The real-time dispatch methods for urban rail transportation

This paper analyzes the real-time dispatch for urban rail transportation and puts forward a customized gathering and processing method for the passenger flow data. Obtain the unidirectional real-time non-uniform departure time-table, which will act as the basis of the train dispatch, by building a model with the departure interval as the model´s variable, the maximum departure interval as the aim, considering the minimum departure interval, the maximum accepted waiting time and the limit of carriage capacity. After testing by examples, the real-time dispatch model is absolutely effective. In addition, this model can be solved simply, and is convenient for the computer programming. It makes the real-time dynamic dispatch for urban rail transportation possible combining with the existing techniques and equipment.
