VEHICLE DETECTION - PHASE III. PASSIVE BUS DETECTOR/INTERSECTION PRIORITY SYSTEM DEVELOPMENT. VOLUME I. PROJECT OVERVIEW AND TECHNICAL DISCUSSION

The Passive Bus Detector/Intersection Priority System was developed under this project. The system functions as a fully independent traffic controller with completely passive bus detection capability using inductive-loop detectors (ILD) placed in the roadway. Bus detection is based on ILD signal processing (classifier) techniques, thereby eliminating need for any modifications or additions to the bus. Passive bus detection hardware includes special ILD electronics, a high-speed programmable processor, and a microprocessor. Using the same microprocessor, plus programming panel, stored programs, and switching and safety units, the system design is sufficient to exercise bus priority control at urban intersections containing up to 23 signal circuits and 16 ILD transducers. In addition, the system has capability of commanding the traffic signals in either one of three fixed timing patterns, selected at the system by the traffic engineer or controlled by a loop master.
