为研究城市群连接道路规划与设计方法,从城市群连接道路的功能出发,对城市群道路进行功能分级,确定了设计控制指标,提出了适合城市群交通特征的规划方法。基于城市群道路功能分级和区域交通时空特性,借助VISSIM仿真模型,分析了城市群连接道路横断面设计参数及设置形式。研究结果表明:按照道路功能分级,城市群连接道路可划分为城市群高速公路、Ⅰ级连接道路、Ⅱ级连接道路、Ⅲ级连接道路、地方道路;在满足车辆行驶的横向宽度条件下,交通组成对路段平均车速和通行能力的影响较大。
In order to study the planning and design method of urban cluster connecting roads, the function of urban clusters connecting roads is graded, the function of urban cluster roads is graded, the design control indexes are determined, and the planning methods suitable for urban cluster traffic characteristics are proposed. Based on the classification of urban road functions and the spatial and temporal characteristics of regional traffic, the VISSIM simulation model is used to analyze the design parameters and the forms of the cross-section of urban agglomerations. The results show that according to the grading of road function, the connecting road of urban agglomeration can be divided into urban expressway, grade Ⅰ connecting road, grade Ⅱ connecting road, grade Ⅲ connecting road and local road. Under the condition of satisfying the lateral width of traffic, The composition of the average speed and traffic capacity of the greater impact.
