VEHICLE DETECTION. PHASE III. PASSIVE BUS DETECTOR/INTERSECTION PRIORITY SYSTEM DEVELOPMENT. VOLUME III. VEHICLE SIGNATURE ACQUISITION

Analysis and design of a successful passive bus detector cannot even begin until the characteristic features of the bus and other vehicles are known. These characteristic features are contained in the time history signals (signatures) detected by transducers located in the pavement. Three transducers were candidates for the passive bus detector: the inductive loop detector (ILD), the magnetic-gradient vehicle detector (MGVD), and the magnetometer. Early analysis eliminated the magnetometer from the candidate list. A total of 450 signatures were acquired from the ILD and MGVD from various vehicle types and test conditions. These signatures depicted all necessary feature data for the vehicles and test conditions, and allowed for subsequent analysis, design, and demonstration of a successful passive bus detector.
