Critical Boundary of Delay Spread on Urban Road Traffic Network under Disruptive Traffic Accidents
摘要
Abstract
Critical boundary of delay spread provides basic theoretical guidance to prevent the large areas delay of urban road traffic network caused by the disruptive traffic accidents.The SIS model of delay spread in the road traffic network is built by applying mean-field theory.The analytical expression of critical value of delay spread is obtained by the steady state density of the delay sections in the steady state system of the SIS model.Moreover,the simulation system is designed to test on the critical value of the delay spread on the generated virtual network "with the same statistical characteristic as the topological structure of road traffic network".The simulation results coincide well with the analytical results.The study shows that the critical value of the delay spread in the urban road traffic is inversely proportional to "the traffic volume of the road traffic network,the average degree of the network,the average number flowing through the sections of the traffic flow in unit time,and the total traffic volume in the network and probability of rechoosing roads",and it is in direct proportion to the network sections number.关键词
