Abstract:Objective: This study explores the statistical relationship between crash occurrence probability and longitudinal pavement marking retroreflectivity.
Problem Statement: Previous research on pavement markings, from a safety perspective, tackled various issues, such as pavement marking retroreflectivity variability, relationship between pavement marking retroreflectivity and driver visibility, and pavement marking improvements and safety. A recent research interest in this area is to find a correlation between retroreflectivity and crashes, as a significant statistical relationship is undefined to date.
Background:
Longitudinal pavement markings provide guidance to road users by delineating the traveled way. These markings help protect drivers by indicating where they should be on the road to prevent collisions with other vehicles, as well as to prevent run-off-the-road crashes. Pavement markings are especially important at night.
