About the research
Research objective: Using Iowa DOT data under nighttime conditions, this research effort is focused on achieving the following objectives:
1. Capitalize on current research efforts and develop a systematic method to compare pavement marking and crash data for a given roadway segment.
2. Investigate the impact that varying levels of pavement marking retroreflectivity have on crash performance.
3. Use these findings to develop strategies for agencies to use indetermining the level of investment needed in pavement markings.
