Alors même que la relation vertueuse entre infrastructures de transport et développement reste l’un des mythes les plus solidement ancrés dans l’esprit des acteurs, publics comme privés, les travaux empiriques relatifs aux effets des dessertes ferroviaires à grande vitesse aboutissent...

In Paris, an old bus line on the Maréchaux Boulevards has been replaced by a modern tramway. Simultaneously, the road-space has been narrowed by about a third. A survey of 1000 users of the tramway shows that the tramway hardly generated any shift from private cars towards public transit mode....

On the southern part of the Parisian Maréchaux' boulevards, the old bus line Petite Ceinture has been replaced by a modern tramway (T3). Simultaneously, the road-space has been narrowed by about a third. A survey conducted on 1,000 users of the T3 shows that the tramway hardly generated any...

Cet article se propose de mettre en perspective les théories "traditionnelles" de la croissance régionale avec la théorie de l'entrepreneur. La revue de littérature que nous menons montre que, si la figure de l'entrepreneur n'est que très partiellement mobilisée dans les explications de la...

This research focus on the congestion cost of the Parisian ring-road. We mobilize a speed-density relation which enables us to differentiate the costs of the road's use and its congestion according to speed-classes of 5 km/h. We lead this work at three analytical scales thanks to a large...

This research aims at appraising the determinants of entrepreneurship dynamism in the French administrative regions over the period 1993-2004. First, we highlight how the regional territory may be considered under a double dimension in order to explain the differentials between the regional...

The aim of this article was to assess specific problems concerning traffic congestion access to the city of Paris. First, we attempted to evaluate the evolution of the congestion cost for the Paris Ring-Road (PRR), the major urban highway surrounding the French capital, during the period from...

Sur le quart des boulevards des Maréchaux, le bus a été remplacé par un tramway et simultanément les voies routières ont été rétrécies. Une enquête auprès de 1000 usagers montre que le tramway n'a engendré presque aucun transfert modal de la voiture vers les TC. Mais il a engendré...

Qualitative aspects of transport experiences are increasingly discussed as factors influencing the choice between individualized and public transport. In this article we investigate, both analytically and empirically, the impact travel comfort has on the utility of subway users as well as the...

The paper argues that congestion in public transportation is alike the much more studied road congestion. It sets out to produce, on the case of the Paris subway, a congestion cost curve linking the willingness to pay for non-congested travel to actual congestion levels. Congestion costs appear...
