Design Characteristics of Urban Rail Transit Network in Mountainous Cities

This study introduces the topography and urban development features of Guiyang city and the planning of the rail transit network by considering the vital and challenging points of the location selection of a station of an urban rail transit line in a mountainous area and the corresponding methods. Furthermore, common challenges in line design and the station location setting of an urban rail transit line in mountainous areas, such as the shortage of construction land, narrow roads, limitations of the terrain elevation, and the single passenger corridor, are discussed in this study. The mountainous area in combination with the corresponding methods of horizontal and vertical section design of urban rail transit lines, and the methods for station location selection and station layout are given.
