Inspection and assessment of road markings and road studs

(formerly TD 26/17)

Version 0.1.0

Extracts from the Introduction to this standard.

“This document provides general information to support the inspection and assessment of the road marking and road stud asset. It specifically clarifies the risk based approach when considering renewal of these assets.”

“Background:

This document sets requirements for inspection regimes to be carried out for road markings and retroreflecting road studs, (including light emitting (active) road studs), on motorways and all-purpose
trunk roads as agreed by the relevant Overseeing Organisation. These are necessary because:

1. if there is a failure in the performance of road markings and retro-reflecting road studs, this affects their legal status or that of an associated statutory provision;
2. proliferation of road markings can have a detrimental effect on the visual environment and comprehension by the road user;
3. the visual performance of road markings degrades over time, reducing conspicuity and legibility;
4. road safety can be affected by the reduction in the visibility and legibility of road markings;”
