The Ohio Department of Transportation (ODOT) plays a central role in developing, maintaining, and operating state roads and highways, ensuring both mobility and safety for Ohio’s roadway users[1]. The department is responsible for all state and US roadways outside municipalities, as well as all Interstates except the Ohio Turnpike[1].
To monitor and manage traffic conditions, ODOT operates a Statewide Traffic Management Center (TMC) based in Columbus. The TMC is staffed 24/7 and utilizes cameras and speed sensors to observe traffic flow throughout Ohio’s major metropolitan areas. Operators post real-time incident updates to OHGO.com and highway message boards, and are also tasked with managing specialized corridors such as the I-90 Variable Speed Corridor in Lake County and the I-670 SmartLane in Columbus[1].
The TMC supports Ohio’s transportation system by:
- Providing real-time traveler information via OHGO, the state’s official platform for traffic updates
- Operating and monitoring roadside devices, including over 1,300 traffic cameras, overhead message boards, variable speed limit signs, and queue warning systems
- Delivering up-to-date information on traffic conditions, incidents, travel delays, and weather-affected roadways
- Offering personalized route alerts and warnings about construction or sudden slowdowns
Motorists can access these services through the OHGO website or mobile app to plan their travel more efficiently[2][3].
ODOT’s Office of Transportation Systems Management & Operations (TSMO) oversees various programs that keep traffic moving safely and reliably, including the TMC, the Traffic Incident Management program, and statewide traffic signal operations[4]. The Office of Traffic Operations provides engineering expertise for permanent and temporary highway conditions, supports intelligent transportation systems, and maintains standards and training for traffic safety across the state[6].
In addition to real-time traffic management, ODOT collects and analyzes traffic data using automated recorders and crash databases, often in partnership with the Ohio Department of Public Safety. This information guides traffic engineering decisions, establishes safety standards, and helps direct maintenance and improvement efforts[1].
