Inspiration

Parents and asthmatic commuters do not need another map. They need to know if this jam is worth sitting in — for their lungs and for wasted fuel. Congestion is an air problem and a climate problem you can act on today.

What it does

JamBreath turns live traffic into an Earth Forward impact readout:

• Pulls TomTom routing + flow-segment speeds
• Measures delay vs free-flow
• Estimates idle CO₂ from delay (transparent ESTIMATE, 20 g/min mid factor)
• Samples corridor AQI (Open-Meteo)
• Suggests a healthier move (alternate route or leave later) and logs avoided impact

How we built it

TypeScript + Vite front end. TomTom Search/Routing/Traffic when a key is present; realistic fixture mode for judges without credentials. Open-Meteo for AQI. GitHub Pages for a one-click demo.

Challenges

Keeping claims honest (idle CO₂ labeled ESTIMATE, not a full LCA), and making the live-traffic path work with a clean fixture fallback so cold judges still get a full demo in under a minute.

What's next

Richer corridor sampling, optional domain-whitelisted live key for the public demo, and a short pitch video of the judge path.
