Open Data Award · Madrid City Council 2025

Find routes your wheelchair, walker or stroller can actually use.

For older adults, reduced mobility, post‑surgery recovery and families with strollers — in Madrid and Valencia.

A city you can’t move through is a city you don’t fully live in.

Google Maps and Apple Maps optimise for the fastest path. They don’t measure whether a sidewalk is wide enough for a wheelchair, whether there’s a kerb step or if the surface is poor. Rampa does.

We combine open municipal data — OpenStreetMap, sidewalk inventories, urban infrastructure — with deep learning that infers real width, slope and surface per segment. The result is a street graph with meaningful accessibility, powering our routing engine.

How it works

  1. We measure every sidewalk

    We cross municipal open data with OpenStreetMap and ML models to recover real width, slope, kerb drops and surface quality per segment.

  2. We combine obstacles and slope

    Our engine weighs width, slope, obstacles and surface to assign a real accessibility cost — not a generic guess.

  3. The accessible route, not only the shortest

    You see both options — fastest vs most accessible. On the accessible path, each segment is labelled so you know exactly where you’re going.

Same start. Same destination. Different path.

Shortest route vs accessible route

Shortest route
  • Sidewalks under 90 cm on 3 segments
  • Slope >8 % on one street
  • No kerb ramp at the main crossing
Rampa route
  • Sidewalks ≥ 1.5 m on all segments
  • Max grade 4 % — wheelchair‑friendly
  • Kerb drops at every crossing
