摘要
针对交通节能减排问题,运用计算机仿真技术和视景仿真技术,搭建一个面向环保评估的城市微观交通流仿真模型.该模型主要由出行需求模型、路网描述模型、交通规则模型、信号灯控制模型、车辆行为模型、动态路径选择模型和机动车排放模型组成.在对模型进行标定和验证的基础上,采用面向对象开发环境VC++6.0及实时视景仿真工具Vega进行了原型系统开发.最后,选取武汉市典型路口路段进行交通环保仿真评估,取得了较满意的结果.
An urban microscopic traffic simulation model was established through computer simulation and visual simulation, which consists of seven models： traveler demand model, network describing one, traffic regulation one, signal control one, vehicle behavior one, dynamic route choice one and vehicle emission one. After the model was calibrated and validated, an urban microscopic traffic simulation system was proposed. In this model, the programming language Visual C＋＋6.0 and real-time visual simulation tool Vega were used. A typical road net in Wuhan city was chosen to evalue environmental protection. Compared the simulation result with the field data, they are satisfied.
