Current and forecasted traffic information, road and weather conditions, and other road network status. Either raw data, processed data, or some combination of both may be provided by this flow. Information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements) in effect is included.

roadway maintenance status  (Future)  Selected Comm Solution

Summary of maintenance fleet operations affecting the road network. This includes the status of winter maintenance (snow plow schedule and current status).

toll data  (Future)  Selected Comm Solution

Current toll schedules for different types of vehicles as well as advanced toll payment information.
