摘要
复合交叉口渠化设计对于提高交通服务水平,保证交通安全,解决城市交通拥挤问题有非常重要的意义。以泰州一典型复合交叉口为例,通过多方案的设计及比选,提出了复合交叉口渠化设计的思路、程序和方法,并对所选择的设计方案进行了仿真测试,结果表明所选择的设计方案优于其他备选方案,改善了原有交叉口交通流的紊乱现象。文章所提出的方法对此类交叉口的设计提供了一个参考。
It＇ s very important to do traffic channelization design for complex intersection, improve traffic service level, guarantee traffic safety, and solve urban traffic jam. The paper proposes some ideas, procedures and methods for traffic channelization design of complex intersection through a design illustration of a complex intersection in Taizhou city. First the intersection traffic condition was analyzed, and then in order to give a reasonable channelization design, three design scenarios were put forward, Iintersection capacity and service level were computed out to evaluate and compare the effect of the three channalization design scenarios. At last the second design scenario was proposed to be the chosen design and a traffic simulation was carded out. The result shows that the chosen design scenario greatly improves the intersection traffic condition and capacity. The traffic channelization design method advanced by the paper can be a reference to deal with the same type intersection design,
