Remote weather-sensing stations keeping watch over condition of NJ roads

Continual winter snowstorms have been plaguing New Jersey’s roads this season, resulting in the state Department of Transportation deploying a variety of technologies and personnel to combat the storms. One set of tools is the 37 remote roadway-weather-sensing stations deployed around the state, allowing unmanned technology to keep crews informed of conditions.

New Jersey also uses 164,000 tons of salt, 716,000 gallons of liquid calcium, and 150,000 gallons of brine solution to treat roads. These resources are stored in 68 maintenance yards around New Jersey. The road crews consist of both full-time employees and contractors.

All of it costs money. Through January 8, the state had spent more than $42 million on materials alone. During the 2012-2013 season, the state spent about $62 million on salt, liquid calcium, and brine.
