Federal Highway AdministrationFederal Highway AdministrationThe Weather Data Environment (WxDE) collects and shares transportation-related weather and road condition data from across the United States for Transportation System Management and Operations (TSMO) and connected vehicle applications. Data is collected in real time from fixed environmental sensor stations and mobile vehicular sources. It checks the quality of the observed data and can infer additional road weather conditions from vehicle data such as precipitation from windshield wiper activation and radar data. The WxDE archives both collected and computed data. Real-time data can be browsed on a map, queried for a report, or subscribed to as a data feed.78
