Research on Statistical Index and Evaluation System of Urban Rail Transit Train Delay Based on Operation Diagram

Abstract

There are many problems in the operation of urban rail transit. Delays in train operation (late) are one of the most common and closely related issues. The transportation object of urban rail transit train has great randomness and fluidity, which makes the operation difficulty of urban rail transit increase. The train is very susceptible to many interference factors during the running process, resulting in disorder of train operation order.Based on the classification of train delay events, this paper analyzes the causes of delays and the mechanism of delay propagation, and extracts the key parameters and parameters from the key links. Based on the existing traffic statistics indicators, a set of statistical indicators for train delay events is established. And gives the calculation method of the indicator. According to these statistical indicators, the evaluation index system of urban rail transit train delay level is constructed. The establishment of the evaluation index system has reference significance for objectively evaluating the severity of train delay events and the level of train delays, and formulating a scientific emergency response method for train delay events.
