Abstract

In 2010, the American Association of State Highway Transportation Officials (AASHTO) published the Highway Safety Manual 1st Edition (HSM). At that time, the AASHTO Committee on Safety established a goal in its Strategic Plan to institutionalize the HSM and its associated analytical tools to help transportation agencies make data-driven decisions, advance the science of safety, and to ultimately reduce fatalities and serious injuries. One proposed action in support of that goal was to establish and maintain an HSM Implementation Pooled Fund Study. The Federal Highway Administration agreed to organize and manage the TPF-5(255) Highway Safety Manual Implementation Pooled-Fund Study, in which 22 States ultimately participated. With the anticipated publication of the AASHTO HSM Second Edition (estimated 2025), there is strong interest from States to establish a new pooled fund to accelerate implementation of HSM2. This study will conduct research and develop products to enable States to accelerate their implementation of HSM2. A Technical Working Group consisting of one representative from each participating agency will help identify and prioritize the specific tasks and products.
