Each of the lines were divided in two fare zones. In 1954, the concession for operation of buses in Cannes was given to Société des Transports Urbains de Cannes by the Syndicat Intercommunal des Transports Publics for twenty years. Several lines were created during the 1960s, linking Cannes to la Californie, Cannes and le Cannet via République and Cannes to l'Aubarède. Lines were divided into four fare zones. In 1968, severe strikes forced the company to reduce its staff presence on buses to one.
The STUC's concession was extended by ten years in 1974 thanks to a grant to the STIP. The company adopted a new ticketing system, using magnetic strip cards. Lines were grouped into two global fare zones in replacement of the four per line. Service was increased with the purchase of more rolling stock. Within two years, stock and staff numbers doubled.
In 1978, the STUC purchased a diesel multiple unitX 94630 for use on the Cannes-Ranguin railway line. Service was eleven minutes in length and bus ticketing used.
The concession was once more extended, for five years, in 1984, with further bus purchases and the repainting of the X 94630 into the line's colours. rail services ended in 1995 due to loss of revenue. On 5 November 1996, CGFTE Cannes signed a contract delegating services. In 2004, Bus Azur introduced double-decker buses on its line 8 quai Laubeuf-La Croisette-Palm Beach.
