1 S U M M A R Y Factors Contributing to Median Encroachments and Cross-Median Crashes Research was conducted to investigate the factors that contribute to median-related crashes and to identify design treatments and countermeasures that can be applied to improve median safety on divided highways. The research used a combination of interdisciplinary field studies of locations with high frequencies of median-related crashes and systemwide crash data analysis including sites with the full range of median-related crash frequencies.

2confirmation could be developed for some factors, the interdisciplinary field studies, by themselves, provide evidence that all of the factors listed above contribute to median-related crashes. The findings summarized above indicate that improvements to the contributing factors listed have the potential to reduce the frequency of median-related crashes and can supplement traditional median safety programs that focus on reducing the consequences of leaving the roadway and encroaching on the median.

3 • Provide static signs warning of weather conditions (e.g., bridge freezes before road surface) ; • Apply sand or other materials to improve road surface friction during winter storms; • Apply chemical de-icing or anti-icing as a location-specific treatment; • Install snow fences; and • Raise the state of preparedness for winter maintenance.
