摘　　要：在桂林,伴随着福利路的开通,使该城市北方路网逐步完善,但随之带来了与日俱增的交通压力。交通拥堵造成交叉口服务水平低下,本着缓解城市交通拥堵的目标,在桂林市选取圣隆路,北极广场及其周边区域,对区域内各交叉口进行交通基础数据调查,针对关键节点问题,分析其症结所在,对圣隆环岛提出是否拆除环岛的两种渠化方案,并结合四色原理进行配时设计。对环城北一路-圣隆路T型交叉口提出机非分离与提前分离右转车辆两种渠化措施,并重新规划信号相序。最终通过VISSIM仿真分别对两个交叉口的两种设计方案进行评价,从安全、经济、环境等角度进行方案比选,选定最佳方案。In Guilin,along with the start use of Fuli road,the northern road network of the city has been gradually improved,but the traffic pressure has increased with each passing day.In order to alleviate the traffic congestion,we selected Shenglong Road,Arctic Square and its surrounding areas in Guilin to investigate the basic traffic data of the intersections in the area.Aiming at the key node problems,we analyzed the crux of the problem and proposed whether to dismantle the ring or not.Two canalization schemes of the island were designed in combination with the four-color principle.Two channelization measures were proposed for T-intersection of Huancheng North Road-Shenglong Road,i.e.non-separating and separating right-turning vehicles in advance,and the signal phase sequence was re-planned.Finally,the two design schemes of the two intersections were evaluated by VISSIM simulation,and the schemes were compared from the angles of safety,economy and environment.Finally,the scheme was selected.
