Research On Safety Evalution And Safety Precaution Of Urban Traffic

With the development of economy and the improvement of living standard, the trafficplays more important role in normal life, 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 endangerlife and possession similar the other traffic style.The urban road traffic accidents directly affect and restrict the development of the urbantransport,and badly threaten the people's life and possession. To improve the road safeperformance and reduce the traffic accidents,the corresponding evaluation should be madeobjectively first to the urban road safety,that finds problems and provides urban road trafficsafety with corresponding solutions by analyzing and estimating. Then the disposal schemeshould be worked out which could improve the urban traffic environment effectively.Based on the results of domestic traffic safety researches and characteristics of domesticurban road traffic, this thesis analyzes influence factors of urban traffic safety and put forwardsthree methods to equivalent the urban traffic safety:principal component analysis,the targets ofequivalent accidents analytic hierarchy process and gray correlation analysis.Based on theviewpoint of people foremost, principal component analysis carrys on preliminary evaluation ofthe facilities and environment, that could pre-find the more dangerous traffic accident andtimely correct actions, guarantee to achieve maximizing the benefits of the input. Urban roadsafety the targets of equivalent accidents analytic hierarchy process and gray correlationanalysis are greatly emphasized on the safety evaluation of the operational or rexonstructedroad, which utilize the traffic accident targets to carry on future urban road safety adjudicateand complement with principal component analysis.Through analyzing the urban road traffic condition of Yangzhou systematacially, test andvrify the urban road safety evaluation methods and safety concealed identification methodswhich are suitable for domestic urban road. Accordingly, providing improvement andprevention plan in order to provide scientific basis for management decision-making of urbanroad safety, thus ensure the urban road transport system functions into full play.
