多车道多车型下的环岛进口道通行能力的数学模型

Entrance Lane Capacity Mathematical Model of Multi-lane and Multi-vehicle Circle Island

随着世界各地的交通量迅速增长,环岛运行质量已面临严峻的考验,如何有效地控制环岛的交通流,改善环岛运行质量,已成为一个亟待解决的问题。我们可以利用空隙可接受理论与概率分析方法,建立多车道多车型下的环岛进口道理论通行能力模型,并对通行能力模型中的各个参数进行分析,推广已有的单一车型、单一车道理想条件下的环岛进口道理论通行能力模型。

With rapidly increasing of traffic volume all around the world, the capacity of traffic circle faces a severe test. How to efficiently control the traffic flow and improve the running quality of traffic circle is becoming an urgent problem to solve..An entrance lane capacity mathematical model for multi-lane and multi-vehicle traffic circle was established using gap acceptance and probability theory, and the parameters in entrance lane capacity mathematical model are analyzed with respect to their impacts on the Entrance lane capacity, which developed capacity theory under perfect situation which is the single-vehicle and single-lane on entrance lane of traffic circle.
