Vehicle Detector Placement for High-Speed,Isolated Traffic-Actuated Intersection Control. Volume 3. Case Study:Local Field Test and Evaluation.

摘要

The study was undertaken to improve understanding of how to place vehicle detectors at high-speed (at least 35mph),isolated,traffic-actuated intersections,and how to test and evaluate alternative detector/controller configurations for intersection traffic safety and efficiency. A definitive before/after field test was conducted at two high-speed,isolated,traffic-actuated intersections in Kentucky,using each intersection as its own control. An advanced form of detection was found to substantially and reliably reduce the incidence of traffic conflicts compared to conventional signalization. Methodology and statistical results are described in detail within this volume.
