The Carte orange was also intended to boost the use of public transit, then in rapid decline, due to increasing use of cars. In fact, at the end of the 1960s, the transport ministry was actually considering abolishing bus service in Paris. However, within a year of the Carte's introduction, bus usage went up 40%, and more generally, it has been estimated that during the first ten years of its existence, the Carte led to an increase of 20% in the use of Parisian public transport.
