As disadvantaged group in the passenger flow of rail transit, the elderly has different characteristics and needs when carrying goods, and face behavioral obstacles objectively existing in the space. Starting from the relationship between behavior and space, this paper research and analyze the behavior differentiation characteristics and behavior occupation of the elderly under different carrying conditions, and focus on the detailed spatial contradictions. On this basis, from the feasible cutting-edge technology application in space, device, guide system, public furniture and other aspects, this paper discusses the space adaptation measures of transfer station hall space to meet the needs of special group behavior, and carries out micro simulation through human factors engineering software JACK to verify the effectiveness of the measures. The research results can provide reference for micro space simulation and detailed design of public space of traffic buildings.
