BENEFITS OF CENTRAL COMPUTER CONTROL FOR DENVER RAMP-METERING SYSTEM

An evaluation was made to determine the effects of providing central computer coordination on the Denver ramp-metering system. Information from the system was collected with the coordination algorithm operational and with it disabled. The data suggest that, when local demand-responsive ramp-metering control is unable to maintain freeway speeds at or near the posted limit of 55 mph, central coordination can be useful in reducing main-line delays. However, when speeds are near 55 mph with local ramp metering in operation, central coordination of the type used in the Denver system may be of little benefit.
