This report documents the activities and results of a test of non- intrusive traffic detection technologies. Seventeen devices representing eight different technologies were evaluated in varying environmental and traffic conditions. The following technologies were tested: passive infrared, active infrared, magnetic, radar, doppler microwave, pulse ultrasonic, passive acoustic, and video. Testing was done at both freeway and intersection locations. Emphasis was placed on urban traffic conditions and locations that typify temporary counting locations. The evaluation also focused on the ease of system setup and use, general system reliability, and system flexibility.

Like previous vehicle detector research, this research tested the latest and most promising non-intrusive vehicle detector technologies. The ones included in this research were: video image vehicle detection systems (VIVDS), acoustic, magnetic, inductive loops, and microwave radar. Besides evaluating detectors, the research scope also included investigating an interface with TxDOT's current Advanced Traffic Management System (ATMS) using contact closure inputs to current Local Control Units (LCUs) for collecting vehicle count, speed, and occupancy data.
