The objective of the Sensor for Control of Arterials and Networks (SCAN) Project previously known as Wide Area Detection System (WADS), 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 section 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 line. These measurements such as lane density, speed, and volume, would be transmitted back to the central control facility by conventional means and a set of SCAN 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. This volume documents the results of the breadboard design, fabrication and checkout phase. Details of the study phase were previously documented in the interim report No. FHWA-RD-77-85, "Wide Area Detection System Conceptual Design Study," February 1978. (FHWA)
