Train Operation Route Calculation and Trajectory Simulation and Reproduction Technology in Railway Network
This paper studies the train operation route calculation and real-time digital simulation technology in railway network,and proposes a method for train operation route calculation and trajectory simulation reproduction in railway network.On the basis of building a digital railway network map,the Yen algorithm for solving the K shortest path problem is used to generate the optimal route set according to constraints such as distance and time,and the operation route that best meets the overall requirements is intelligently calculated under combinatorial optimization.The digital simulation technology is used to build a digital simulation and reproduction model for the operation process of multi-line and multi-train in the railway network,so as to realize accurate simulation and visual simulation and reproduction of the arrival and departure,traveling,dynamic distribution and other processes of multi-line trains in the railway network.The real operation sample data of the railway network are used to test and verify relevant technologies and methods.
