Transportation Condition Of Urban Road's Traffic Safety Analyze And Research

With the development of national economy and the improvement of living standard, the traffic plays more important role in everyday living, and the urban road traffic is especially important in it. The urban road traffic helps the people to move quickly and efficiently, while it could endanger life and possession similar the other traffic style. So it is an important task in modern time how to protect the people life and possession in urban road traffic. Traffic engineers are dedicated to theoretical, technical and applicable researches, hoping to reduce the harm of traffic accident and protect people's lift and property.Based on the results of traffic safty researches domestic and international and the condition and characteristics of domestic urban road traffic, this thesis brings two methods to equivalent the urban traffic safty research: urban road safety principal component analysis and the targets of equivalent accidents analytic hierarchy process. Based on viewpoint of everything serves for human being, urban road safety principal component analysis carrys on prepare evaluation of the facilities and environment of the urban road traffic and analyzes the incline that aggrandizes the duty of drivers and ignores the effect of road factors that could prevent or induce the urban road traffic accident, then implement the evaluation of urban road safety. This method is propitious to discover dangerous section of the road, and advice the relevant department to build and repair it in time. Urban road safety the targets of equivalent accidents analytic hierarchy process is great emphasized on the safety evaluation of the operational or reconstructed road, which utilizes the traffic accident targets to carry on further urban road safety adjudicate. Urban road safety principal component analysis and the targets of equivalent accidents analytic hierarchy process are complements with each other.On the basis of the accident data of Huaian city and the support of system safty theory, through analyzing systematically the urban road traffic condition, the author develops the urban road safety evaluation methods and safety concealed identification methods which are suitable for domestic urban road. Accordingly, it provides partially safety management with scientific elements insures that can make full use of the function of road traffic system.
