The fastest path ≠ safest path

treeroute maps 700,000+ NYC street trees to your allergy profile, then layers live pollen pressure, wind speed, and humidity to rank every route.

Register once, pick your triggers — oak, birch, maple — and the planner steers you through lower-burden corridors instead of just the shortest path.
