How to light: pedestrian crossings
1. Ensuring the crossing is highly visible and distinguishable from the surrounding area.
2. Clear visibility of pedestrians approaching and using the crossing.
3. Minimising glare to drivers.
1. An asymmetric lighting solution that provides a high vertical illuminance on the pedestrian from the driver’s position.
2. Supplementary lighting that creates a clear contrast between the regular road lighting and the crossing, with clearly defined edges.
3. Adequate lighting for adjacent footways.
Luminaires should be installed 1m from the pedestrian crossing and use a low mounting height of 5-6m. As a general rule – the lower the better.
Luminaires need to be as glare free as possible to ensure maximum visibility through the crossing area, as pedestrians will often try to cross short of the crossing itself. Flat glass luminaires are therefore best.
A contrasting lamp colour from the surrounding road lighting is recommended as an effective way to highlight the carpet, for example white light on the crossing in a high pressure Sodium (SON) road installation. The same effect can be achieved in LED schemes with a simple change in colour temperature.
Finally, the light distribution from the luminaire needs to provide high levels of vertical illuminance onto the crossing pedestrians, to ensure that they are visible to approaching motorists. TR12 recommends three separate vertical calculation planes, covering the width of the crossing to ensure good visibility of the pedestrian.
The guidance for crossings located on M class roads (motorways and traffic routes) is based on one vertical grid across the entire crossing.
Rather than at three different measured points and one horizontal grid, as per TR12 – guidance for residential roads.
There are no BS or CEN standards covering crossings on these roads.
As such the levels aimed for on these grids are determined by European best practice which generally agrees that the levels should be:
Such situations are rare in the UK, but worth including as you may encounter them for European schemes.
Our Diamond+ optical system includes three light distributions specifically designed for pedestrian crossings. Many of our luminaires can be specified with our Diamond+ Z Optic, providing a variety of styles to match the aesthetics of luminaires used elsewhere on the scheme.
Our Zebra crossing optics have been designed to deliver visual comfort for both motorists and pedestrians. Offered in both symmetric or asymmetric light distributions, they can highlight pedestrians on the crossing as well as illuminating pedestrians waiting to cross. With good cut-off to emphasise the carpet and make it more prominent to approaching traffic.
