transit_service_external_data

This data flow is used within the Manage Transit function. It contains transit services (routes, schedules and transfer points) in their raw form for distribution to and use by processes in other ITS functions. The map data of transit routes is included to enable output of displays showing transit routes by processes that do not have access to a digitized map database. Those that do can use the link identity in the transit routes data to map out the transit route. The data flow consists of the following items of data both of which are defined in their own DDE's:

transit_routes_data
+ transit_schedule_data
+ transit_transfer_cluster_list
+ trmc_list
+ map_transit_data
