Research On Study On The Operation Plan Of Intercity Railway Trains In Shenzhen Metropolitan Area

According to the latest Guangdong-Hong Kong-Macao Greater Bay Area railway network development plan,it is required to continue to implement and optimize the original intercity rail transit network planning in the Pearl River Delta region,further increase the construction of intercity railways,do a good job in the integration and connection of high-speed rail,general speed railway,intercity railway,urban railway and other rail transit networks,build a "Shenzhen metropolitan area on the track",improve the modern comprehensive transportation system,,the Shenzhen Metropolitan Area is the core area of the Greater Bay Area.Intercity railway has the function of promoting intercity interaction within urban circles,strengthening inter-regional exchanges that cannot be covered by high-speed railway networks,and improving the service efficiency of the general speed railway network.At the same time,the distance between intercity railway stations is generally less than 10 km,which is 20-30 km shorter than that of high-speed railway stations on average,and 2km longer than urban rail transit,and the lines mostly pass through urban centers,which has the function of rapid travel between suburban railway service metropolitan areas to peripheral groups or peripheral groups.Based on the passenger flow characteristics of Shenzhen metropolitan area,this paper analyzes the influencing factors of passenger flow,takes the passenger flow data predicted by the fourstage method as the basis,combined with the opening section of the intercity railway in the Shenzhen metropolitan area,focuses on the necessity and possibility of intercity railway interconnection in the Shenzhen metropolitan area in the study of transportation organization mode,studies the stopping mode and train interchange of the intercity railway in the metropolitan area,and designs a travel scheme that meets the travel rules of passengers in the Shenzhen metropolitan area,and models and analyzes it according to the perspective of passengers and enterprises.The operation scheme of intercity railway trains is optimized,and the train operation chart is compiled on this basis.The innovation point of this paper is that the interests of both the operating enterprise and the passenger need to be taken into account when optimizing the operation plan,and the Pareto solution set search algorithm is used to solve the problem,and a number of optimization solutions with different angles and different focuses are obtained for decision-makers to choose,and the difference in decision-makers’ preferences for passenger travel costs and enterprise operating costs will affect the determination of the optimal scheme.The entropy weight method calculates the entropy weight of an index according to the decision matrix,which can effectively avoid the influence of personal preference on the weight of each index,which belongs to the objective assignment method.The study proposes a transportation organization scheme that meets the actual needs of intercity cities in metropolitan areas,has efficient capacity allocation,and integrates multi-standard systems,which is advanced.According to the different working conditions of CTCS and CBTC signal systems and intercity railway network planning,design,completion and operation,the innovative transportation organization mode combining direct through and transit,periodicity and flexibility coordination can well adapt to the requirements of public transportation and network direct operation of intercity railway in Shenzhen metropolitan area.
