Feasibility of Using Video Image Detectors for Ramp Signal Operations and Performance Monitoring

This project will investigate the feasibility of using a video detection system to collect performance data, such as queue length and delay, in addition to vehicle volume and occupancy that are currently being detected using traditional inductive loops and sensors. The project will survey existing video detection systems and invite three for field tests at an actual ramp signal location. Based on the test results and other considerations including costs, maintenance requirements, and ease of integration, the project will recommend an existing video detection system that can be immediately implemented. This project will further develop a web-based system for calculating and visualizing performance data for monitoring and analysis.
