Evaluation of Train Holding Strategy Based on Passenger Service Level and Safety in Urban Rail Transit
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 3
Abstract
[Objective] Holding train is a train operation scheme often used in urban rail transit under the condition of long initial delay. In order to evaluate the rationality of the scheme, it is necessary to build an evaluation model and evaluate the train holding scheme based on passenger service level and safety. [Method] Based on the complexity and specialty of passenger travel law, a train holding scheme in urban rail transit is formulated. The train holding evaluation model is built on the basis of maximum departure interval, total train delay time, train evenness, the number of delayed trains at the terminal, the number of detained passengers and passengers′ total travel time. Four sections of one urban rail transit line in Shanghai are selected to calculate the actual OD (origin and destination) passenger flow in morning peak hours. [Result & Conclusion] The calculation shows that scheme 6 is the optimal train holding adjustment scheme as it has the smallest comprehensive evaluation index. This scheme can effectively improve the evenness of the train operation diagram, and reduce the number of detained passengers, and lower safety risks at the station.
