Query GTFS data with SQL.
Write GTFS data to Postgres(PostGIS) database running in Docker container using gtfsdb.
Build a Docker image after cloning the repo:
docker build -t gtfsdb2pg .
Start a container running in localhost:5432. Replace MY-GTFS-ZIP-URL with your GTFS data.
docker run -it -p 5432:5432 --name gtfsdb2pg -e GTFS=MY-GTFS-ZIP-URL gtfsdb2pg
Access the data in localhost:5432 with you're favorite DB tool. Or you can view it with psql:
docker exec -it gtfsdb2pg psql postgres postgres
-- get first stop time of each trip for route_id 1
select * from trips t, stop_times st where t.route_id = '1' and t.trip_id = st.trip_id and st.stop_sequence = 1
-- get agency name and number of routes
select a.agency_name, a.agency_id, count(r.route_id) from routes r, agency a where r.agency_id = a.agency_id group by a.agency_id, a.agency_name order by 3 desc
