511 Wisconsin provides up-to-date winter road conditions

511 Wisconsin provides up-to-date winter road conditions
WisDOT travel information system keeps drivers better connected and informed

The Statewide Traffic Operations Center (STOC) in Milwaukee and law enforcement agencies statewide are working closely to update winter road conditions and inform the commuting public through overhead message signs and the 511 Wisconsin travel information system.

The data collected for road conditions comes from human reporting – law enforcement, county officials and other officially approved individuals physically traveling the roads and assessing their condition. The person’s assessment of the road condition is then reported to State Patrol dispatchers who enter this information and populate the 511 Wisconsin system.

Winter weather is a perfect reason to take advantage of the free 511 Wisconsin smartphone app or follow @511WI on Twitter. Users can receive notifications of winter weather warnings, view over 400 traffic cameras, and see road conditions statewide. Always putting safety first, never access 511 information while driving. Either safely pull off of the highway, or have a passenger check it.
