traffic control is the center of modern railway high efficiency and security.Train Plan is the core of progress railway transportation efficiency.Inthis paper,firstly trains traffic control is studied with discrete event system theoryana analysis method.A new thought method is provided is provided for traffic control.In this paper the relation of the trains and therelation of the trains and stations mostly studies.Petri nets theory is used to train traffic control system modeling-Petri nets train travelling control simulation system.With hierarchy represent andthe abstract capability of Petri netS, a framework is built by Petri netS traintravelling simulation system.In this framework all kinds of static and dynamicdata can be reasonably organized and processed. lt can provide a powerful helpfor train traffic transportation dispatch.A new method is provided for describing trains travelling Plan with a conflictvector and a settle vector.It can distinctly indicate conflict between the trains andstation s in trains travelling plan. It indicates a method of settling a method of settling the conflict whena conflict happened.On the base of simulation the relation of trains and the relation of trains and stations, trains travelling Plan adjust is optimized with with genetic algorhm. Amethod of travelling plan can be obtained with certain optimization.
