Abstract:
Based on the complex network theory, the network model of pedestrian network of Chongqing commercial district is constructed, and the pedestrian network fault simulation is designed according to the real disaster analysis of the road network in the business circle and the reliability index. With Jiefangbei pedestrian road network taken as an example, case analysis of reliability is conducted and comparative study on raliability of pedestrian networks of the five major commercial circles are carried out on the basis of three types of indicators:network efficiency changes under cumulative attacks, maximum connected subgraphs changes under cumulative attacks, and network efficiency changes under single attack. The calculation lead to the conclusion of reliability evaluation, which forms corresponding opinions about of the construction and management of road network.
