Research On Train Operation Plan For Network Operation Of Urban Rail Transit Based On Interoperability

Network operation of urban rail transit is the direction of future development, and it is an inevitable trend of network operation to realize "interoperability" between different rail transit lines. This thesis studied train operation plan in network operation condition based on the background of interoperability network operation of urban rail transit. Interoperability network of urban rail transit has not been formed in China today, and the research on this issue can give some references for the lines opened in the future. It has quite a forward innovative and practical significance.Train operation plan is the core technical document of urban rail transit, which is used to command the daily operation of the train. In the interoperability network operation scenarios, the network of rail transit operates as a whole. Faced with the complex restrict relationship between different lines, it is a problem worthy of study that how to coordinate the operation of the trains to give full play to the benefits of interoperability network rail transit lines. This thesis carried out the following research work:Firstly, factors influencing train operation plan were studied:distribution of passenger flow, train operation scheme, line capacity, level of passenger service, operation cost and complexity of organization, based on the analysis of the concept and characteristics of interoperability network operation. It provides the necessary theoretical basis for the implementation of compiling train operation plan.Secondly, we put forward the process compiling interoperability network train operation plan, and researched on the implementation of compiling train operation plan. Including the following several aspects.(1) The analysis method of line capacity of network operation was studied. This thesis mainly focused on analysising the through ability of crossing station, tracking ability of main line, turn-back capacity of turn-back station, using mapping method in combination with simulation of a single vehicle mode.(2) The making method of train plan in interoperability network operation condition was studied. Under the related constraints, multi-objective optimization model of train operation plan was established for the target to minimize waiting time of passenger, operating cost of enterprise. And also, the solving method was put forward.(3) The method of establishing the network timetable was researched. From the aspect of the whole network, the optimization model of timetable was established for the target to minimize transfer time and make the balance of the train interval, in order to realize the reasonable cohesion of trains at the crossing station and transfer station. And also the solution was put forward.Thirdly, a case was designed for analysis. Using the research results, the case was analyzed and the network train operation plan was obtained. Compared with traditional single-line operation mode, the advantages of interoperability network operation were obvious, and at the same time, it also verified the effectiveness of the proposed method and model.In the end, it summarized the main content as well as the areas that improvement were needed. And also, research direction for the future work was discussed in the thesis.
