Subways and underpasses can evoke a “fear of crime.” Though not always present in all station settings, passengers may feel uncertain in enclosed spaces, a concern lighting can address.
It is particularly important that subways are well lit and feel appropriately bright, with a managed transition of illuminance from adjacent areas. Where restricted lines of sight exist, the lighting should be designed to help eliminate any dark spaces.
Transport subway lighting may well be on 24 hour operation and could also be subject to unwelcome attention in the form of vandalism. Good lighting inspires user confidence and helps discourage criminal behaviour. It is therefore particularly important that lighting is especially robust and requires little in the way of maintenance.
Technical Support
BS EN 12464‑1:2021 recommends a maintained illuminance of 100 lux for subways between platforms designed to accommodate large passenger flows. However, the Accessible Design Code of Practice (Version 04, March 2015) recommends a higher level of 150 lux, together with clear directional information, to support accessibility and wayfinding.
Given the differing guidance, it is recommended that subway lighting is designed in accordance with BS 5489‑1:2020, Code of Practice for the Design of Road Lighting.
Whilst not specific to railways, BS 5489‑1:2020 provides lighting requirements for pedestrian subways and underpasses and specifies higher daytime illuminance levels of up to 350 lux, with lighting controls to permit a reduced level of 150 lux at night. This approach takes account of adaptation and transition between day and night conditions while providing lighting levels that support passenger safety, security, and comfort.
