall performance of EDF is better than the FP in controlling traffic congestion for priority vehicles when evaluated against static control.
