Research On Optimization Of Passenger Train Operation Scheme Of Zhengzhou East Railway Station

In recent years,the mileage of China's high-speed railway has been continuously increasing.With the gradual establishment of the high-speed railway network,more and more passengers choose to take high-speed railway trains when traveling.High-speed railway passenger trains not only bring comfortable and safe experience to passengers,but also bring more convenience to passengers.Due to the unbalanced characteristics of passenger flow distribution,under the current passenger train operation scheme,the incongruity between the station transportation capacity and passenger flow demand,or the difficulty in obtaining one ticket or the high vacancy rate of trains have occurred from time to time,which has increased the operation cost of the railway and caused the unreasonable utilization of transportation resources.High-speed railway hub stations are the key points for passenger trains to meet and evacuate on many main lines.Due to the many connecting directions,the capacity utilization of high-speed railway hub stations and the rationality of passenger train operation plan will have an important impact on the transportation capacity of regions and road networks.In this paper,through the comprehensive analysis of the objective factors such as the location of the high-speed railway network where Zhengzhou East Railway Station is located,the technical and equipment conditions of the station,and the equipment and facilities configuration of the station,the restrictive conditions of the station's passing capacity are obtained.Through the analysis of the development law of passenger flow in Zhengzhou East Railway Station and the comparative analysis of the characteristics of passenger train handling in the station,the problems existing in the station's use of tracks are obtained.Focusing on the increasing trend of the peak passenger flow of Zhengzhou East Station,combining with the historical statistical data of the peak passenger flow of Zhengzhou East Station,the grey prediction model is adopted to predict the peak passenger flow of Zhengzhou East Station,and the passenger flow prediction data is converted into the starting passenger train operation plan of Zhengzhou East Station.Based on the application of station tracks,the predicted train operation plan is compared with the current train operation plan of the station,so as to guide the adjustment of the station train operation map during the peak passenger flow period in 2019.
