Coupling Vitality Simulation of Pedestrian System in Subway-Transit Area Based on Walkability

A large number of studies have concluded that the agglomeration effect of rail station and urban street accessibility leads to enhanced public amenity. In particular, the effect is observed in above-ground and underground pedestrian networks in rail station precincts. Taking the Qian Hai area in Shenzhen as an example, a paper identified indicators of vitality in some above ground and underground pedestrian streets networks in a subway transit study subject area. The study then rated the vitality indicators and mapped it on a GIS platform. The platform facilitated spatial visualization of less-developed areas in the above ground and underground systems. This improves the ability of policy makers to make data driven decisions on prioritisation of public amenity and asset improvements.
