摘要:

本文提出了一种新的AD-ALINEA与匝道排队长度相结合的匝道控制方法。在AD-ALINEA基础上,兼顾入口匝道排队长度对整体路网交通的影响,将匝道调节率取为AD-ALINEA和排队控制所计算出的调节率的最大值。通过元胞传输模型对ALINEA、AD-ALINEA及本文新方法进行仿真,并对三种方法的主路下游流量及匝道排队长度进行比较分析。结果表明,新方法能够明显降低匝道排队长度,又能保证主路下游流量,同时兼顾了整体路网的效率与公平。

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
