基于车道级基础路网的微观交通仿真数据建模与应用研究

摘要

从满足微观交通仿真需求角度分析了仿真数据模型建模的要点，建立了包括基础路网模型、信号控制方案描述模型和交通需求模型在内的微观交通仿真数据模型。信号控制方案描述模型中，信号灯分配通行时权，信号灯组描述交叉口的通行规则。交通需求模型由交通小区和OD矩阵组成，交通小区定义OD矩阵的起终点， OD矩阵定义路网上的出行量。以VISSIM为例，研究该模型与微观交通仿真模型要素之间的对应关系，提取数据转换生成VISSIM仿真模型，论证了其用于数据提取和交换的可行性。%The requirement for data model in microscopic traffic simulation is analyzed,and the model, which is consists of basic network model,signal control scheme description model and traffic demand model,is constructed.Signal allocates access right of time,and signal groups describe access rules at intersections in signal control scheme description model.Traffic demand model contains traffic zones and OD matrix.Traffic zone delimits the origin node and destination node of OD matrix,while OD matrix de-limits volumes on the network.The corresponding relationship between elements of this model and that of microscopic traffic simulation model is studied with VISSIMas an example.Data is extracted to generalize VISSIM simulation model which proofs the model's feasibility for data extraction and exchange.
