1.4.7 Route Instructions List ADT

Route Instructions List ADT contains a list of travel instructions consisting of turn-by- turn directions and advisories along the route, ordered in sequence of their occurrence, and formatted for presentation to the user. Route Instructions List ADT is generated by the Route Service and “presented” to a subscriber via the Presentation Service.

1.4.8 Route ADT

The Route ADT is actually two ADTs: Route Summary and Route Geometry. Route Summary contains the route’s overall characteristics, such as its start point, waypoints, end point, transportation type, total distance, travel time, and bounding box. Route Geometry contains a list of geographic positions along the route, ordered in the sequence of planned travel, starting with the position of the route’s origin and ending with the position of the route’s destination. The geometry includes the positions of all nodes along the route, including waypoints. The geometry also includes intermediate points needed to describe the geometric shape of the route segments between each node in the route. These two ADTs are generated by the Route Service and “presented” to a subscriber as routing information, e.g. as a route displayed over a map, via the Presentation Service, or they are used directly by an application to guide a mobile subscriber to their destination.
