The Influence of Subway Construction over Service Level for Urban Roads

At present our country＇s urbanized level enhances largely, many cities all begin the subway construction.According to the skin texture analysis about the urban subway engineering construction effect on the urban road transportation, the article obtain the concrete method which apply degree of saturation, the delay to evaluate the service level of the road section and the intersection, and propose the measure of dredging up road traffic flow during the subway construction.Finally this article take the transportation influence example of Xi＇an subway two line engineering construction period, obtain the anticipated analysis effect.
