ODOT Brings Latest Road Weather Data to the Web

Columbus - The Ohio Department of Transportation announced today the first release of Road Weather Information System (RWIS) data on the ODOT Website. The statewide RWIS is an automated million-dollar system of 244 pavement sensors and 72 Remote Processing Units that track conditions of the actual driving surface, air temperature, wind speed, direction, precipitation and other weather conditions. The first phase of bringing this data to the Web involves selected data from 34 weather stations and 98 pavement sensors located on State routes scattered throughout Northwest Ohio. The Remote Processing Units report conditions every hour.

The purpose of the system is to provide accurate, timely, and reliable information. ODOT uses information from RWIS to help determine the precise time to chemically treat highways for snow and ice control. Determining the proper time to apply chemical treatments can greatly reduce labor and material costs. For instance, if heavy snowfall occurs on pavement that is 50 degrees Fahrenheit, it could be several hours before chemicals need to be applied (or none may be needed at all) because the snow melts on contact with the warm highway surface.

RWIS data is currently available in the following areas: Toledo, Akron, Columbus, Cleveland and Cincinnati. This initial offering to the public includes only counties in the Toledo area (ODOT District 2): Williams, Fulton, Henry, Wood, Lucas, Ottawa, Sandusky and Seneca.
