GTFS (General Transit Feed Specification) Database

Python code that will load GTFS data into a relational database, and SQLAlchemy ORM bindings to the GTFS tables in the gtfsdb. The gtfsdb project's focus is on making GTFS data available in a programmatic context for software developers. The need for the gtfsdb project comes from the fact that a lot of developers start out a GTFS-related effort by first building some amount of code to read GTFS data (whether that's an in-memory loader, a database loader, etc...); GTFSDB can hopefully reduce the need for such drudgery, and give developers a starting point beyond the first step of dealing with GTFS in .csv file format.

(Slightly out-of-date version) available on pypi: https://pypi.python.org/pypi/gtfsdb

Install from source via github (if you want the latest code) :

1. Install Python 3.x https://www.python.org/downloads/ (code also runs on 2.7 if you are stuck on that version)

2. pip install zc.buildout - https://pypi.org/project/zc.buildout

3. (optinal step for postgres users: 'pip install psycopg2-binary')

4. git clone https://github.com/OpenTransitTools/gtfsdb.git

5. cd gtfsdb

6. buildout install prod -- NOTE: if you're using postgres, do a 'buildout install prod postgresql'

7. bin/gtfsdb-load --database_url <gtfs file | url>

   examples:

   • bin/gtfsdb-load --database_url sqlite:///gtfs.db gtfsdb/tests/large-sample-feed.zip
   • bin/gtfsdb-load --database_url sqlite:///gtfs.db http://developer.trimet.org/schedule/gtfs.zip
   • bin/gtfsdb-load --database_url postgresql://[email protected]:5432 --is_geospatial http://developer.trimet.org/schedule/gtfs.zip

   NOTE: adding the is_geospatial cmdline flag, when paired with a spatial-database ala PostGIS (e.g., is_spatial is meaningless with sqllite), will take longer to load...but will create geometry columns for both rendering and calculating nearest distances, etc...

8. view db ( example: https://sqliteonline.com )

The best way to get gtfsbd up and running is via the 'zc.buildout' tool. Highly recommended to first install buildout (e.g., pip install zc.buildout) before doing much of anything else.

Postgres users, gtfsdb requires the psycopg2-binary database driver. Installing that via pip install psychopg2-binary will relieve gtfsdb from re-installing locally as part of the build. And if after the fact, you see exceptions mentioning "ImportError: No module named psycopg2", then 'pip install psychopg2-binary' should fix that up quick...

Example Query:

-- 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
