The purpose of this study is to examine the change in spatial-based accessibility to the airport-rail station connecting area in Bangkok, Thailand. A recent change to the station layout is the addition of a ramp to the pedestrian bridge linking the commuter rail station to the airport from Don Mueang Station to Don Mueang International Airport. This paper utilizes available features in Rhino7 software, including the visual programming language and environment (Grasshopper) to create pedestrian path networks and Urban Network Analysis (UNA-Betweenness) to reflect the changes in the probability of congestion concerning both ingress and egress. The findings have shown a reduction in the overall probability of congestion after the installation of the ramp, which implies an improvement in passenger flow. However, detailed research on the ratio of congestion probability is essential for specific pedestrian facility improvements. It is recommended that the Betweenness method can be used to develop a crowd management plan in the railway station and effectively locate a point for signage installation.
