Yale-Kilgore Road Safety and Traffic Assessment

This case study presents a safety analysis by the Federal Highway Administration, Western Federal Lands Highway Division (WFLHD) Highway Safety Team. The WFLHD used the Interactive Highway Safety Design Model (IHSDM) software as part of the design process for the rehabilitation of Yale- Kilgore Road. The Yale-Kilgore Road corridor is a county owned and operated two-lane undivided road located in Clark and Fremont counties in Idaho. The project corridor is an important recreational and commercial artery for the community. As a rural highway in and around a national forest, it has many unique challenges that may not exist in more urban and suburban environments. The Yale- Kilgore Road Safety and Traffic Assessment is a practical example of how the suite of IHSDM modules can support typical project development in an atypical context. Although the corridor is currently a mix of paved and unpaved surfaces, with speed and out-of-town traffic representing major concerns in both the present and the future, IHSDM assisted practitioners with the analysis tradeoffs necessary to make informed design and safety countermeasure decisions. The ability to analyze the corridor from a broad perspective (i.e., not crash prediction alone) allowed WFLHD to assess targeted improvements along the corridor, especially along segments of the corridor where the relative crash risk is highest.
