Urban Trunk Road Traffic Emergency Road Impact Analysis And The Traffic Organization Research

With the development of Chinese economy, the urbanization process is accelerated, and the rapid growth of urban population, resulting motor vehicle ownership becoming more.The construction speed of urban road has been difficult to meet the demand of urban residents of normal traffic. At present, different kinds of emergencies seriously endanger people’s life and property safety, even the healthy development of the city in future. So the research of emergencies’ theory and method has become the most important. As the most frequent incidents, urban traffic incident has a sudden strong destructive characteristics, especially the road traffic incident, and has had a huge impact to People’s Daily and the operation of the urban traffic system. In order to more scientific and effective to deal with emergencies, it is necessary to carry out the theory analysis and emergency organization research on urban trunk road traffic.The research topic of the paper is urban trunk road traffic incident emergency traffic impact analysis and methods of traffic organization. Firstly, the paper carries out a comparative analysis on the relevant theories of traffic incident, make sure the research object of the paper, which directly or indirectly harmful to urban traffic. And the incident urban road traffic system disorders or control caused by all kinds of unexpected events from the road is the key of the research. On this basis, the traffic flow characteristics of traffic incidents and road network reliability are studied. Take the traffic capacity, vehicle delay, secondary accidents and the service level four aspects to research the affect of urban trunk road traffic incident. At the same time, considering the rescue on the implementation of traffic impact, draw event method to determine traffic impact scope and establish emergency evacuation model lay the foundation for later. Then, on the basis of the study of conventional traffic organization method, sum up the suitable for urban trunk road traffic incident emergency organization method and intelligent transportation system. And through the improvement of general traffic channel model, the paper establish both relief and emergency evacuation model of channel which ensure emergency traffic organization of scientific and efficient. Next, the paper select scope, the location, the time as evaluation index and the fuzzy comprehensive evaluation method to determine the level of emergency events. According to the emergency level, the paper set up the corresponding organizational plan to provide scientific and effective method of the rapid disposal of traffic incidents for emergency management department of transportation. At last, the paper assumes that at Chongqing Jiangbei Jiazhou road somewhere, a bus spontaneous combustion. According to the study of events, the paper implement emergency traffic organization, and verify the organization effect and feasibility of the scheme with the simulation software.The paper firstly take urban trunk road traffic incident as research object and establish both relief and emergency evacuation model of channel.Then, the paper put forward the emergency level determinating methods. At last, the paper formulate corresponding grade organization plan to improve the traffic administrative department of the emergency organization management and decision-making level when urban trunk road traffic accidents happen.
