Research On Operation Organization Of Urban Rail Transit Ultra-long Line

With the expansion of urban size and the explosion of urban population,ordinary bus system cannot meet daily passenger travel demand anymore.Meanwhile,the increased number of motor vehicles on the city led to urban congestion,so,urban rail transit which is characterized by its speed,safety,punctuality,comfort,large capacity,low energy consumption,light pollution become more and more prevailing in major urban cities.In recent years,China's rail transit is developing by leaps and bounds,especially in quantity and scale,and the length of a single line construction is also increasing to meet the requirements of urban development and passenger travel demand.Nowadays,many cities have a single length of track construction breakthrough 40 km,which is defined as the urban rail transit ultra-long line.Starting from the difference between urban rail transit ultra-long line and conventional rail transport,this article analyzes the passenger flow organization of urban rail transit ultra-long line.Through the analysis of the rail transit routing model,routing choice model is established.Through the analysis of the stop mode,the express train station model is set up.First,when the length of rail transit is more than 40 km can be called urban rail transit ultra-long line according to the analysis of China's rail transit planning mileage and "urban rail transit project construction standards".In addition,the urban type of long line of urban rail transit served for has been analyzed.Contrast ultra-long line and conventional line in the characteristics of passenger flow and train operation organization,train routing mode and stop mode will be selected as the main object to be study in this paper.Then,based on analyzing the forming mechanism of the rail transit passenger flow and the factors influencing the passenger flow,traffic characteristics of temporal and spatial distribution of ultra-long lines is specifically analyzed.And the principles of organization of large passenger transfer station,features,streamline and methods is also studied by taking into account of the characteristics of large passenger transfer station.Focusing on analysis of the transferring passenger flow,its organization mode is studied,and the main evaluation methods both at home and abroad are also introduced.Next,by analyzing the train routing mode,the passenger flow feature which all train routing modes adapt to is raised.Through analyzing the routing model selection principle and the influence factors,the routing mode of ultra-long line is researched.The train routing comparison model is established based on fuzzy soft sets by using its information fusion arithmetic.In this article,a case study is used to prove the feasibility.Finally,by analyzing rail transit stop mode,and the feature of the operating and the passenger flow,express/slow train stop mode is suitable for long urban rail transit line will be proposed.Therefore,the express train station model can be established based on the objective that line passengers can save time most.
