摘　　要：信号协调联控是缓解城市主干线交通拥堵、提高道路通行能力的有效手段。针对干线信号协调联控中支路方向通行效率较低的问题,提出了一种面向区域的信号协调联控方案,并以太原市某一区域为例,利用VISSIM软件输出总延误判别优化仿真结果。研究结果表明:实施区域信号协调联控,可以有效提高道路的通行效率,降低主干线和支线的总延误。研究有助于为城市干线的系统规划与运营提供借鉴。Signal coordination is an effective method to alleviate traffic congestion and improve road capacity on urban traffic arterials.However,there is also room for improvement in signal coordination control.Aiming at the low traffic efficiency in minor arterials,the paper proposes a program of regional signal coordination and joint control.VISSIM software is used to simulate road conditions in a certain part of Taiyuan City and calculate the total delay under the program to differentiate optimal simulation results.Research results show that regional signal coordination and joint control can effectively improve traffic efficiency and reduce total delay of major and minor arterials.The study may provide some reference for systematic planning and operation of urban traffic arterials.
