Abstract:
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.
