Abstract:

Aiming at the characteristics of the complex structure of railway junction and the difficult drawing process of train flow diagram, this paper study on the automatic generation of train flow diagram for railway junction. There are more connections to railway junction station. Train flow lines are difficult to settle in the station area. State matrix is introduced and state variables are used to record the distribution of the train flow lines in the station area. Train type is the primary sort and train flow is generated in the order of path length from long to short. Annotation of train flow is achieved with indicated lines. Software system is developed to implement the algorithms. Train flow diagram is automatic generated with annotation based on the junction net, train flow matrix, the station layout and their links. The example shows the effectiveness and feasibility of the algorithms and software.
