摘　　要：目前我国在道路交通信号控制的效益评价方面缺少统一标准,各地对交叉口信号控制效益的评价主要通过经验判断,缺少量化分析.首先,总结分析了国内外现有研究的各类交通信号控制评价指标及方法,在此基础上,综合选取交叉口关键车道排队长度、平均行车延误和绿灯利用率等指标,并针对高峰、平峰等不同时段的评价目标设置各项指标权重.然后,采用加权平均法综合计算交叉口信号控制效益指数,依据指数值确定对应的效益等级.最后,选取无锡市梁清路与隐秀路交叉口进行实地评测应用.结果显示,采用本文方法进行交叉口信号控制效益评价,实现了各项指标的量化分析,评价结论与实际情况较为吻合.At present,there are lack of unified benefit evaluation index and methods for road traffic signal control in China. The benefits of intersection signal control are most evaluated by the subjective judgement. Without the quantitative analysis,the conclusions of the evaluating are not scientific and reasonable. Firstly,the existing domestic and foreign research of the benefit evaluation index and methods for intersection signal control were summarized and analyzed,based on that,the indicators such as queue length of critical lane,average travel delay,and utilization rate of green light were selected to evaluate the benefit,and the weight of different indicators were determined by the control demand for different time periods,such as peak and average peak. Then,a weighted average method was used to evaluate the benefit of the signal control for isolated intersection,by which the different grades of integrated benefit of signal control were determined. Finally ,the tests were done at the intersection of Liangqing Road and Yingxiu Road,Binhu District of Wuxi City. The results show that the method is suitable for evaluating the benefit of signal control for isolated intersection,which realized the quantitative analysis of the indicators,and whose evaluation results were in good agreement with the actual situation.
