| The Urban-rural area traffic accident prevention research in snow and ice conditions Urban-rural area means it located in urban and rural transition belt . The Geographical, social, economic and cultural conditions of this area are rather special. The level of road are disordered , and the transports don`t run on their way . Especially on low-level roads of urban-rural connecting sections , motor vehicles and non-serious motor vehicle Mixed . Because different speeds,the traffic flow become unstable and overtaking phenomenon is very serious . In snow and ice conditions , when cars through this area, the problem will be more and more complex and rear-end collision is easy to happen .In this paper , we analyzed the influence of humen,cars,roads and environments by statisticed the traffic accident data . Combine features of various factors under normal weather, we established traffic accidents and the relational of various factors model. On the basis of comprehensive analysis of various factors in snow and ice conditions which led to traffic accidents in the urban fringe roads , we build urban-rural road safety Evaluation System and use entropy theory to determine the index weight, and establish urban-rural road traffic accident prediction model .According to the properties of a single indicator measure the weight of worth and value to the multi-index comprehensive measure of value, confidence criteria for identifying the use of snow and ice conditions, urban-rural status of the level of road safety, the study analyzed the possibility of traffic accidents.By case analysis shows that: Urban-rural conjunction region, the municipal management is difficult . Therefore , authorities at different levels of governance must join together to solve the traffic problem. For the urban-rural roads of the specific characteristics and lead to urban-rural factor in frequent road accidents, the need to increase management efforts to reduce urban-rural accident rate. |
