【摘要】 交通流诱导与控制是解决现代交通难题的有效手段,根据Internet分组流管理的基本思想,研究了城市路网交通流的诱导与控制。从4个主要方面比较了交通流与分组流的相似性,从而证明了把后者的理论应用于前者的可行性。介绍了分组的路由算法和拥塞控制策略,提出并举例说明了动态诱导路径的分区分层算法,交通拥塞控制的分布式交通量均衡方法。实践证明了这一方法应用于交通流的诱导和控制是可行和有效的。更多还原

【Abstract】 Guidance and control of traffic flow is a valid way to solve modern traffic problems.This paper studied the guidance and control of the traffic flow in city road network based on the theory of data packet flow in Internet.Similarity between the traffic flow and the packet flow was analyzed on the four main aspects.The feasibility to apply the theory of the latter to the former was testified.A packet routing algorithm and jam control tactics were introduced.The regional and gradational algorithm for dynamic guidance paths,and the method of equalizing the traffic volume to relieve traffic jam were set forth and illustrated.Success on Internet proves that they are feasible and effective for guiding and controlling traffic flow.更多还原
