Dijon Métropole has been rolling out a “global mobility” plan since 2017, aiming to facilitate travel within the metropolitan area while encouraging users to choose low-impact and shared means of transport rather than private cars: trams, buses, bikes or walking.

The line, which is 14.5 km long and serves 26 stations, is expected to carry between 10 and 11 million passengers every year and takes 42 minutes to connect Tarup, a neighbourhood in the north of the city, to Hjallese in southern suburb of Odense. It will run through the downtown area, serving the main points of interest in the centre including the central station, the hospital, and Odense University. Keolis has recruited 80 local staff for this contract, including 52 drivers.
