1.1 Pre-trip Travel Information (User Service*)
The Pre-Trip Travel Information user service allows travelers to access a complete range of real-time multimodal transportation information at home, work, and other major sites where trips originate. Information on road network conditions, incidents, weather, and transit services, are conveyed through these systems to provide travelers with the latest conditions and opportunities in order to plan their travel. Based on this information, the traveler can select the best departure time, route and modes of travel, or perhaps decide not to make the trip at all.
