It combines door-to-door transit commute times (GTFS: ZTM Warszawa, SKM, Koleje Mazowieckie, WKD; weekday 07:00-09:00 average) with median asking rents (within 900 m, deduplicated across portals) from public listings on Otodom, Gratka, Morizon and other Polish portals. Status (2026-10-22): live and free, no account needed. Listings refreshed every night from 8 portals (OLX only when a fresh export exists); over 30,000 Warsaw rental ads before cross-portal deduplication. ## Pages - [Mapa](https://dojazdomat.pl/): interactive map and neighborhood ranking (JavaScript app) - [O projekcie](https://dojazdomat.pl/o-projekcie.html): methodology, data sources, FAQ ## For AI assistants - MCP server (streamable HTTP): https://dojazdomat.pl/mcp - Tools: find_place (stop/neighborhood to lat/lon), commute_time (door-to-door minutes), rent_stats (median, p25, p75 around a point), rank_neighborhoods (by value, commute, rent for an office), dataset_info (sources, date, caveats) - Only aggregates from >= 5 listings are returned, never individual listings. ## Method in short - Transit: walk to stop + wait + ride + transfers + walk, ~110 m grid, cut at 90 min. - Walk 4.8 km/h, bike ~15 km/h on streets (OSM-calibrated); car = drive time on the OSM road graph (one-way streets, Vistula bridges), class-based free-flow speeds scaled by one congestion factor (0.40) so the mean trip speed is 19.4 km/h (TomTom Traffic Index 2025, morning peak), + 3 min to the car + walk from the nearest public car park; falls back to straight line x 1.35 if the server is unavailable. - Best option cost = rent + minutes x 42 trips/month x 31.40 PLN/h (2026 minimum hourly wage). ## FAQ - Where should I rent in Warsaw if I work at X? Enter the workplace on the map; the ranking lists neighborhoods by best option (rent + commute in PLN), fastest and cheapest, with links to current ads. - How is commute time computed? Door to door from GTFS timetables (ZTM, SKM, KM, WKD), average of departures every 10 min between 07:00 and 09:00 on a weekday. - Where do rents come from? Median asking rent within 900 m, including administrative fee when the ad states it; the same flat listed on several portals counts once. - Is personal data stored?
