Operational Design Domain (ODD) Analysis

Challenges

  • Is a proposed Target Operating Domain (TOD) suitable for AV operation?

  • Will modifications to the PDI, AV design, or operational management make the proposed TOD suitable for AV operation?

These questions can only be answered by detailed ODD analysis, and followed by rigorous systems engineering.

Our approach

  • The ODD is described in detail following ISO34503.

    • Scenery elements (e.g., road/drivable area types)

    • Environmental conditions (e.g., weather, illumination)

    • Dynamic elements (e.g., traffic)

  • Our ODD and Route Analysis (ORA) tool provides assisted and fully automated capabilities to create a comprehensive definition of the ODD and identify hazards for a given route.

  • The expected AV behaviours and undesirable AV behaviours are organised in a structured matrix approach according to identified hazards.

  • Our Behaviours Matrix (BM) supports objective test criteria.

Benefits

  • Leads to large portion of AV requirements definition.

  • Supports identification of ODD hazards to AV operation.

  • Provides range bounds and distributions for design verification plans.

  • Supports verification acceptance criteria definition.
