Mass transit systems are crucial in alleviating traffic congestion and fostering economic development in the surrounding areas. Transitional spaces between mass transit stations and buildings significantly improve accessibility, especially for the BTS Skytrain. Emphasizing safe travel is of paramount importance. This research aims to investigate factors related to the design and safety of transitional spaces, involving an assessment of the environment and proposing guidelines for the physical layout. The objective is to address issues such as blind corners and travel obstacles comprehensively. The study employs identified factors to evaluate transitional spaces, identify problems based on specified criteria, and incorporate feedback from area users. The findings underscore the importance of good visibility as a crucial factor for safe journeys. Walkways with a width of two meters or more in areas with dead spots and travel obstacles are safer than narrower paths. Two approaches have been suggested to tackle these issues: first, addressing physical aspects by enabling travelers to see blind corners before reaching them, determining the boundaries of dead zones and travel obstacles, and establishing clear walking routes with navigation symbols. Second, management solutions include adding security guards and equipment in dead spots, along with effective management of transitional spaces during events to handle increased traffic.
