The entrance, exit, and interchange directions must be
carefully selected for single-story side transfer stations to
optimize passenger flow. The design idea, passenger flow characteristics,
organizational difficulties, and public feedback on single-story side transfer stations such as Erligou station in Beijing are
analyzed herein. The main three-column, four-span arched structure of Erligou station is uniquely designed using
a mining excavation method for the first time in China. This multispan form
effectively addresses the spatial challenges associated with longitudinally
traversing platforms when determining the directions in side stations.
Additionally, an external security inspection area is established via mining
excavation on both sides of the station hall, positioning the least efficient
security facilities outside of passenger flow areas. These changes
fundamentally resolve the bottleneck concerning passenger throughput at transfer
stations. By employing the pedestrian simulation software to analyze traffic
patterns, operational guidance personnel are added at key nodes wherein
passengers change directions on side platforms to ensure efficient and safe
crowd management. During the operational phase, adjustments are made to
entrance and exit flow lines to meet high directness and strong purposefulness
in passenger organization needs. Based on the passenger flow characteristics
during the off-peak period, vertical elevators can be
used to improve passenger transfer efficiency. In the orientation setting, the
continuity wall and ground are pasted to the key nodes as far as possible, and
the problem of passengers′ wayfinding is solved by
emphasizing the positions of passageways and escalators. By offering guidance,
passengers can access escalators, stairs, and vertical ladders in complex
station networks, thereby enabling optimized passenger flow.
