Study On The Evaluation And Improvement Of Non-motor Vehicle Traffic Conflict In The Intersection Of Urban Road

Traffic accidents often happen between non-motor vehicles and vehicles.At the intersection,there is a different machine flows between non-traffic complex conflict mode,as long as vehicles and non-motor vehicles in the same plane through the intersection,it is difficult to completely avoid conflict.So the key to solve the traffic problem is to solve the non-motor vehicles conflict.The thesis studies the urban road intersection traffic conflict assessment of non-motor vehicles and Improvement.In this thesis,non-motor vehicle dimensions,motion characteristics and cycling psychological and behavior analysis to study the characteristics of non-motor vehicles traffic,statistics,urban road intersection control channel parameter distribution of non-motor ehicles transport.Based on the study on the technical definition of traffic conflict,research and analysis of the type of conflict occurs during non-motor vehicles traffic conflicts;urban road intersections non-motor vehicles traffic conflicts discrimination into conflict observation,determine the number of conflict and post-conflict number of determining the severity of three parts,the influence of non-motor vehicles and service level of conflict on traffic capacity.This thesis is suitable for urban road intersections comprehensive evaluation of the advantages and disadvantages and scope of application of the principle of AHP analysis discusses the basic steps to create a non-motor vehicle lane urban road intersections conflict assessment system,to clarify the meaning of each index and the corresponding calculation methods,and to establish the appropriate classification and rating criteria.Faced with how to solve the problem of standardization of the survey data were used in the establishment of a very large indicators and a very small indicator function,a hierarchical dimension treatment methods and indicators for assessment.Based on the urban road intersections to establish non-motor vehicles traffic conflicts evaluation system,an improved strategy for urban road intersections non-motor vehicles traffic conflicts,by summarizing the intersection comprehensive evaluation of proposals and recommendations to improve the intersection of each index,achieve non-motor vehicles urban road intersections conflict improvement purposes.In addition,it proposed to achieve the separation of the different transport systems fundamentally solve the problem of traffic conflict,feature division and development strategies of non-motor vehicles non-motor vehicle lanes.
