Research On Reliability And Network Traffic Organization Of Emergency Events

Emergency events leading to road traffic is blocked, the highway transportationinfrastructure reliability is not high, the essential features of emergency: a randomevent, regardless of traffic management personnel or personnel on the location of theevent, driving time, are unable to accurately predict the impact; two is a disruptive event onthe normal traffic operation the event, will cause a temporary increase in road capacitydecline or traffic demand, will lead to traffic congestion, congestion, accidents, trafficflow and environment will bring the very big destruction. Therefore, it is necessary for theevent of an emergency network Emergency Traffic Organization research.Transportation planning and management related problems in the event of an emergencyas the research key, first analysis of emergency risk, through the analysis of the impactof emergencies on traffic, establish the risk evaluation index system, to determine theweight of each index on emergency hazard was calculated and the emergency level division,from the network the average speed, traffic congestion and road network connectivityreliability three aspects of emergency road network operation; influencing factors throughthe analysis of road network connectivity reliability, research the relationship betweenemergency and network stability, determine the evaluation of road network reliability indexand road network reliability; by determining the content and methods of survey dataacquisition objective and the investigation of traffic organization, basic data analysis, andthen put forward the concrete steps of traffic organization; study the traffic guidance andtraffic control measures, followed by the study of emergency traffic organization methodfor downhill traffic accidents and interchange at the traffic accident, traffic accident growtunnel emergency, the emergency security system emergency building.
