中文摘要：

讨论了协调控制方案评价时流量因素的重要性，提出了以仿真手段为基础的干线协调控制方案的交通效益分析指标，该指标可用于分析协调控制方案对流量变化的适应性和敏感性．实验结果表明该指标具有可行性．通过分析绿信比变化、协调交叉口数量的变化对协调控制交通效益的影响，获取了协调控制方案的某些一般性特征，如干线方向的最小绿信比对整体交通效益起决定性影响；协调交叉口数应少于7个．

英文摘要：

This paper discussed the importance of flow factor in evaluation of artery coordinated control, and then proposed an analysis index for artery coordinated control based on traffic simulation, which could be used to analyze the adaptability and sensitivity of coordinated eontrol plan when flow was changing. Preliminary experiments showed its feasibility. After analyzing the coordinated benefit at different splits and different numbers of coordinated intersections, some general characteristics of coordinated control were obtained that minimal split in artery direction will influence the whole coordinated control benefit greatly and intersections in coordinated control should be less than seven.
