Committee Overview

The Committee on Truck & Bus Safety (ACS60) of the National Academies Transportation Research Board (TRB) was founded in 2003. Organizations that were precursors to the committee included a Truck & Bus Safety Subcommittee of the Committee on Transportation Safety Management and a Task Force on Truck and Bus Safety (A3B57) that championed the transition from subcommittee to full committee status. Within the TRB committee structure, ACS60 is part of the Safety Section of the System User Group.

Committee Goal

Like other TRB committees, ACS60 consists of professionals committed to advancing their disciplines and improving the North American transportation system. ACS60's goal is to:

  • Focus on motor carrier safety in all its aspects; to include research and evaluation in human, roadway, vehicle, operational, and organizational arenas as they relate to motor carrier safety.

Committee Strategic Plan

Updated in March 2020, the strategic plan (PDF, 275K) defines the focus of the TRB ACS60 Truck and Bus Safety Committee for the next several years.

Topics of Interest

Specific truck and bus safety topics of interest to ACS60 include the following: problem assessment and data, regulation, enforcement and compliance, commercial driver health and wellness (as they relate to driving safety), driver performance and behavior (human factors), carrier safety management, heavy vehicle design and technology, and roadway design & operations (as related to heavy vehicles).

ACS60 completed a TRB Circular in May 2007 entitled The Domain of Truck and Bus Safety Research. This Circular summarizes knowledge and information on the above topics and identifies major research and development needs relating to them.

Committee Functions

Major functions of ACS60 include the following:

  • Inform members of the truck and bus safety community of current research.
  • Stimulate new research and development.

Deborah Freund ACS60 Paper Award

The Deborah Freund ACS60 Paper Award is awarded each year to one of the papers accepted by the committee and TRB for publication the prior year. The winner is selected by a Paper Award subcommittee which evaluates each paper. The Award is named for a long-term, valuable member of the committee and good friend and colleague who passed away August 2014.


Members are appointed for a three-year term with partial membership rotation every three years. In addition to its formal membership, ACS60 maintains an active Friends list.
