Deprecated

TL;DR This gem is deprecated and will no longer be maintained. You should source data from the Queensland Government.

This project was created to source public transport data for South-East Queensland. The Queensland Government has since released the data on their own website under a liberal license. I encourage you to source your data from an officially supported source.

Translink

TransLink (Organisation) coordinates public transport operations in South-East Queensland. Their website has an abundance of data with no easy way for a developer to query it.

Translink (Program) scrapes bus routes, trips, stops and times into a relational database. The schema is a subset of the General Transit Feed Specification. Data is sourced from the TransLink website.You should be aware their data is protected by copyright.

Translink (Program) was created to provide data for my iOS app, Next Stop.

Queries

Stops the 130 visits on the outbound trip.

SELECT stops.*, stop_times.*
FROM routes
INNER JOIN trips ON trips.route_id = routes.route_id
INNER JOIN stop_times ON stop_times.trip_id = trips.trip_id
INNER JOIN stops ON stops.stop_id = stop_times.stop_id
WHERE routes.short_name = '130' AND trips.headsign = 'outbound'
GROUP BY stops.stop_id
ORDER BY stop_times.stop_sequence;

Routes that visit the 'Calam Rd near Honeywood St' stop.

SELECT DISTINCT(routes.short_name) FROM stops
INNER JOIN stop_times ON stop_times.stop_id = stops.stop_id
INNER JOIN trips ON stop_times.trip_id = trips.trip_id
INNER JOIN routes ON routes.route_id = trips.route_id
WHERE stops.stop_name = 'Calam Rd near Honeywood St';
