COVERED PLATFORM

Lighting levels and uniformity must meet specific standards to ensure all relevant objects and surfaces are easily and immediately visible, whether the platform is empty or crowded. Areas of concern include signage and identifying the edge of the platform as appropriate levels of horizontal and vertical illuminance must be balanced with the need to minimise glare. Ensuring a clear field of vision for the driver is vital to allow effective processing of a visual signal prior to entering and exiting a platform.

Whilst it may be tempting to space luminaires as widely as possible for reasons of economy, station platforms can experience sudden flurries of intense activity. It is important that lighting takes fully occupied circumstances into account.

Lower output luminaires, more closely spaced, will help put sufficient light in the volume of the space . This helps when a platform is crowded. Good illuminance on the vertical structure of the canopy can also go a long way to raising the perceived brightness of the whole platform setting.

All luminaires should incorporate higher levels of impact resistance than standard fi ttings, especially where they are accessible to members of the public.
