Signalized intersection is the junction of traffic flow in the road network,which is the key to ensure the smooth urban traffic.In order to solve the problem of single evaluation of urban arterial signal control scheme,a comprehensive index system was constructed oriented to traffic efficiency,traffic safety and traffic environment.Besides,combined weighting-fuzzy comprehensive evaluation model(FCE)steps model were utilized to carry out comprehensive evaluation of urban arterial signal control scheme.Based on three signal control schemes of Xinghua street arterials in Taiyuan,the required evaluation index values were obtained by using VIS-SIM and surrogate safety assessment model software simulation,and the comprehensive score values of the three schemes were calculat-ed.The results indicate that they are consistent with the actual results basically,which verify the effectiveness of the evaluation sys-tem.The research results of this paper provide a theoretical basis and technological support for the preliminary planning and manage-ment of urban arterial signal system.
