Safety effects of maintenance treatments to improve pavement condition on two-lane rural roads – Insights for pavement management

The research used data from two-lane rural roads in Ontario, Canada to evaluate the change in safety following maintenance treatments to improve pavement condition as measured by International Roughness Index (IRI). The state-of-the-art empirical Bayes (EB) before-after methodology was applied to estimate the effects on crashes, separately for arterial and collector roads. The results indicate statistically significant reductions (PThe accepted manuscript in pdf format is listed with the files at the bottom of this page.
