- Abstract
Urban public transportation network is a typically complex network and the local fault of network often leads to serious systemic impact, causing cascading failure. Research on cascading failure of the bus network, is advantageous to understand of the potential key individuals of the network, so as to guide the rational planning of transit network. At first, this paper proposed the path navigation strategy based on the transfer bus to describe the flow propagation law of transit network, and after which an improved failure model of the bus network based on capacity-load model was put forward. Finally, the experimental analysis was conducted based on real traffic data of Beijing, and under the improved path navigation strategy, the correlation between node load and real data reached 99.61%, accord with the real law more than the traditional path navigation strategy. Cascading failure simulation illustrated that even small-scale attacks could lead to systemic paralysis, causing serious impacts on the structure and function of network, meanwhile the damage to the functional integrity is more severe than structural integrity. Conclusion is conducted that results can guide the bus lines and citizens' travel.
