In urban road network, efforts should be made to avoid congestions on some key roads and intersections not only because more vehicles are involved but also because they block more connections of important zones. The concept of Betweenness in complex network theory is used in this paper to measure the role of certain intersection and road section in keeping the connectivity of key zones. Analysis on Shanghai urban road network shows that congestion on a little proportion of road sections and intersections may cause large-scale connection problems. And such key road sections and intersections in Shanghai road network are found and illustrated with the help of GIS software. At the end of this paper the result is proved to be stable and representative.
