摘要
道路交叉口是城市道路网络中的节点。交叉口布置型式是否合理,交通渠化是否恰当,不仅影响到城市交通是否畅通,并且与道路交通安全密切相关。以城市发展中遗留Y型交叉口改造为例,分析交叉口渠化设计方案,并通过交通量预测结果对交叉口通行情况进行仿真分析,为方案选择提供依据。
The road intersection is the node in the urban road network. The reasonable intersection arrangement and the appropriate traffic channelization not only affect the smooth flow of urban traffic,but also are closely related to the road traffic safety. Taking the reconstruction of a Y-type intersection reserved in the city development as an example, this paper analyzes the design scheme of intersection channelization, and simulates and analyzes the traffic status of intersection through the forecast result of traffic flow in order to provide the basis for the selection of schemes.
