UWTDC is a data repository for shared mobility data operated by the University of Washington. The concept is that data can be managed, protected, analyzed, and, where appropriate, shared, more efficiently and effectively by a single collaborative organization with a common set of policies and procedures.
The Weather Data Environment (WxDE) is an FHWA research project that collects and shares transportation-related weather data with a particular focus on weather data related to connected vehicle applications. The WxDE collects data in real time from both fixed environmental sensor stations and mobile sources. The WxDE computes value-added enhancements to this data, such as by computing quality-check values for observed data and computing inferred weather parameters from vehicle data (e.g., inferring precipitation based on windshield wiper activation).
