Research on operation adjustment of multiple speed trains which was based on GA-Based Model of segment structure

Based on the transportation mode of high-speed trains and mid-speed trains operating on the same line, considering the delay time of different level trains influence the total late time differently and setting the double control parameters, the mathematical model of the train traffic control is built. According to the theory of genetic algorithm, the sectionalized structural optimization for chromosome coding is designed; model of solution algorithms is established. Using the adjusting algorithm based on genetic algorithm, a simulation system which was fit for the train traffic control of passenger dedicated railway is designed and by simulating the operation adjustment matter in an area of WuHan-GuangZhou passenger dedicated railway where it was from WuChang to YueYang, the feasibility of this method has been verified successfully.
