Abstract
Responsible policymakers and transportation planners must ensure safe transportation during large-scale events, especially in urban rail transit systems that are not designed to handle high demand, as overcrowding can lead to dangerous situations and even fatalities. This paper presents an approach to optimize the number of passengers allowed into urban rail transit systems, considering the limitations of trains and station platforms, while also ensuring that as many people as possible can be transported. To achieve this, we developed an optimization model embedded into an iterative heuristic that incorporates the predicted demands, real time-data and the capacity limitations of the entire system. To ensure the accuracy and robustness of our model, we evaluated our approach on a data set based on a comprehensive transportation demand simulation. Our results indicate the effectiveness of our approach. By iteratively optimizing the allowance, we can achieve a good balance between the capacity utilization and the number of people transported. Our system can assist policymakers and transportation planners to control the passenger flows and thereby prevent overcrowding and accidents.
