The principal instrumentation considerations for implementing a computerized traffic control system for a diamond interchange complex are described. Such a traffic control system is comprised of a surveillance subsystem (of which the key elements are vehicle detectors), a traffic signal controller subsystem that activates the signal conditions in response to computer commands, a digital computer that receives and processes the data from the detectors and determines the best action to take based on this received data, a communications subsystem that links the computer to both the surveillance subsystem and to the signal controller subsystems, and a traffic control interface unit that serves as a buffer between the communications subsystem and the computer. The characteristics and requirements for each of these subsystems are discussed to the necessary level of detail, with the exception of the computer which has already been determined. A cost estimate for implementing this system at a given site is presented. (Author)
