Updated Guidance Note: PLG02/26 The Application Of Conflict Areas On The Highway (2026)
We are proud to announce that the updated Professional Lighting Guide PLG02: The Application of Conflict Areas on the Highway (2026) is now available to purchase via The ILP resource page. This guidance note is to replace the previous PLG02 from 2013. The purpose of this document is to define a conflict area as referenced in BS5489-1 Road Lighting, CIE Standards and EN13201.
As there are ever-increasing distractions for drivers, keeping road users safe requires precise, actionable insights, which this Professional Lighting Guide provides.
PLG02 specifically addresses the unique challenges of lighting complex highway environments, focusing on areas where vehicles, pedestrians, and cyclists intersect.
Whether you are a seasoned professional or a developing designer, this guide has been created to provide users with practical methods and strategies to elevate their infrastructure projects.
Topics covered inside the PLG02 include:
- Detailed information on what truly constitutes a “conflict area”, helping you avoid any errors where ambient lighting levels are raised without highlighting actual danger zones.
- Expert guidance on selecting the correct C-class lighting, applying the "5-second rule" for approach roads, and effective glare limitation.
- Extensive illustrations, featuring typical column and lantern arrangements for T-junctions, roundabouts, and pedestrian crossings to maximise positive contrast and safety.
We invite you to explore PLG02 and see how it can directly benefit your organisation’s current design projects and help you seamlessly navigate road lighting classifications. We would like to thank Nick Smith for his contribution towards this 2026 edition of PLG02.
