摘　　要：交叉口作为城市道路网络的基本节点,对其实施合理的交通控制,是解决城市道路拥挤问题的关键.以信号交叉口点、线控制方式的选择为研究对象,在对4条主干路上22个交叉口进行交通调查与分析的基础上,确定出可能影响信号交叉口控制方式选择的因素.运用主成分分析法筛选得到主要影响因素,并用灰关联系数法确定各主要影响因素的权重,最后应用线性加权系数法确定交叉口点线控制方式选择的综合评价值.实例计算表明,该方法可行.Intersection is the basic node of the urban road network. How to enforce traffic control rationally is the critical to settle the problem of congestion in the urban road. The subject of the text is the choice for the signal control strategy between isolated and a sequence of intersection. The main factors which are potential to influence the signal control strategy are determined on the basis of survey and analysis of twenty-two intersection in the four artery roads, and the main factors are screened out by Principal Component Method. with gray correlative analysis, and the comprehensive evaluation values with linearity weighted aggregation. The method in this text is practical Weights of these main factors are determined of the subjected roads are ultimately acquired according to the actual example.
