Each year, roadway departure crashes in the United States result in serious injuries and fatalities. More than 1 in 3 fatalities are associated with impacting fixed objects such as trees and utility poles.
The TRB National Cooperative Highway Research Program's NCHRP Research Report 1016: Design Guidelines for Mitigating Collisions with Trees and Utility Poles presents guidelines to quantitatively determine the safety risks posed by fixed objects placed in close proximity to roadways.
Supplemental to the report is NCHRP Web-Only Document 336: Proposed Guidlines for Fixed Objects in the Roadside Design Guide, a Spreadsheet Tool, an Implementation Plan, and a PowerPoint Slide Summary.
