Intelligent Detection-Control System for Rural Signalized Intersections

摘要

Traffic engineers are often faced with operational and safety challenges at rural, high-speed signalized intersections. Vehicle-actuated control, combined with multiple advance detectors, is often used to improve operations and safety. However, this type of detection and control has not always eliminated rear-end or right-angle crashes. Crashes sometimes continue to occur at high-speed intersections, and delays to traffic movements can be unnecessarily long. This project developed and tested a detection-control system that is capable of minimizing both delay and crash frequency at rural intersections. This report documents the work performed, findings, and conclusions reached as a result of the two-year research project.
