摘要
针对重庆市常见的交通控制措施,用VC设计和开发了一套可以模拟道路通断、道路通行方向、交叉口转向规则等交通控制措施并能分析它们对道路通畅状况影响的交通仿真系统。介绍了系统的需求分析、总体设计、消息平台搭建、道路和交叉口设计、车辆碰撞检测及处理、车辆在交叉口的路径决策算法、道路畅通状态评价指标算法等问题。
Aiming at the usual traffic control measures in Chongqing city,this paper uses VC to design and develop a suit of traffic simulation system which can simulate some traffic control measures such as the opening or closing of road,direction of road,turning rule at crossing and so on,the effect of these measures to the state of road expediting can be analyzed.It introduces some problems on the system such as demand analysis,whole design,construction of message platform,road and crossing design,detection and disposal on vehicle collision,algorithm of way decision-making when vehicle is at crossing,estimating index algorithm for the state of road expediting and so on.
