Abstract:This research implemented the ramp management strategy (RMS) developed in a previous study, on the Black Canyon Freeway. The software system developed by Safe-Trans was modified to include the RMS algorithm for controlling the entry of ramp vehicles according to speed-volume-occupancy relationships on the freeway. Decisions on metering rates were made at each ramp location on a minute-by-minute basis and may depend on the volume, percentage occupancy and average speed on the outside freeway lane. Limited field tests were conducted to verify the capabilities of the system. This report contains the details on the RMS, Nova III computer system, ramp controllers and program listings.
