abstract="A procedure has been developed for predicting the self-assignment of time-varying traffic demands in a network. The procedure's computer program, CORQ, has been used to validate and apply the model in a real corridor. It is intended as a tool to enable the traffic analyst to assess the systemwide effects of any traffic-control strategies proposed for a network as long as the total system's demands remain invariant or at least have a predictable response to the controls. The model has been specialized to give detailed treatment to the critical elements of a corridor that affect traffic flow, capacity, queuing, and delays. It can be used for a form of microanalysis of areas that are about 500 blocks large. For these cases it considers only the major intersections, freeway interchanges, and their surface-street links but gives them a detailed treatment. It can be used for much larger areas if only the freeway network needs to be modeled. Time-varying traffic controls can be simulated. CORQ also can serve as a partial optimization technique by selecting metering rates that fully use the capacity of a merge without queuing on the freeway. CORQ is intended for use in estimating quantitatively the effects of various types of traffic control strategies before a commitment to any specific control schemes and installation of specialized hardware. It can serve as a traffic-management game, and it has been used in training students in the design of traffic-engineering and traffic-control schemes including ramp closure, ramp metering, restriping, and altering traffic-signal splits.<p />",
