Uses of data

We have already seen a wide array of creative uses of transit-related open data into web- and smartphone-based applications since we published our GTFS data in 2013. Search for “Big Blue Bus” in the travel or navigation categories of your preferred app store (Google Play or the App store) to explore your options; many provide trip planning help and arrival times.
