This scope of work describes the fourth phase in a multi-phase research project aimed at combining functionality of WeatherShare, SCAN Web^TM and SCAN Sentry^TM into a single, open system. This phase continues the research and development conducted previously to develop the system. Specifically in this phase the project team will continue work on the retrieval, storage and presentation mechanisms, and will develop the alerting and user profile mechanisms for the system. The project team will work with Caltrans to test and evaluate the system during the bad weather season.

The project is conducted through the Western States Rural Transportation Consortium (WSRTC). The WSRTC is comprised of the states of California, Oregon, Washington and Nevada, and has been established to facilitate and enhance safe, seamless travel throughout the western United States.
