Construction Of Urban Traffic Network Jams And Congestion Evalution System

Increasingly prominent contradiction between supply and demand of urban traffic, the resulting from the urban traffic congestion become ill. Traffic jams to urban environment pollution, raise the cost of social efficiency, etc, severely restricts the development of the city. While the city transport system is very large and complex, and the reason is caused by traffic jams variety. In the empirical research, on the basis of sample data, based on the large-scale urban traffic network congestion evaluation index system for the future better solutions for the urban traffic congestion problems and promote the sustainable development of urban has important theoretical and practical significance.This will influence factors of traffic congestion and analytic hierarchy model AHM to study the causes of urban traffic congestion. In a systematic evaluation and management theory and based on the urban traffic, basic concepts, such as traffic congestion and its attributes. Through the analysis of urban traffic elements and text analysis, the urban traffic congestion causes questionnaire and please to the relevant experts were preliminary examination. In Qingdao city residents are trying to seven groups on a large scale, the empirical research on SPSS13.0 software survey results based on exploratory factor analysis, reliability and validity standard won the urban traffic congestion and the main factors affecting the dimensions, constructs the observation model of factors affecting urban traffic congestion. Using analytic hierarchy model of a AHM weight factors set, According to the research results and the basic situation of urban transportation, urban traffic congestion problem of the key measures.
