TABs primarily are advisory by nature, and they typically are appointed by county commissioners to serve as a liaison between local governments and the transportation system. Some TABs, but not most, may actually create policies for their transportation system. Most TABs make advisory decisions and final approval for policy issues is reserved for determination by the county commissioners. However many policy and funding issues, such as grants, are first approved by the TAB, which then will make a formal recommendation to the county commissioners. TABs which are established for new community transportation programs are expanded to represent more elements of the community and be more inclusive of all groups within the community.
Many TABs meet monthly or quarterly.
The local transportation coordinator, who normally works for the county or the transportation system, assists the advisory board and provides statistical information about operations and finances. The coordinator also provides a mechanism by which the transportation system can vocalize important issues or concerns. The advisory board assists the TDP steering committee with the development of goals and objectives, reviews technical memorandums which may be prepared by outside consultants, provides initial approval of the TDP and makes recommendations for the TDP's approval to the county commissioners. These may include services such as accounting, legal advising or contract maintenance for facilities and vehicles. While numerous legal, regulatory and economic issues can complicate formal public- private partnerships, there also are considerable benefits.
