New high-speed rail transport infrastructures produce profound time-space changes that make new activities possible. Our aim is to measure the impact of such changes on potential business or leisure travel between cities. We develop a contact potential indicator (Törnqvist, 1970) that measures the possibility of making a trip to a distant location within the desirable time-space prism. The indicator is developed in the context of the high-speed rail line between Tours and Bordeaux. The results demonstrate the possibility of contact from a series of key cities affected by new high-speed rail infrastructure, both before and after project completion. Our analysis shows that Bordeaux benefits greatly from the extension of the rail line: the preferred method of contact to Paris will switch to rail from the current air preference, and several cities that cannot be reached in the current pre-project conditions will become “contactable”. Other cities that benefit are Angoulême, Tours and Poitiers.... view less

Les nouvelles infrastructures de transport ferroviaire provoquent de profondes transformations de l’espace-temps qui rendent de nouvelles activités possibles. Notre but est de mesurer les impacts de telles transformations sur le potentiel de déplacement pour motif affaires ou tourisme entre villes. Nous développons l’indicateur du potentiel de contact (Törnqvist, 1970) qui mesure la possibilité d’effectuer un déplacement vers un lieu distant dans les contraintes du prisme d’espace-temps de la time geography. L’indicateur est mis en œuvre dans le contexte de l’ouverture de la ligne ferroviaire à grande vitesse entre Tours et Bordeaux. Les résultats démontrent la possibilité de contact entre un ensemble de villes clés affectées par la nouvelle infrastructure de transport rapide, avant et après son ouverture. Notre analyse montre que Bordeaux bénéficie grandement de l’extension de la ligne : le mode le plus favorable pour réaliser le potentiel de contact avec Paris bascule de l’aérien au ferroviaire, et plusieurs villes qui ne pouvaient pas être rejointes dans les conditions précédant la réalisation du projet ferroviaire, deviennent « contactables ». Les autres villes bénéficiaires sont Angoulême, Tours et Poitiers.... view less
