摘要
提出了一个道路交通网络运行效率的定量评价方法,由此计算的效率评价指标能综合反映网络中交通需求、路段流量、旅行负效用等因素对交通网络效率的影响。同时基于该评价方法,设计了一个网络组件的重要度评价方法,该方法计算简便,且评价结果具有一致性。算例计算分析的结果验证了本文效率评价方法和重要度评价方法的合理性,而且上述评价方法还说明了交通拥挤网络的效率和组件重要度,均与网络中当前交通流量有关。
A quantitative evaluation method for lhe road transportation network efficiency was proposed to grasp the effects of the traffic demand, the sectional traffic flow, and the travel side-effect,etc. , on the network efficiency. Based on this method, a method for evaluating the importance level of the network components was developed to distinguish the important modes and links in the network. The method has been vesified by a practical example and is characterized by the simplicity of calculation and the agreement of the calculated results with the practical data. It was found that the network efficiency the network component importance level are related to the traffic flow in the network.
