CDTC maintains several ongoing advisory committees which serve to provide CDTC's Policy Board and Planning Committee with in depth technical information on topics of particular interest or concern. The advisory committees are guided by CDTC's staff and serve as a forum for the exchange of ideas, practices and progress reports about various initiatives taking place at National, State, regional and local levels. Advisory committees are also tasked with providing input to CDTC's Planning Committee and Policy Board on projects being evaluated for inclusion in the Transportation Improvement Program (TIP). Advisory Committees often meet quarterly but can meet monthly.
