Author(s): Xiao Qiang Luo, Quan Hua Hou, Ya Qiong Duan

Under the background of the current urban traffic jams growing, how to keep the city road network unblocked has a important practical significance. in this paper, through using the concept of unblocked reliability, the method, and use back-up capacity model, established a back-up capacity of road network capacity analysis theory model and its calculation method, then gives a sample calculation. The results showed that, under the restriction of road connection relations, to ensure the smooth and reliable of road network, the actual network capacity is less than its structure capacity. This work provides a new perspective for urban road network planning
