基于灾害蔓延理论的拥堵传播建模与仿真
Modeling and simulation of congestion propagation based on disaster spreading dynamic model
摘要
Abstract
The model of congestion propagation in urban rail transit network based on disaster spreading dynamic was established, and the rule of congestion propagation was revealed, providing fundamental basis of rail transit operation. Firstly, the applicability of disaster spreading dynamic in urban rail transit network was described. Secondly, the congestion process and features in urban rail transit network were analyzed. Then, the congestion propagation dynamics model was established based on the disaster spreading dynamic model, and train load factors were defined as node property. The simulation experiment conducted from four aspects, including node type, initial risk value, node risk threshold and self-repairing capability. The research shows that the congestion propagation dynamics model in this paper can reflect the process of the congestion propagation, and reveal propagation rule in urban rail transit network. The conclusion can provide some academic bases and references for congestion control and transportation organization.关键词
