WisDOT Improves Winter Road Conditions Map | Weather News


MADISON (WKOW) – The Wisconsin Department of Transportation has updated 511wi.gov to expand and improve winter road conditions.

From Monday, more than 14,000 miles of roads will be updated at least twice an hour by devices pulling data. Previously, only 3,700 miles were covered by field observation and could only be updated every few hours.

According to a news release from WisDOT, the Maintenance Decision Support System (MDSS) counties used to schedule tillage and salting will provide data for the road condition map. The MDSS generates models for the report based on the following data points:

Atmospheric and road weather sensors along the roadway and at airports

Information from snowplows enabled with Geographic Information Systems (GIS)

Information from the National Weather Service.

“Safety is at the heart of our mission,” WisDOT Secretary Craig Thompson said in the statement. “We pride ourselves on finding new ways to leverage technology to improve service and give the public a clearer and more accurate idea of ​​how to prepare for the road ahead.”

WisDOT began cataloging road conditions online in 2013, with staff manually reporting conditions in the field. Using MDSS technology, WisDOT can update conditions with greater consistency.

In the release, WisDOT recommended taking the following steps before driving in winter:

Visit 511wi.gov online or download the 511wi smartphone app.

In the map legend, make sure “winter road conditions” is checked.

Look for the colors describing the roads near you.
