The Carte orange was launched in 1975, at a time when fare collection for public transit in Paris and the surrounding region was very complicated — in fact, someone wanting to traverse Paris at the time might have had to buy five separate tickets. There had been several attempts to simplify ticketing in the Parisian public transport system in the past. Notably in 1968 a ticket valid for use in the bus and metro, the "Ticket ivoire commun" (common ivory ticket) was introduced and three years later a ticket valid in the SNCF, buses, metro and "cars de banlieue" was launched. Nevertheless, the Carte orange was novel in that it was the first ticket that gave the passenger unlimited access to all of the region's public transports for a flat rate, and during a specific period of time. a one-use ticket can be used in any form of the Paris public transit system.
