Highway Tunnel Traffic Incident Control And Decision Support

The research of this paper relies on The transportation science and technology projects construction in western -- " Highway tunnel And Tunnel Group Security Management study "Which is the 5th sub-topic ofVehicles" Movement Safety control Engineering research of Highway tunnel And Tunnel Group" .The safe of highway tunnel due to many kinds of factors working together that will lead to all kinds of traffic incident. Traffic incident has brought driver's life,property and social wealth huge losses. For the tunnel traffic incident the decision-making techniques rely on traffic police and the tunnel management staff's personal experience now. which rely on human experience to conduct a traffic incident management, it is difficult to widely use, but also to the entire road network in the complex and dynamic' traffic make scientific decision-making on time and accurate will more difficulty.As the traffic characteristics of the highway tunnel and investigation information of the accident in the highway tunnel, under the special environment poses risk of traffic accidents and traffic accident risk analysis of the consequences will be unified in the highway tunnel traffic by the risk models. Analysis of the risks associated with highway tunnel traffic accident risk factors and the relationship between the comprehensive consideration the development of risk occurrence and risk factors, establish index system, based on real-time dynamic traffic information study highway tunnel traffic accident risk analysis. Highway tunnel through the division of operational real-time risk level for the prevention control of the road tunnels and decision-making.Analysis of events to study the effects of radiation incident tunnel traffic, traffic incident duration of the influencing factors, traffic delay, give a tunnel traffic accident incident database structure easy to in-depth analysis. On this basis, analysis the factors affecting the delay time of the traffic incident .By rough set theory, using C + + and the rough set tools of Rosetta platform combined to predict traffic incident delay time, in the case analysis, in accordance with the impact on traffic delay time characteristics of the incident for rough decision table ROUSTIDA data padded algorithm proposed improvements.Study the vary degrees traffic incident in different section of the tunnel area, take place a state of the tunnel rescue routes and evacuation routes combined Traffic Organization and Control Program, under the proposed regional road network traffic incident model for coordination and control. The management of the tunnel for the highway department's traffic incident management decision support.
