About the STOC
The WisDOT Statewide Traffic Operations Center (STOC) handles traffic management for the state of Wisconsin. Highly skilled control room operators use state-of-the-art technology to monitor and improve the safety and efficiency on the state freeway system by reducing incidents and relieving traffic congestion.
The STOC is staffed 24 hours per day, 7 days per week. Control room staff communicate regularly with sheriff, fire, police, and Wisconsin State Patrol, as well as media outlets and construction project managers.
- Detailed information about current travel conditions and times in urban regions enable travelers to make informed decisions about how they travel.
- Agencies are able to respond faster and more efficiently to interruptions in travel caused by emergencies, accidents, breakdowns, weather and increased congestion.
- Reduced congestion improves air quality, decreases noise pollution and lowers fuel consumption.
- Trucks and other commercial vehicles are able to move through urban regions with minimal delays, helping the freight industry maintain lower costs to consumers.
