The Research On Risk Of Automobile Rear-end Chain On Freeway

In recent years, as people of road traffic safety attention, expressway trafficsafety accident overall presented down the number of the trend, but highway serialbehind accident the damage can’t be ignored, dozens of car serial behind collisionaccident common occurance, China central television station (CCTV-1) has reportedthe news broadcast too much on highway serial behind accident, this kind ofaccident to the people in caused heavy loss of life and property at the same time,restrict the highway play their due role huge, and greatly reduce the highwaytransportation system overall economic benefit, to the development of socialeconomy brings a lot of negative effects.Based on the highway car serial car tracing cauda phenomenon as the researchobject, the paper analyses the present situation of the development of the domesticand foreign relevant field research, on the basis of this paper put forward the maincontents combined with the traditional road traffic safety research method, fromsimple two car tracing cauda mechanism analysis as the breakthrough point begin tohighway car tracing cauda serial kind of research, through to the three kinds oftypical serial car tracing cauda phenomenon analysis to describe the highway carserial behind accident mechanism, using complexity system brittleness theory, setsup the expressway traffic system brittle structure model, and combining the fuzzycomprehensive evaluation method highway car tracing cauda risks to the series.This paper studies the purpose and aims to the rightness highway car serial cartracing cauda risk for preventing serial behind accident strategy. It shows that thesize of the entropy based on risk can measure for highway car tracing cauda risksystem serial brittle risk overall uncertainty, helps to find out what the brittlenesscollapse of the system the effect of key factors and brittleness try to control.
