摘　　要：针对当前城市发展过程中老城区用地受限且交叉口交通拥堵的现状,提出如下交通微改善策略:一是从工程层面压缩侧分带、取消路侧停车来渠化交叉口;二是从管理层面进行路口交通管制来保证主流向的通行效率;三是优化交叉口信号控制方式;四是迁移公交站台或外置左转车道来增加交织长度。选取一个交叉口为案例,结合VISSIM软件仿真,对比交叉口微改善前后交通质量。为老城区交叉口交通微改善策略选择提供了一个有效的技术路线。Aiming at the intersections with limited land usage and traffic congestion in the old town during the current urban development process,the following traffic improvement strategies are put forward.The first is to channel the intersections by compressing the lateral zoning or canceling the roadside parking at the engineering level.The second is to carry out traffic control at intersections to ensure the traffic efficiency in the mainstream direction at the management level.The third is to optimize the intersection signal control mode.The fourth is to transfer the bus stop or the external left-turn lane to increase the interweaving length.Taking an intersection as an example and combining VISSIM software simulation,traffic quality before and after slight improvement at the intersection is compared.This paper provides an effective technical route for the selection of traffic micro-improvement measures at intersections in the old town.
