摘要
上海某交叉口首先运用"冲突点法"进行信号配时设计,然后针对该路口的实际情况,提出了一种新的交通组织方案:在不进行大面积施工的情况下,增设独立的左转车道,使原先的二相位信号控制转变为四相位信号控制,从资源上增加路口通行能力.评价结果表明,该方案切实有效,可为提高城市道路交叉口通行能力、缓解交通拥堵提供参考.
Signal timing at an intersection of Shanghai was designed by ＂conflict spot＂method.Then according to the practical situation of the intersection a new scheme changing two-phase signal control to four-phase signal control by setting a left turn lane was proposed to increase traffic capacity of the intersection.The result proves that this scheme is effective,which may be as an academic reference for improving traffic capacity and alleviating traffic congestion.
