The focus of this paper is on facilities planning and layout design of a railway station based on pedestrian movement and volume. It is important to ensure efficient passenger flow at stations from entering/leaving the station to departing/arriving at the station. One way of improving the passenger flow is by examining the current facility layout and exploring alternative designs thereof. A good layout of the service facilities in a station can reduce the total walking distance of passengers to and from various facilities. It improves the overall service efficiency and quality of the station.
The assessment of station design by applying a pedestrian flow simulation model, is addressed. In particular, station design issues pertaining to the way the layout and infrastructure items will influence pedestrian flow operations with level of service (LOS) and congestion, were investigated.
Principles and guidelines for railway station design were then explored. From this an acceptance criteria (Fruin's Levels of Service) were identified with which the appropriateness of different station design components (stairs, walkways, platforms, queuing areas) were evaluated.
A case study of a typical railway station was investigated to explore its current situation. These findings were used as inputs for the simulation model. The assessment of the station's design was analysed by applying dynamic simulation to model the current situation (Base Year Model) and the future situation (Future Scenario Model).
The Base Year Model was developed to demonstrate the current peak hour operations and pedestrian flows.Critical areas at the station were identified as the stairs at the entrances, the faregate lines and the stairs leading to the busy platform. The data of these critical areas were obtained through SIMIO simulation and evaluated against the recommended Levels of Service. The model proved the existing layout adequate to handle the current demand.
A Future Scenario Model was developed to test if the critical areas could handle the projected demand. The model showed the existing layout adequate to handle the projected demand except for the south faregate line where large queues were formed by pedestrians trying to exit. In was recommended to add an extra two faregates which resulted in shorter waiting time per passenger.
