时段变化下多模式城市公共交通网络脆弱性分析
Vulnerability Analysis of Multi-modal Urban Public Transportation Networks under Time-Varying Conditions
摘要
Abstract
Urban public transportation networks are highly susceptible to service interruption caused by unexpected events,making resilience enhancement a practical need.Scientific assessment of network vulnerability under various disturbance forms the foundation for resilience enhancement.With the growing integration of multiple transport modes,the overall network structure and service capacity exhibit more pronounced temporal dynamics.Its vulnerability is difficult to fully characterize in existing studies.To this end,a multilayer network model was constructed.Nodes from multiple dimensions were evaluated and ranked.Corresponding multidimensional attack scenarios were then designed.Based on the performance evaluation model centered on both travel efficiency and service supply,the vulnerability across various time periods and scenarios was quantified.Using Chengdu as a case study,the results demonstrate significant temporal differences in vulnerability.The system is particularly subject to the failure of critical nodes during the daytime,especially peak hours.When the failure rate reaches 20%,the performance declines sharply,with the highest effect of integrated dimension attacks on the network functionality.These findings highlight the necessity of time-differentiated protection strategies and provide theoretical support for the performance assessment and resilience enhancement of urban public transportation systems.关键词
