Camera Avoidance Overhaul

Major upgrade to FlockFree's camera avoidance routing system, implementing Phases 1-3 of the FlockFree avoidance roadmap.

New Features

Direction-Aware Camera Filtering

  • Cameras now only block road segments matching their facing direction (±60°)
  • Reduces over-blocking on divided highways and parallel roads
  • Falls back to omnidirectional blocking when bearing data is missing

User-Selectable Avoidance Modes

  • Warnings Only — Show cameras and alerts, never reroute
  • Balanced — Reroute with 15 min / 1.5x guardrails (default)
  • Strict Privacy — Reroute with 30 min / 2.0x guardrails

OSM Overpass Second Data Source

  • Nightly Overpass API pull for ALPR cameras from OpenStreetMap
  • Separate overlay table with deduplication
  • Configurable endpoint and refresh interval (default weekly)

Route Comparison Cards

  • Fastest vs Privacy options shown in route info menu
  • Shows camera count, time, and distance for each option

Improvements

  • Greedy incremental avoidance replaces block-all-then-relax algorithm
  • Severity-tier staged blocking
  • Route-association caching (LRU, 5-min TTL)
  • Active-navigation horizon planning (10km forward, 5s budget)
  • Dual-route motorway penalty
  • Manufacturer-based camera matching (OSM canonical tags)
  • 1.5x wider blocking radius vs scanning radius
  • FALLBACK status preserves comparison data

Known Limitations

Hard-block approach cannot steer router toward surface street alternatives when interstate is fundamentally faster. Weighted penalty approach (Phase 4) deferred.

Build

  • Signed with FlockFree release keystore
  • Target: arm64
  • Version: 5.4.0
