Research Into The Contermeasures And Measures To Alleviating The Traffic Congestion Of Nanchang City

Urban traffic congestion of Nanchang City has been worsening under current road condition as the surprising increase of total vehicle and traffic demand due to fast society and economic development. And definitely, this ubiquitous city problem restricts society and economic of Nanchang City from developing faster and more steadily. It has been a problem of instancy to be solved that alleviating the traffic congestion and improving the transportation efficiency.This thesis analyzed the main traffic problems of Nanchang City based on macroscopic aspect. First, we calculated out a desirable road volume and its structure that matches Nanchang's development. Then, aimed at sustainable development, we build an optimization model of general transportation efficiency by whose results to analyze the problems existed in transportation structure of Nanchang and raise some optimum method. According to the above, we studied and exposed some feasible measures to alleviate the traffic congestion of Nanchang City.
