The invention relates to a scene target-oriented traffic control efficiency evaluation method. The method comprises the following steps of 1) preliminarily dividing an urban traffic scene according to traffic scene characteristics, and constructing a typical scene database corresponding to a traffic scene category; 2) generating a multi-dimensional control target, and enabling the control target to correspond to the typical scene database; 3) defining an evaluation index of each control target under each typical scene library so as to construct a traffic control efficiency evaluation system based on the traffic scene large class-typical scene database-control target-evaluation index; and 4) carrying out typical scene traffic control level index calculation based on the optimized space to realize quantitative evaluation of the traffic control scheme. Compared with the prior art, the indexes constructed by the method reflect close connection with typical traffic control scenes and signal control targets, have better practical application and popularization capabilities, are suitable for comprehensive evaluation of specific scenes and overall traffic systems, and are more comprehensive, practical, accurate and effective.
本发明涉及一种场景目标导向的交通管控效能评估方法,包括以下步骤:1)根据交通场景特征对城市交通场景进行初步划分,构建对应于交通场景大类的典型场景库;2)生成多维控制目标,并将控制目标与典型场景库对应;3)定义各典型场景库下各控制目标的评价指标,以此构建基于交通场景大类‑典型场景库‑控制目标‑评价指标的交通管控效能评估体系;4)进行基于优化空间的典型场景交通管控水平指数计算,实现对交通管控方案的量化评估。与现有技术相比,本方法构建的指标反映了与典型交通管控场景、信号控制目标的紧密联系,具有更好的实际应用与推广能力,适用于具体场景也适用于整体交通系统的综合评估,更加全面、实际、准确有效。
