| Abstract: | The meaning of network vulnerability was clearly defined. Considering the characteristics of road networks, a complex network method was improved. A composite model was provided for identi- fying the vulnerability of road network based on a community partition algorithm named GN algo- rithm. The importance of links was judged by their betweenness. In the basic of road network struc- ture and traffic demand distribution, the space distribution of vulnerable links and the failure orders of them were identified. At last, a real road network was set as an example to analysis the result and practical utility of this model. This provided decision support for traffic planning and management. |
