This data flow is used within the Manage Traffic function and contains data about each segment in the highway network and the way in which they fit together, i.e. which segment is joined to which, both upstream and downstream, plus identification of those links that interface to the road (surface street) network. It consists of the following data items each of which is defined in its own DDE:

+ list_size{route_segment_downstream_identity
+ route_segment_end_point
+ route_segment_identity
+ route_segment_start_point
+ route_segment_upstream_identity
+ turning_movements}
