Reliability of Accessibility: An Interpreted Approach to Understanding Time-Varying Transit Accessibility

Variable traffic conditions cause travel time uncertainty and further lead to time-varying accessibility. Most current studies do not fully consider fluctuations in accessibility use complicated methods that likely overestimate the level of hinder application measures. To address this issue, we utilized large-scale open-source data proposed an interpretation reliability concept incorporates reliability, uncertainty, a cumulative opportunity measure. We examined Shenzhen, major city China, focusing on transit job opportunities. The results demonstrate displays bimodal distribution along urban railway lines can be used calculate impact railways terms punctuality. new approach illustrates characteristics form probabilities provides guidance for governments.
