Analysis of On-Ramp Metering Strategies on Urban Freeway Based on Capacity Constraints

This paper, combining with the on-ramp metering principle and goals, theoretically analyzed the importance of effective on-ramp metering as to improve the efficiency and service level of the freeway system. Then three control processes of timing control, merging control and no control are expounded in detail. By using VISSIM simulation tool, the curve figures of the relationship among different traffic parameters are given for the entrance ramp that does not have enough queuing space. The paper also compared the advantages of the three control strategies. Finally, regarding of the limited ramp capacity, some other supplementary measures to alleviate the congestion are put forward.
