摘要:

平面交叉口是路网的瓶颈点,拥堵和事故往往聚集发生于交叉口处,因此对瓶颈点进行系统性的研究非常有必要。本文在城市更新的背景下,以苏州工业园区文景路-林泉街交叉口为例,研究道路往右侧拓宽场景下的直行车道的交通运行情况,发现交通在横向车道上的分布存在不均衡性,对通行效率的影响较大。基于安全和效率的研究目标,通过既有设施的交通组织优化措施,提升节点的服务品质。

Abstract:

The level intersection is the bottleneck point of the road network. Congestion and accidents often occur at the intersection. Therefore, it is necessary to systematically study the bottleneck point. In the context of urban renewal, this paper takes the intersection of Wenjing Road and Linquan Street in Suzhou Industrial Park as an example to study the traffic operation of the straight lane when the road is widened to the right. It is found that the distribution of traffic in the lateral lane is uneven. , which has a greater impact on traffic efficiency. Based on the research goals of safety and efficiency, improve the service quality of nodes through optimization measures of traffic organization of existing facilities.
