Improve road weather monitoring by integrating environmental sensor stations (ESS) on 17 bridge decks that measure a range of weather–related conditions, including pavement temperature and status (wet, dry, snow), subsurface pavement temperature, wind speed and direction, precipitation (amount, occurrence, type), water level conditions, humidity, and visibility with the Tollway's Traffic and Incident Management System (TIMS). In–pavement sensors are being replaced with non–intrusive, highly accurate laser sensors for bridge pavement condition and advanced detection of water, ice, snow and slush thickness as well as surface grip (slipperiness).
Weather data collected by agencies allows them to coordinate the pre–treating of roads via anti–icing practices; efficiently plan winter maintenance routes; reduce the amount of chemicals, sand, and salt used in roadway clearing operations; and reduce wear and tear on maintenance vehicles. This information can also be disseminated along with other incident data as real time transportation information.
