Self-Organizing Traffic Signals

Abstract

Efficient traffic signal control is a key to increase roadway capacity, reduce delay and roadway footprint. With transit signal priority (TSP) and short cycle lengths, it can promote the operation of public transportation and walking, thereby reducing auto-dependency. However, existing signal controllers are typically limited in their ability to respond to variations in traffic demand and recover from priority interruptions, therefore ill-suited to TSP. Our objective is to develop traffic signal control algorithms which are free of any cycle length, yet still have coordination mechanisms through communication between neighboring intersections, making them
