Pedestrian Friendly Traffic Signal Control

This project continues research aimed at real-time detection and use of pedestrian traffic flow information to enhance adaptive traffic signal control in urban areas where pedestrian traffic is substantial and must be given appropriate attention and priority. The hypothesis investigated in this work is that lower resolution vehicle detection camera technology can be used to provide a relaxed form of pedestrian count data that is sufficient for incorporating pedestrian flow information into real-time intersection scheduling. Specifically, the authors study the possibility of extracting an approximate but usable measure of pedestrian “density” from the video stream of a commercial traffic camera. The target functionality is the ability to qualitatively discriminate between “no”, “few” or “many” waiting pedestrians.
