2006 - NZ - Safety Benefits of Brighter Road Markings

A ‘before’ and ‘after’ style of analysis was undertaken to identify whether increasing the brightness of existing roadmarkings on unlit rural state highways had resulted in improved safety, measured as the incidence of mid-block injury-causing crashes.

Comparisons were made of average crash rates, crash rates in light conditions to dark conditions, and crashes on curves compared to crashes on straight in light and dark conditions. No evidence of altered rates could be identified.
