L. No. 112 1412). MAP-21 authorizes the federal surface transportation programs for highways, highway safety, and transit.

The mission of the GTSB is to identify traffic safety problems and thereon develop and implement traffic safety programs designed to reduce death and injury on Iowa’s streets and highways through partnerships with local, county, state, and private sector agencies.
