Proposed Guidance for Fixed Objects in the Roadside Design Guide

The objectives of this research were to develop an evaluation methodology and guidance for use by the transportation engineering practitioner to quantify the relative risk of collisions with roadside fixed objects. The research results are intended for inclusion as a new chapter or supplement in a future edition of the Roadside Design Guide. The results should address a broad range of roadside safety issues considering but not limited to: traffic volume; speed; crash severity; urban and rural land use; horizontal curvature; roadway geometrics; fixed-object type, size, and offset; and fixed-object density. The effectiveness of various mitigation strategies in lieu of removal or relocation should also be considered or evaluated.
