Abstract:

A new on-ramp metering method combining AD-ALINEA with ramp queue length was proposed in this paper. Based on AD-ALINEA, when the effect of onramp queque length on overall road network is taken into account, ramp flow is given by the maximum of AD-ALINEA and queque control. New method was compared to ALINEA and AD-ALINEA by using Cellular Transport Model (CTM), downstream flow and ramp queue of the three methods were analyzed. The simulation results show that new method can significantly reduce on-ramp vehicle queue length, and ensure downstream flow. At the same time, the efficiency and fairness of overall road network are both considered by the new method.

Key words: freeway, cellular transport model, AD-ALINEA, on-ramp control
