ODOT District One Traffic Studies and Contact Information

District One Planning does many studies in this area.  Many traffic studies are done at the request of people and agencies outside of the Ohio Department of Transportation (ODOT).  Other studies are done due to an ODOT determined need.  Traffic studies are made for intersections and non-intersection roadway segments to determine what if any improvements should be made to improve safety and the operation of the road.  The need for traffic signals and speed zones are also determined by studies in this area.  Various other types of traffic studies, such as for traffic management in work zones, are also performed.
