PLG02 The Application Of Conflict Areas On The Highway (2026)

The purpose of this document is to define a conflict area as referenced in BS5489-1 Road Lighting, CIE Standards and EN13201 and to provide the lighting designers with guidance on lighting such areas and the application of conflict areas.

Since the issue of the British Standard for Highway Lighting BS5489: 2003, the application of Conflict Areas has caused a significant degree of confusion. The definition as published in BS 5489: 2003 say “Conflict areas are typically junctions, intersections, roundabouts and pedestrian crossings, where significant streams of motorised traffic intersect with each other, or, with other road users such as pedestrians and cyclists.”

This Professional Lighting Guide PLG02 not only gives a clearer picture of various types of conflict area but also assists the designer in determining if a junction is a conflict area and explains the functions of lighting conflict areas, along with the extent of the conflict area, something which in the past has given constant concern to the lighting designer.

This Professional Lighting Guide is now referenced in the new British Standard and is a ‘must-have’ for any lighting designer who is required to design any type of road lighting scheme.
