The report presents the results of developing a computerized analytical technique which could determine the optimum metering rates for a group of on-ramps. Need for a freeway model and a decision model is identified. An existing freeway model is described and its application to the problem of ramp control, when no decision model is available, is discussed. Two linear programming decision models, based on two different traffic diversion assumptions, are formulated and a computer program is prepared. The freeway model and the decision models are than integrated into a single computer program. The user can select either maximizing total input or maximizing total vehicle-miles as the objective. Problems related to the applications to fixed-time control are discussed. A traffic-responsive control logic which is efficient on a short-term basis and stable on a long-term basis is presented.
