ArborStride AI: Escape Urban Heat Islands with Open-Source Microclimate Routing

Description and use

ArborStride AI routes users through continuous tree canopies, reducing surface heat by up to 9 °F and providing a screenless audio‑guided experience.

Problem

Urban navigation apps prioritize fastest routes, steering walkers and runners through unshaded asphalt, exposing them to 10°F–15°F higher surface temperatures.

Outcome

ArborStride AI delivers thermally comfortable walking routes by prioritizing tree canopy coverage, reduces heat exposure by up to 9°F, and offers a screenless audio‑guided experience.

Workflow

• 1. Map continuous tree canopies using OpenStreetMap tree tags.
• 2. Predict microclimate thermodynamics with Prior Labs TabPFN‑v2 based on solar elevation, ambient temperature, humidity, canopy density, pavement albedo, and species type.
• 3. Compute edge costs as Distance × (1 – 0.65 × CanopyCoverage/100) × ThermalPenalty to favor shaded paths.
• 4. Generate 15‑word sensory waypoint prompts via Google Gemma 2.
• 5. Deliver turn‑by‑turn audio cues through ElevenLabs neural voice in OLED Pocket Mode.
• 6. Export GPX for Apple Watch, Garmin, and Strava.
• 7. Deploy on Vercel, Render, Docker Compose, or Railway with edge geolocation calibration.

Evidence

Standard navigation engines (Google Maps, Apple Maps) prioritize the fastest automotive or pedestrian path, funneling walkers, runners, and families through unshaded concrete canyons and baking parking lots.
