Slippery Slope: A View Inside a Successful Road Safety Audit
January 26, 2011
The Portland office of Kittelson & Associates, Inc. hosted an interactive workshop on January 13th that covered the following related to Road Safety Audits (RSA):
1) A brief overview of the Federal Highway Administration (FHWA) Road Safety Audit (RSA) – Guidelines and Checklist.
2) Walk through a recent RSA application - Mt. Hood Highway (US 26) on the western slope between Portland, Oregon and the Mt. Hood recreational facilities (including ski areas during winter season).
A Road Safety Audit is a formal safety performance examination of an existing or future road or intersection conducted by an independent audit team. The emphasis of a RSA is to identify opportunities to improve safety rather than critique work previously completed. The process includes pre-audit data and drawings review, a field review, an analysis of findings, and a presentation of the findings to the owner of the roadway or project being reviewed.
The Mt. Hood Highway corridor is a recent RSA example that was shared at the workshop. This corridor in the RSA is designated by Oregon Department of Transportation (ODOT) as a “Highway Safety Corridor” and is also a truck route. The RSA addressed issues common to a mountain highway, including speeds under variable weather conditions (dry pavement in the summer and snow/ice in the winter), curves, chain-on/off areas, passing locations, and other factors that contribute to high crash locations along the corridor. The RSA team included maintenance and design representatives, as well as a representative from the Oregon State Police.
This has been a valuable experience, since the process reminds the engineering industry to focus on safety rather than applying standards in a topographically constrained environment. The outcome of this project identified near-, medium-, and long-term projects. ODOT has commenced installation of the near-term projects totaling $150,000 and begun design of many the medium to long-term safety improvement to be constructed in 2013 totaling $9 million.
