To_Map_Update_Provider (Data Flow*)
This data flow is sent to the map update provider from several ITS functions. It contains requests for updates of the digitized map data used for display maps, as a navigable map database for on-vehicle or personal traveler guidance, and as a source of data for trip planning and transit route generation. The display map data is used as the background for the output of traffic, incident, maintenance and construction activities, transit services and pollution data, the guidance data is used for the guidance of drivers and travelers on their selected routes, while the trip planning data is used for routes produced in response to traveler's trip requests. Static data is sent to the map update provider for use in preparing the actual digitized map data. Request for data to be imported into the Manage Archived Data function is included in this data flow along with the status that is returned to the terminator when the data is imported. The data flow also includes data collected by field equipment from traffic probes on vehicles. The data flow consists the following data items each of which is defined in its own DDE:
