The invention discloses an urban expressway interleaving area dynamic influence range calculation method based on VISSIM simulation, which comprises the following steps: firstly, constructing a VISSIM simulation model according to design parameters of an urban expressway interleaving area and upstream and downstream road sections thereof, and selecting proper driving behavior parameters and simulation parameters; inputting different main road driving-in traffic volume data and main-main traffic volume to main road driving-in traffic volume proportion data to carry out traffic simulation, and extracting traffic flow running speed parameters of each lane on the data acquisition points; then drawing a position-speed scatter diagram under each simulation condition, and defining the influence range of each lane under the condition according to a defining method; and finally, drawing scatter diagrams of different traffic conditions and corresponding interlaced area influence ranges, fitting to obtain a function relationship, and obtaining a formula for calculating the dynamic influence range. The method for calculating the influence range of the urban expressway interleaving area under different design parameters and different traffic conditions is provided, and a research basis is provided for traffic organization of the urban expressway interleaving area.

    本发明公开了基于VISSIM仿真的城市快速路交织区动态影响范围计算方法,首先根据城市快速路交织区及其上下游路段的设计参数构建VISSIM仿真模型,选取合适的驾驶行为参数和仿真参数;再输入不同的主路驶入交通量数据和主‑主交通量占主路驶入交通量比例数据进行交通仿真,提取数据采集点上的各车道交通流运行速度参数;其后绘制各仿真条件下的位置‑速度散点图,并根据界定方法界定该条件下的各车道影响范围;最后绘制不同交通条件与其对应的交织区影响范围的散点图,拟合得函数关系,获得计算动态影响范围的公式。本发明提出了不同设计参数和不同交通状况下的城市快速路交织区影响范围计算方法,为对城市快速路交织区进行交通组织提供了研究基础。
