Edge Cost Updater
Software componentCognitionCognition & Memoryarc:EdgeCostUpdater
A cognition component that applies incoming environment-change observations (e.g., traffic travel-time estimates, detected blockages) as edge-cost changes to the state-space graph.
Responsibility. Updates state-space edge costs from new environment observations.
Also known as: Traffic cost updater, Map change detector
Relationships
reads dependency
writes dependency
triggers dynamic
Design guidance
- SHOULD propagate only cost changes exceeding significance thresholds (e.g., travel time +20% or -30%) to incremental replanning.
Quantitative guidance
As stated by the sources; verify before use.
- Connected-vehicle traffic updates arrive every 15 seconds in the autonomous vehicle scenario (Ch5.6).
