摘要：AbstractIn order to plan rail transit network in metropolitan area, this paper firstly analyzes metropolitan space structure and features of land layout. It then proposes an effective rail transit network system in Chinese metropolitan area and provides technical suggestions based on the available experience with rail transit network systems and corresponding connection models in foreign metropolitan areas. This study considers the land layout, passenger flow distribution and the corridor characteristics. It also employs Yangzhou as an example. The article suggests that the suburban transit with ribbon land layout in the metropolitan area is not suitable to directly enter the city centre and station is needed in the periphery of the city centre to connect urban rail transit network system.
