Abstract
The railway network planning system occupies a crucial position in the field of transportation infrastructure planning in China.In system construction,its diverse classification methods meet the planning needs of different levels and objects.From the medium-and long-term and five-year plans based on the time dimension to various railway plans focusing on specific research objects,they have all laid a vital foundation for the orderly progress of railway planning and construction.This paper studied the composition of the railway network planning system and analyzed the main content,planning methods,and planning functions of the railway network planning.According to the development of the railway network planning,it reviewed the development process and role of medium-and long-term railway network planning in railway development.On the premise of summarizing the development of the railway network planning,it discussed the development trend of the railway network planning under the new situation,put forward the planning concept of building an integrated multi-level rail network,and explained the concept by taking"four-network integration"in Yangtze River Delta for example,which provided references for railway planning research.关键词
