WIDE AREA DETECTION SYSTEM Conceptual Design Study

摘要

The objective of the Wide Area Detection System (WADS) Project is to determine the technical feasibility of using state of the art imaging (such as television) and processor (such as microprocessor) technology to build an integrated sensor for traffic surveillance on mainline sections of urban freeways. This sensor would be capable of automatically making "area" measurements, i.e. across several lanes as well as along the traffic stream in each lane. These measurements, such lane density, speed, and volume, would be transmitted back to the central control facility by conventional means and a set of WADS sensors would thus be deployed to cover the entire length of the freeway. The freeway image would also be used for surveillance and incident diagnosis. The WADS project consists of two phases: first, a conceptual design study and second, building a "breadboard" operating sensor.
