In this paper, a new ramp metering strategy is proposed. It restricts the entrance of on-ramp vehicle by space gap. The vehicle from on-ramp can enter into the main road only when the space gap on the main road is large enough. The effectiveness of the new strategy is verified by cellular automata traffic simulation model. The simulation results show that the saturated flux of the main road will be high and not drop by introducing large entrance gap restriction value. The ramp metering strategy with entrance gap restriction is effective.
Keywords:Ramp metering; Entrance gap; Cellular automata
