Abstract
Some streets in Washington are to become a test site for trying new traffic control strategies. Surveillance (detection of vehicle presence and estimation of traffic conditions from this information) is an important function of this test site. Equipment required for the surveillance task includes vehicle detectors, communication and a digital computer. This paper is limited to a discussion of the surveillance aspects of the test site, and background information on design and performance of existing computer-controlled traffic system is provided by the list of references.
