Risk segments ingest DGT's official DATEX2 feed of high-risk motorcycle segments and store them in PostGIS. When you submit a route, a spatial intersection query (ST_Intersects) returns every flagged segment your route crosses, with road badge, province, and kilometrage.
Real road geometry snaps routes to actual roads via a self-hosted OSRM instance built from OpenStreetMap data covering mainland Spain and the Canary Islands, merged into a single routing graph. Waypoints snap to the nearest road on click. No straight lines between clicks.
Route modes let you bias each segment's geometry between speed and curvature. Fast uses OSRM's default driving profile, motorways included. Balanced and Curvy both exclude motorways and ask OSRM for three alternatives: Balanced picks the route with the best curvature-per-kilometre ratio (sinuous without taking the long way round), while Curvy picks the most sinuous one regardless of extra distance. Curvature is scored on the server as the sum of bearing deltas along the geometry, normalised by route length. If no non-motorway route exists, the request falls back to the direct one.
Weather samples the route at 50 km intervals and queries Open-Meteo for wind speed, precipitation, and visibility at each point. Supports forecast lookup up to 7 days ahead with per-hour resolution. Alert conditions (wind > 50 km/h, precipitation > 0.5 mm, visibility < 1 km) are flagged on both the map and the elevation profile.
Elevation profile samples the route geometry and queries the Open-Meteo Elevation API (Copernicus DEM GLO-90, 90 m resolution) to render an interactive profile chart with min/max altitude, cumulative gain, and weather alert markers.
Routes are built waypoint by waypoint. Click the map or search for a place by name. Each new point snaps to the nearest road and a new segment is fetched from OSRM. Waypoints can be dragged on the map to adjust the route, reordered in the sidebar by dragging the handle, or deleted individually. Inserting a stop between two existing waypoints is also supported, up to a maximum of 10 waypoints per route.
The search box uses Photon for forward geocoding and reverse geocoding for human-readable names when dropping a pin. Keyboard navigation works throughout: arrow keys move through results, Enter selects, Escape cancels. Device geolocation is available via the location button in each slot.
A circular mode closes the route back to the starting point, useful for loop rides. The reverse button flips waypoint order and rebuilds all segments in parallel, so the map updates all at once rather than one segment at a time.

POST /route/segments → ST_Intersects(route, risk_segments) on PostGIS
POST /route/weather → Open-Meteo hourly/current forecast per sampled point
POST /route/elevation → Open-Meteo Elevation API (Copernicus DEM GLO-90)
POST /route/snap → OSRM nearest: snaps a point to the road network
POST /route/geometry → OSRM route: road geometry between two points
POST /route/geocode → Photon forward geocoding (place name to coordinates)
POST /route/reverse → Photon reverse geocoding (coordinates to place name)
GET /health → liveness check
After the user draws a route, the frontend fires /route/segments, /route/weather, and /route/elevation in parallel via Promise.all. Road-snapping and geometry fetching go through the backend so OSRM is never exposed publicly. Open-Meteo responses are cached in an LRU memory cache (elevation: no expiry, weather: 10 min TTL, max 1000 entries) to avoid redundant requests.
The core query. With a GiST index on geom, this runs in milliseconds across the full national dataset:
SELECT id, road, province, direction, length_m, pk_start, pk_end,
ST_AsGeoJSON(geom)
FROM risk_segments
WHERE ST_Intersects(
geom,
ST_SetSRID(ST_GeomFromText($1), 4326)

nginx serves the app with a full set of security headers (HSTS, CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy). The Leaflet scripts loaded from unpkg.com have SRI integrity hashes so any tampered file gets blocked by the browser. The API enforces a 30 req/min per-IP rate limit at the nginx layer and a 1 MB body size cap on all POST endpoints. CORS origin is configurable via CORS_ORIGIN so the production deployment only accepts requests from motorisk.app.
- DGT data covers the national road network only (excludes Catalonia and the Basque Country for most datasets).
- OSRM map matching uses the
carprofile, appropriate for motorcycles on paved roads. - Weather sampling is at 50 km intervals; conditions between points are not interpolated.
- Elevation resolution is 90 m (Copernicus DEM GLO-90).

Herramienta de análisis de rutas para motoristas en España. Traza una ruta en el mapa y obtén los tramos de alto riesgo de la DGT, la geometría real de la carretera vía OSRM, las condiciones meteorológicas y un perfil de elevación interactivo.
Disponible en motorisk.app
Ver sección Screenshots más arriba.
Tramos de riesgo ingesta el feed DATEX2 oficial de la DGT de tramos de elevado riesgo para motocicletas y los almacena en PostGIS. Al enviar una ruta, una query de intersección espacial devuelve cada tramo señalizado que cruza tu ruta, con el nombre de la carretera, la provincia y el punto kilométrico.
Geometría real de carretera ajusta las rutas a carreteras reales mediante una instancia self-hosted de OSRM construida con datos de OpenStreetMap para la península y las Islas Canarias, fusionados en un único grafo de routing con osmium. Los waypoints se snapean a la carretera más cercana al hacer click. OSRM no está expuesto públicamente; el backend actúa como proxy.
Modos de ruta permiten elegir el compromiso entre rapidez y curvatura para cada segmento. Rápida usa el perfil de conducción por defecto de OSRM, autopistas incluidas. Equilibrada y Curvas excluyen autopista y piden tres alternativas a OSRM: Equilibrada se queda con la de mejor ratio curvatura/kilómetro (sinuosa sin alargarse de más), mientras que Curvas elige la más sinuosa en absoluto, independientemente de la distancia extra. La curvatura se calcula en el servidor como la suma de variaciones de rumbo a lo largo de la geometría, normalizada por la longitud de la ruta. Si no existe alternativa sin autopista, se cae a la ruta directa.
Construcción de rutas funciona punto a punto: cada waypoint puede añadirse haciendo click en el mapa o buscando un lugar por nombre mediante geocodificación con Photon. Los waypoints se pueden reordenar arrastrando, borrar individualmente, o editar para insertar una parada intermedia, hasta un máximo de 10 por ruta. El modo circular cierra la ruta sobre el punto de origen. El botón de invertir reconstruye todos los segmentos en paralelo.
Meteorología muestrea la ruta cada 50 km y consulta Open-Meteo para obtener velocidad del viento, precipitación y visibilidad. Permite consultar el forecast hasta 7 días vista con resolución horaria. Las alertas se marcan en el mapa y en el perfil de elevación.
Perfil de elevación muestrea la geometría de la ruta y consulta la API de elevación de Open-Meteo (Copernicus DEM GLO-90, resolución 90 m) para renderizar un gráfico interactivo con altitud mínima/máxima, desnivel acumulado y marcadores de alertas meteorológicas.
