Optimization of train plan of full-length short-turn routing mode based on data analysis

摘要

According to the analysis of passenger travel behavior, the properties of the full-length & short-turn routing mode and huge amounts of AFC data processed by CLEMENTINE, a multi-objective nonlinear mixed integer programming optimization model of train plan for a single transit line is established. The objective functions are minimum passenger travel cost and enterprise operation cost. In order to validate the feasibility of the model, Matlab software can be used to figure out the solution to a case based on TOPSIS which can convert the above model into the single objective model. The validity of the model is verified by a case, and the sensitivities of upper limit of train load factor and positions of turn-back stations are also analyzed. The results indicate that compared with single routing mode, full-length & short-turn routing mode is better and the length of short-turn routing and train frequencies have a great impact.
