Open data is the free sharing of data for everyone to use and republish with few restrictions. GRT provides route, stop and schedule data for the purposes of developing applications to promote the use of transit and transit-related information.
GRT schedule data is published using the Google Transit Feed Specifications (GTFS). Route and stop location data is published using ArcGIS.
By downloading or using the data on the Open Data Portal, you are agreeing to the terms of the Region's Open Data Licence.
