| 摘 要： | 本文利用混杂Petri网建模交通系统.通过分析Petri网,得到交通系统的拥塞性质,提出相对拥塞及绝对拥塞的概念,并给出相对拥塞转化为绝对拥塞的条件.结合真实交通数据,形成符合实际交通状况的Petri网实例,得到车辆分布规律,弥补现有智能交通系统仅依赖出租车GPS数据代表车辆分布情况的缺陷.

| Abstract: | Hybrid Petri net is used to model the vehicular transportation networks.By simulations on the hybrid Petri net,the properties of traffic congestion in transportation networks are obtained.Relative congestion and absolute congestion are proposed to describe two kinds of congestion state,and the condition that the state transforms from relative congestion to absolute congestion is considered.Then,real traffic information is combined with the hybrid Petri net to form an instance of the hybrid Petri net,through... |
