Travel Time Budgets: Facing the paradoxical management of the "scarcest good". - The underlying increase of income changes our daily time use. According to the fact that the daily time budget is strictly stable, time becomes, in relative terms, the scarcest resource. Facing this growing feeling of time scarcity, faster transport modes are developed to help us to save time. Nevertheless, everything happens as if, despite the speed increase, the scarcity of time is growing. To enlighten this paradox, travel time budgets of industrialised cities are analysed. First the Zahavi's conjecture of the travel time budget (TTB) stability is reviewed. With the reinvestment, in new trips, of travel time savings due to higher speed, we obtain a space and time urban sprawl. Such a mechanism is observed in North American and Oceanic towns. An "extensive urban model" can be characterised by increasing travel distances and TTB. In opposition, Asian and European cities form the "intensive urban model", with stable TTB. What is the signification of this European specificity? Is Europe simply lagging behind the North-American "model". Or is it a different way of managing the scarcity of time?
