Discussion on the Importance of Combination with Railway Route Selection and Urban Planning

Abstract

The density of cities in Northwest China is relatively low, and the scale of cities is relatively small compared with the developed areas in Southeast China. In addition, the early urban planning hadn’t systematically plan the blue line, red line and purple line in the urban area. These caused designers ignored the influence of urban planning on route selection in the design scheme. With the rapid development of China’s economy and the continuous expansion of the city scale, the status of urban planning has become more and more important. Railway engineers need to change their ideas and pay attention to the impact of urban planning on the design scheme. Taking the high-speed railway from Zhongwei to Lanzhou as an example, this paper discusses the relationship between railway route selection and urban planning in the urban built-up area combined with the problems encountered in the design and the principle of urban planning. It is concluded that railway route selection must be closely combined with urban planning. It systematically analyzes how to fully consider the influence of environmental protection, urban land, four lines of urban planning and other factors in the process of railway selection, so as to provide reference for railway route selection in large cities.
