What happened
National Highways Limited awarded this contract to Arcadis Consulting UK Limited worth £139,991 on 12 Oct 2026. The contract runs until 31 Mar 2027.
Description
Consultation undertaken as part of the Road to Zero Harm (RTZH) research
project identified gaps in our knowledge related to the effectiveness of a
specific set of longitudinal road marking types on safety outcomes (defined
below). This work seeks to improve our understanding of how these
longitudinal treatments influence driver behaviour, collision likelihood and
severity outcomes. It will result in improved estimates of the KSI reductions
that could be expected from these treatments on the Strategic Road Network
(SRN). The outcome of this work will also provide recommendations (1) on
the road types, site characteristics, and operating conditions where
these markings are expected to deliver the greatest impact on KPI1
(Reduction in KSIs on the SRN); and (2) how remaining barriers to
greater use of these markings could be overcome.
