| The realization of urbanization is an important plan put forward by the Central Committee of the Communist Party of China.Nowadays,with the acceleration of the urban process,urban traffic problems have become more and more serious.Due to its high safety,high comfort and low pollution rate,railway transportation plays an important role in solving urban road congestion.As a result,railway transportation across the country has been actively improved.As we all know,in recent years,the city scale has been expanding outward.As a result,The passenger flow on various railway transportation lines in the city is unevenly distributed.There is obvious peak flow in the city center,while the passenger flow in the suburbs far away from the central area is relatively low.If a single operation mode is adopted without distinguishing sections,it is likely to cause problems such as short supply of trains,low comfort of passengers or waste of train resources.If we do not change the number of trains under the train and adopt the operation mode of large and small routes,it will play a significant role.On the one hand,it can shorten the departure interval of rail transit trains,improve the utilization rate and meet the passenger demand.On the other hand,it can also increase the operation capacity of large passenger flow section and improve the comfort.Therefore,we need to make reasonable planning for the train operation scheme of urban rail transit.In this article,we first analyzed the basic ideas and characteristics of train operation and routing in the urban railway transportation management organization,and then formulated guidelines that should be followed for train operation,pointing out related issues and their meaning and characteristics.I will explain.And different types of operation modes.This article briefly introduces the general situation and characteristics of Shenzhen urban railway network planning.simplifies the diagram of train operation routing of typical routing type lines(Y-type,X-type and I-type),It describes the application of different types of transportation in actual production and life,and analyzes changes in the normal parts of a train’s route in the event of a failure in different parts of the line.Through the analysis in the above chapters,an optimized model of train route planning is established.and the number of vehicles used under different types of routing is calculated check the validity and feasibility of the model.Finally,we will introduce the basic information of Shenzhen Metro Line 3,train operation parameters,and passenger flow analysis data regarding the operation route of Shenzhen Metro Line 3.Through model analysis,relevant conclusions were drawn and an optimization plan for the train route of Shenzhen Subway Line 3 was formulated.The model is validated after comparing the effectiveness of the original plan with the optimized plan type. |
