Node-GTFS

node-GTFS loads transit data in GTFS format, unzips it and stores it to a MongoDB database. In addition, it provides some methods to query for agencies, routes, stops and times. It also has spatial queries to find nearby stops, routes and agencies.

Example Application

The GTFS-to-HTML app uses node-gtfs for downloading and querying GTFS data. It provides a good example of how to use this library.

Setup

You can clone from github:

git clone git@github.com:brendannee/node-gtfs.git

cd node-gtfs

npm install

or install directly from npm:

npm install gtfs

cd node_modules/gtfs

Configuration

Copy config-sample.js to config.js.

cp config-sample.js config.js

Before you can use gtfs-to-html you must specify the transit agencies you'd like to use.

You can specify agencies using a url to the GTFS file or a local path.

To find an agency's GTFS URL, visit transitfeeds.com. You can use the direct URL from the agency or you can use a URL generated from the transitfeeds.com API along with your API token.

Specify a download URL:

{
    agency_key: 'county-connection',
    url: 'http://cccta.org/GTFS/google_transit.zip'
}

Specify a path to a zipped GTFS file:

{
    agency_key: 'localAgency',
    path: '/path/to/the/gtfs.zip'
}

Specify a path to an unzipped GTFS file:

{
    agency_key: 'localAgency',
    path: '/path/to/the/unzipped/gtfs/'
}

The mongodb URI should also be configured in config.js. The default database URI is: mongodb://localhost:27017/gtfs

Loading Data

Make sure mongo is running

mongod

Run the download script

npm run download

node ./scripts/download

Scheduling

To keep schedules up to date, you could schedule this to occur once per day.

Querying data

You can include this library in your project to expose some functions for querying GTFS data.
