To achieve a goal of reducing highway crash fatalities by 4% each year to improve roadway safety, the Georgia Department of Transportation (GDOT) is actively seeking opportunities to incorporate safety improvements into its current pavement preservation program. The pavement preservation program, especially resurfacing activities, can effectively address safety concerns, such as hydroplaning and skidding, caused by pavement deficiencies, such as deep rutting, low skid resistance surface, inadequate superelevation, etc. With severe funding shortages in recent years, GDOT has experienced an increasing number of deferred resurfacing projects, which exacerbates pavement deficiencies, raises safety concerns, and, consequently puts the general public and GDOT at risk. Integrating safety improvements into the existing resurfacing program provides GDOT an opportunity to not only address the aforementioned issues, but also optimize limited resources and minimize traffic interruptions to the general public. Therefore, a means for incorporating safety improvements into GDOT’s existing resurfacing program is much needed and has been studied in this research.
