交通流仿真系统软件设计及应用

Traffic Flow Simulation System Software Design and Application

依据车辆跟驰理论和面向对象程序设计思想,探讨了交通流仿真系统(traffic flows im u lation system,TFSS)开发中的一些软件技术,从符合我国城市交通实际的路网模型、交通流生成模型、跟驰模型、换车道模型和交叉口信号控制模型入手,采用二维动画的方式模拟车辆的运行,给出了软件设计思路、系统结构设计、主流程图、界面设计及应用,最后提出了开展混合交通条件下城市交通流仿真研究的方向。

According to the car following theory and the object-oriented program design concept, this paper discusses some software technologies in the development of traffic flow simulation system. Beginning with road network model, traffic flow generation model, car following model, lane changing model and intersection signal controlling model that accord with the actual situations of urban traffic in China, this paper uses the two-dimensional animation way to simulate the vehicles＇ movement, presents the software design idea, system structural design, host flow chart, contact surface design and application. Finally, it proposes the direction in research under the urban mixed traffic condition.
