Abstract Research purposes: The railway line selection has a wide range of areas, multiple influencing factors, and strong multidisciplinary comprehensiveness. The research and development of intelligent line selection is difficult, and the efficiency and effectiveness of its application have not yet reached widespread promotion. The intelligent railway line selection system is developed, key and difficult points are identified to break through them step by step, new perspectives are proposed on path planning, local optimization, human-machine interaction, etc., in order to supplement and improve existing theoretical methods, and improve the efficiency and quality of line selection design.
Research conclusions: (1) Conducting system research and development through three steps: channel search, scheme optimization, and human-machine collaboration, and fully reusing automatic vertical section design as the basic function, can significantly reduce research and development difficulty and improve research and development efficiency. (2) A method for automatically exploring terrain in large scenes is proposed to obtain high cost areas for bridges and tunnels, and to construct a triangulation cost graph based on the boundary feature lines of the areas, which can improve search adaptability and accuracy. (3) Based on Dijkstra's shortest path search algorithm, automatic path planning can greatly improve search efficiency and effectiveness. (4) Adaptive optimization of horizontal and vertical lines, real-time linkage of horizontal and vertical lines, and system fusion based GIS line selection can flexibly meet practical needs and enhance system applicability. (5) The research results can provide reference for the development of intelligent line selection systems for railways and highways.

Key words： intelligent railway line selection cost graph channel search differential evolution horizontal and vertical linkage GIS line selection
