L'acceptabilité des changements tarifaires dans le secteur des transports : comment concilier efficacité et équité ?

One works out an analytical framework of the acceptability of pricing changes in the transport sector. This framework is built on the confrontation of the economic efficiency, territorial equity, horizontal equity, and vertical equity dimensions. This analytical framework is then applied to some ongoing urban and suburban road toll schemes in various countries. The analysis shows that these efficiency and equity dimensions combine themselves, by most often reinforcing the ones the others in their negative or positive aspects. This analysis also shows that these various dimensions of equity cannot be ignored on pain of failure. Moreover, it enables us to identify the ways according to which the acceptability of urban road pricing could be improved, if not guaranteed. Classification JEL : R48, D61, D63.<np pagenum="540"/>
