HCAS Study Review Team

The Study Review Team (SRT) consists of outside experts knowledgable about transportation policy. It includes experts working for interested parties such as the trucking industry and AAA. The team is chaired by the State Economist. The SRT's main functions are to identify key issues to be studied and to review the contractor's analysis and work products. The SRT meets approximately eight times during each biennial HCAS report cycle and receives no compensation for their service.

The SRT:

Selects the contractor to conduct the study
Reviews the contractor's final work plan
Provides policy direction to the study
Reviews the contractor's work elements
Reviews the draft study
