Study On Evaluation Methods Of Rail Transit Underground Station Scale And Facilities Layout

ABSTRACT:Urban Rail Transit Station is a huge underground construction and costs much higher, while it is also the most direct feeling of passengers to the rail services and has a very important status. Therefore, the overall size of Rail Transit Stations and the layout of pedestrian facilities should be based on scientific evaluation methods, systems and indicators. On the one hand, from the perspective of investors, the overall size of subway stations and pedestrian facilities should be controlled as much as possible to avoid redundancy and wasted investment; on the other hand, from the perspective of the rail transport service recipients, the perspective of the passengers, the internal distribution and traveling should meet the distribution and communication of the entry and exit, while the passenger flow and evacuation operations should reach a certain satisfaction and comfort at the same time.This paper obtains a lot of basic data through the investigation, and obtains the characteristics of walking passengers by analyzing the data. The level of service standards of Station described by the density and speed indicators is also established in this paper. By establishing a scientific evaluation methods and indicators, combined with the computer simulation, this paper studies the service level and design parameters of Rail Transit Station from the perspectives of investors and passengers, and recomends the appropriate service level and design parameters. Finally, this paper briefly analyzes the layout of AFC, and proposes the corresponding optimal solutions.
