【摘要】 畸形交叉口是城市交通网络瓶颈,也是交通事故频发的黑点。交通组织是治理畸形交叉口的有效方法。在一些畸形交叉口的实际运行情况中,常规相位配时已经体现极大的局限性。针对此种情况,引入组合相位的概念,在此基础上对组合相位的优化原理、特点作进一步的论述分析,并指出组合相位的适用情况。最后利用组合相位对畸形交叉口内的各股交通流进行配时设计,通过实例反映出组合相位相对于常规相位的优越性。更多还原

【Abstract】 Traffic control is an effective approach to im- prove the status of deformed intersection.In this essay, through analyzing the limitation of the existing regular phase that is set up for the deformed intersection in practice and,therefore introduce the concept of combi- natorial phase.Furthermore,there will be a further analysis of the combinatorial phase’s characteristics and optimi- zation principles,and the implementation of the combi- natorial phase will be indicated subsequently.Finally, the various streams of transportation in deformed inter- section would be timing-designed with the combinato- rial phase.And,by illustrating samples,the superiority of the combinatorial phase comparing with the regular phase would be reflected eventually.更多还原
