Description
The Colorado-specific safety knowledge base, developed and effectively applied in the design process at CDOT, is not yet used to inform the planning process. This report transfers the use of these Colorado-specific, predictive and diagnostic tools to the transportation planning process. It develops a proposed methodology for the Explicit Consideration of Safety in the Transportation Planning Process by focusing on science-based and data-driven project...

Description
Since 2000 CDOT has made effective use of Safety Performance Functions (SPF), Level of Service of Safety (LOSS) concept and diagnostic norms to prioritize, plan and scope safety improvements on all projects. A recent trend in road safety research, however, is to develop SPFs for each crash type. This approach is significantly more costly and labor intensive than the one used by CDOT, the benefits of this approach, however, were not well understood....

Description
Deployment of 2+1 Road with Barrier in Colorado certainly has potential to improve safety where it replaces conventional 2-lane highways, primarily by preventing head on and sideswipe crashes. The Swedish design is most widely implemented and has a record of success, so Colorado drivers expect the "slow" lane to be the ending lane, and somewhat gentler tapers than Sweden employs.
