Urban Rail Transit Train Different Marshalling Mixed Operation Of Optimization Research

In highly populated urban rail transit train transportation system, the different trainmarshalling mixed operation, due to the delay often affects other vehicles running train delays.How to move the block model based on moving block and reduce the delay spread, increasingthe line capacity is one of the important subjects of urban rail transit operation management.Optimization of train operation plan analysis helps to delay occurs, the ascending line runningability of recovery. This dissertation has analyzed the interference factors of different trainand has optimized the train running to ensure the punctuality rate of the train operation ofurban rail transit system.In this dissertation, according to the urban rail transit train traction specification,respectively based on moving block and train track moving-like operation model, theinfluence of various factors on the train track interval had been discussed, and the two kindsof block mode various interference factors in contrast have been researched, the train runstrack for urban rail transit train operation and dispatching command provide certain referencedata. Specific work is embodied in the following aspects:(1) The difference between the moving block and the quasi moving block model hasbeen analyzed, on the train track the data of the running model and traction locomotive,vehicle is analyzed, on the theoretical basis of simulation calculation of orbital data and itslayout, etc.(2) In this mode the moving block based on modeling, simulation calculation was carriedout by means of OpenTrack software selection of track section of line eight of Shanghai citylight road to Jiangpu Road, analyzed the factors of different train moving block mode ofmixed operation, the moving block train tracking characteristics of the optimization andadjustment of the train operation control system.(3) This dissertation modeling based on occlusion model of quasi moving block, analysisof the quasi moving block mode, interference factors in different trains, and VC++6.0basedquasi moving block mold train tracking simulation system. Under the condition of differentapproaches for the train marshalling of train operation are analyzed, and research and to jointhe adjustment factor to optimize the train operation plan is put forward.Through the oretical analysis of urban rail transit and the simulation results show thatmass transit train departure interval mixed operation mode of moving block adjustment,moving-like block based train control regulator mode to join can effectively improve thetrain’s volatility, increase line capacity.
