Urban Road Traffic Safety And The Analysis Of Influencing Facters

With the acceleration of the urbanization process, people has a higher demand for urban traffic.Safety function as the most basic functions of city road traffic system is becoming more and more important. So how to maximize the urban road traffic and avoid harming the people's lives and property will be a difficult task at this stage. So it is necessary to systematically study the actual urban road traffic safety situation and the afterwards correction changes into beforehand prevention.The safety of urban road traffic safety will have been greatly improved.The Urban Traffic Safety System is regarded as the research object of the thesis. Using data mining association rules algorithm,structural equation model in multivariate statistical methods,Set Pair Analysis and other theories and methods analysis the reason of the urban road traffic accident,influcing factors and the correlation between them.We applied the Set Pair Analysis to the the evaluation of Lanzhou city road traffic safety.Firstly, the thesis definite the urban traffic accidents factors concept trees and establish data model using star configuration. In the data model, each dimension are seen as a predicate, We use weka software to analyze the Lanzhou City Red ancient area's traffic accident data about the mining association rules. The results showed that road traffic accidents mainly caused by the speeding and not keeping a safe distance.The thesis is based on the existing research on Urban Traffic Safety factors. We designed the Urban Traffic Safety Advisory questionnaire and construct the structural equation model on Urban Traffic Safety Factors.Using spss software conduct a reliability analysis on the data obtained in questionnaire. We use Amos software proceed model fit tests to determine the path coefficients of the urban road traffic safety influence factors and effect degree. The results showed that: there has a significant positive correlation between the human factors, environmental factors, management factors,vehicle factors and traffic safety, and the degree of influence from big to small, and the observed variables have a discrepancy on latent variables.The paper select the person, vehicle, road and environmental factors building the evaluation index system of urban road traffic safety. As urban road traffic safety system contains many uncertainties, so the paper is based on the set pair analysis theory and establish the Set pair analysis model of the Urban Traffic Safety Evaluation.The method served the connection degree of value as the evaluation of urban road traffic safety quality standards.the mothod determine the evaluation level according to the actual situation of urban road traffic safety and thereby complete a comprehensive evaluation of urban road traffic safety. We will show how this works using Lanzhou City Road Traffic Safety as an example.Finally reach Lanzhou actual road security risk leve is ??, security is good.
