Västtrafik is the agency responsible for public transport services involving buses, ferries, trains, and the Göteborg tramway in the county of Västra Götaland, Sweden. Until 31 December 2011 the ownership was shared equally between the Västra Götaland Regional Council and the 49 municipalities in the region, from 1 January 2012 the county council is the sole owner. The fleet consists of approximately 1700 vehicles.
The whole of Göteborg's public transport network is equipped with sensors which track the location of every bus or tram at any given time. The system allows to estimate when a tram or bus will be leaving from the next stop in real time. This information is displayed in bus and tram shelters, and indicating any delays affecting the next bus or tram.
