Runner jogging beneath vibrant green tree canopy along a sun-dappled park path

Urban heat-island pilot · Hacktoberfest

A concrete
heat island
should never end
the stride.

ArborStride watches street microclimates, predicts asphalt radiant heat, and finds a cooler route before direct sun becomes a heat hazard.

The moment that matters

Five minutes before asphalt heat exhaustion sets in.

A route navigator should not discover an unbearable heat island when the runner is already baking under direct sun.

12:15 PM

Run planned through downtown corridor

Conventional routing selects shortest distance along Broad Street commercial asphalt.

12:21 PM

TabPFN flags asphalt radiant heat spike (+11°F)

Zero tree cover on Broad Street produces 93°F ground temperature under peak solar angle.

Automatically rerouted through Elm Oak Archway

ArborStride AI redirects loop into 84% mature canopy. Temperature drops 8.1°F. Earbuds chime softly.

One incident. Four systems move.

The route is only as good as its physics.

ArborStride AI pairs open physical telemetry with tabular foundation models, local language reasoning, and eyes-free audio.

Source Watch

OpenStreetMap street geometries and live solar elevation angles monitor solar radiation exposure on real roads.

Prior Labs TabPFN

Zero-shot tabular foundation model predicts continuous street surface heat deltas and pavement thermal comfort with mathematical precision.

Google Gemma 2

On-device open-weight model synthesizes tabular physics into 15-word sensory waypoint scripts and a 3-bullet field briefing.

ElevenLabs Voice

Whispers turn cues into wireless earbuds so your phone stays in your pocket, making the screen the shortest part of the walk.

Our standard

Designed around nature, not notifications.

ArborStride AI does not ask walkers to trust a black box or stare at glass. It models real thermodynamics and gets out of the way.

Evidence before confidence

Every route segment displays its canopy percentage, predicted surface temperature, and tree species provenance.

Thermal comfort first

Routes are ranked around microclimate comfort and tree shading, not just the fastest asphalt commute.

Screen as the shortest part

15 seconds on screen before leaving. Once outdoors, OLED Pocket Mode and hands-free audio keep your head up and eyes open.
