Intelligent Transportation Systems (ITS)



In the coming month’s travelers in the Dayton/Springfield area along I75, I70, I675, US35 and SR 49 will see 56 new traffic cameras, part of the Dayton/Springfield ITS project. These new cameras will allow the public to view how traffic is flowing before they leave their homes. Several Dynamic Message Signs (DMS) will be installed and a new HAR location will come online allowing the over the air broadcast of roadway times. All of these new devices will be accessible through Below you can find more information about the Intelligent Transportation System.

 Ohio ITS Vision Statement

Ohio will have an exemplary ITS program that combines technology and advanced operational concepts to improve transportation decision-making by all partner agencies, while providing unprecedented levels of information to businesses and individual travelers.

 What are Closed Circuit Television Cameras?

Closed Circuit Television Cameras are the cameras used to monitor the activity on major roadways across Ohio. Most cameras are equipped with pan/tilt/zoom capabilities, which allow the TMC operators to rotate the cameras and zoom in for a closer look at what’s going on. The cameras are primarily used to view any roadway incidents or accidents that occur so that a corresponding message can be posted on the DMS and/or broadcast on HAR.

 What are Dynamic Message Signs (DMS)?

Dynamic Message Signs (also called Variable Message Signs) are the large, electronic signs which overhang or appear along major highways in many Ohio metropolitan areas. The signs are typically used to display information about traffic conditions, travel times, construction, and road incidents. Travel time information is the default message that appears on a DMS daily from 5:00 A.M. to 9:00 P.M.  The signs are also used overnight if needed for construction, road incidents, or other relative information.  The signs are not used for public advertisements, weather information, or any other type message unless approved by a statewide or nationwide campaign.


 Highway Advisory Radio (HAR)

Highway Advisory Radio is basically an audio version of a DMS. HAR broadcast locations are marked by signs as shown to the right. By tuning into the specified radio station, you can hear information regarding traffic conditions, travel times, construction, road incidents, missing persons, and other information deemed relevant to motorists.  Signing for HAR’s generally tells the motorist to tune into the correct AM frequency for 24/7 traffic information and also has flashing beacon lights for traffic alerts.  When the beacons are flashing, there is a traffic alert, therefore motorists are advised to tune into the appropriate AM station.

 Statewide Traffic Management Center (TMC)


The Ohio Department of Transportation’s (ODOT) Statewide TMC operates traffic management and traveler information systems on Ohio’s interstates, freeways, expressways, and state highways.  The mission of the TMC is to increase transportation safety, reduce congestion, and increase efficiency on Ohio’s state highways.

The Statewide Traffic Management Center is located in Columbus, OH at the Ohio Department of Transportation’s Central Office.  The TMC has dedicated operators who monitor traffic in each major metropolitan area across the state including Akron/Canton, Cincinnati/Northern KY, Cleveland, Columbus, Dayton/Springfield, and Toledo. 

The operators can control cameras, post messages to DMS, HAR, and the Buckeye Traffic website, etc.


 Traffic Speed Sensors

Buckeye Traffic receives updated traffic speed data from remote sensors approximately every minute. The sensors provide average speeds for each direction of the roadway. They do not report individual speeds and are not used for law enforcement.  The speeds are color-coded and represented on the speed display map.
