Crash data show that more than 18,000 traffic fatalities per year result from roadway departures, and over 7,000 of those roadway departure crashes involved collisions with roadside fixed objects.

The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 336: Proposed Guidelines for Fixed Objects in the Roadside Design Guide helps develop an evaluation methodology and design guidance for use by engineering practitioners to quantify the relative risk of collisions with roadside fixed objects.

The document is supplemental to NCHRP Research Report 1016: Design Guidelines for Mitigating Collisions with Trees and Utility Poles.
