WeatherShare was developed by the Western Transportation Institute at Montana State University, and sponsored by the California Department of Transportation to improve weather related situation assessment, incident recognition, and response by providing streamlined access to surface weather data from multiple sources. The Phase II system covers all of California with emphasis on its more than 16,600 miles of state and federal highways and provides the most recent and forecasted weather information. The information is collected from over 3,200 surface weather stations from state and National weather sources such as Caltrans Road Weather Information Systems (RWIS), California Data Exchange Center (CDEC), MesoWest, NOAA’s Meteorological Assimilation Data Ingest System (MADIS) and the NOAA National Digital Forecast Database (NDFD). Three-level Quality Control (QC) procedures have been implemented to flag questionable sensor readings. Other value-added features include mapping NDFD data to California highway mileposts, and using combinations of data to detect and display alert conditions. In Phase 3, WeatherShare will become Caltrans’ repository for Caltrans RWIS data. As such, it will focus more on the needs of Caltrans personnel. Another Caltrans project, the One Stop Shop, has stepped in to provide travelers with important road and weather information. This division of roles will allow the two systems to better focus on the diverse needs of both travelers and maintence teams. |
