基于动态用户均衡的多模式公共交通鲁棒性评价
Robustness Assessment of Multimodal Public Transport Systems Based on Dynamic User Equilibrium
摘要
Abstract
To address the limitation that traditional user equilibrium is insensitive to upper capacity limits,a saturation threshold and a penalty coefficient are introduced,resulting in an improved dynamic user equilibrium model.A bi-level metro-bus public transit network framework is established,with network performance quantified using metrics such as generalized travel cost,station-based employment and residence density,and traffic flow distribution.Parameter sensitivity analyses are conducted on demand levels,the saturation threshold,and the penalty coefficient,followed by evaluation of transit network responses under various failure scenarios.Simulation results demonstrate that the proposed method can effectively evaluate network robustness and identify critical nodes and links in a multi-modal public transit network under various conditions.关键词
