High-speed train rescheduling method based on dynamic passenger flow under strong wind condition

Abstract

The invention provides a high-speed train rescheduling method based on dynamic passenger flow under a strong wind condition. The high-speed train rescheduling method comprises the following steps: step 1, acquiring a high-speed train plan timetable, passenger travel demands and strong wind speed limit scene basic information; 2, a train interval operation time constraint, a train stop time constraint, a train departure time constraint, a station capacity constraint and an inter-station block interval capacity constraint are established; according to the invention, the real-time rescheduling schedule of the high-speed train and the redistribution scheme of passengers detained at each station on the railway line can be calculated within the effective time, the train dispatcher is assisted to make an optimal dispatching decision, and the train delay caused by the speed limit of the high-speed train due to strong wind and the total travel time of passengers at each station can be effectively reduced; existing railway transport capacity resources can be efficiently utilized to meet the travel requirements of passengers, the use efficiency of railway lines is improved, the negative influence of strong wind weather on high-speed train operation is effectively controlled, and the railway transport service quality and the passenger satisfaction degree are further improved.

Description

technical field [0001] The invention relates to the technical field of train operation adjustment and dispatching, in particular to a high-speed train rescheduling method based on dynamic passenger flow under strong wind conditions. Background technique [0002] China's high-speed railway is the backbone of the country's comprehensive transportation system. As of the end of December 2020, the total operating mileage of China's high-speed railway ranks first in the world. Warning, in order to ensure the safe running of trains on the rails, train speed reduction is unavoidable, and only adopting the speed reduction strategy will easily lead to secondary delays of subsequent trains, and the spread of train delays cannot be effectively controlled. Therefore, under strong wind conditions, adopting a reasonable and effective train scheduling strategy can effectively control train delays and spread range, and reduce the total travel time of passengers, which has become an urgent pr...
