摘要
随着城市道路网络可靠性研究的深入,交叉口已不能再作为完全可靠的道路单元,交叉口可靠性问题开始凸显。在对交叉口具体分析的基础上,充分考虑交叉口的容量限制,提出了容量限制下运行时间可靠度(TCR),并对TCR模型的优点进行了分析,给出了可接受水平值的确定方法。运用概率论基础知识,对道路网络最基本单元交叉口进行了TCR分析,给出了交叉口TCR的具体求解过程。
With the study of urban road network reliability going further, the intersection will not be considered as a reliable road unit. As a result, the problems of the intersection reliability begin to rise. Based on the analysis of the intersection, this paper takes into account the intersection capacity limitation, and brings up a concept of the travel time versus capacity reliability (TCR). Then, the paper analyzes the advantage of the TCR, and gives a method to get the value of acceptable level, At last, the solving process of TCR about the intersection is analyzed with the probability theory.
