SafeRoute

Walk the lit path. A mobile-first women's safety map of Delhi — rate how safe a street feels, see the city as a live safety heatmap, compare routes by safety as well as speed, and share your location with trusted contacts in one tap.

Why I built this

"Is this route safe?" is a question maps don't answer — they optimize for fastest, not safest. SafeRoute treats safety as a first-class routing signal by fusing two data layers: official NCRB crime statistics for the baseline, and crowd-sourced street-level ratings for what the data misses — lighting, crowds, CCTV, the things you only know by being there. Every walking route is scored on both, so "safest" and "fastest" sit side by side and the choice is yours.

Features

• Crowd-sourced safety ratings — tap anywhere on the map to rate a spot (1–5), with lighting / crowd / CCTV tags and an optional note.
• Safety heatmap — every rating feeds a live heatmap of safe corridors and dark stretches.
• Area safety + crime map — your current district's official NCRB crime statistics, plus a dark map view with districts glowing gold by reported crime (bundled data; labeled clearly as annual official data, not real-time).
• Route comparison — pick a destination and compare OSRM route alternatives, each scored from nearby ratings and district statistics: safest vs fastest, side by side.
• One-tap SOS — shares your exact location with your emergency contacts via the system share sheet or WhatsApp.
• Google sign-in — ratings and contacts are tied to your account; contacts are private to you, enforced by Postgres row-level security.

Stack

React 18 · TypeScript · Vite · Tailwind CSS · Leaflet + leaflet.heat · Supabase (auth, Postgres, RLS) · OSRM routing · Photon geocoding · NCRB data via data.gov.in

Setup

1. npm install
2. Copy .env.example to .env and fill in VITE_SUPABASE_URL / VITE_SUPABASE_ANON_KEY from your Supabase project's API settings.
3. In Supabase, enable the Google auth provider and apply supabase/migrations/000_init.sql.
4. npm run dev

Notes

• Routing uses the FOSSGIS public OSRM foot profile — walking routes and walking ETAs.
• Map tiles, routing, and geocoding endpoints are all overridable via env (VITE_TILE_URL, VITE_TILE_URL_DARK, VITE_TILE_ATTRIBUTION, VITE_OSRM_URL, VITE_PHOTON_URL — see .env.example), so moving to commercial or self-hosted providers at scale is a config change, not a code change.
• Crime statistics are district-level and annual (NCRB 2015 via data.gov.in, bundled as static JSON in src/data/). They are a baseline signal; crowd ratings are the live layer.
