1 Definition

A Route is a sequence of Way Points on an Offline Map, each associated with an Estimated Start Time and an Estimated Arrival Time. A Route may also record the Actual Arrival and Departure Times and the corresponding Places where the CAV has stopped or slowed down. The Route serves as a high‑level representation of the plan followed by the CAV and the actual progression of the CAV across the Offline Map.

2 Functional Requirements

A Route shall consist of an ordered series of Way Points forming a path across a specified Offline Map. Each Way Point shall include:

  • An identifier linking it to the Offline Map.
  • Estimated Arrival and Departure Space/Time.
  • Actual Arrival and Departure Space/Time.
  • The local Road State at the Way Point.

The AMS may use Route data to:

  • Validate motion planning consistency against the Offline Map.
  • Analyse timing deviations between estimated and actual behaviour.
  • Record historical operational performance (e.g., stop locations, delays).

DescrMetadata string Human-readable descriptive metadata of the Route (plain text, max 2048 characters).

5 Conformance Testing

Data conform to the Route Data Type when they validate against its schema. If the schema references other schemas, data referencing a secondary schema shall also validate against that schema, if present, and conform with the Qualifier, if present.
