Les réseaux de transport à grande vitesse en France : construction et apports d'un système d'information géo-historique
The originality of this Historical Geographic Information System (SIGH) is that it is focuses on various transport networks (road and railway) at several temporal scale (from 1975 to 2010). The corresponding spatial network offers the possibility to generate spatial and temporal matrices across France, at different dates. These possibilities open important spatial analysis perspectives. They allow for example to assess the effect of investments in high-speed transport supply on the durations of intercity trips, also multiple opportunity in the field of Regional Science and Complex Systems analysis.
Comment réduire les émissions de CO2 du transport de fret en France ? Évaluation socio-économique de trois politiques publiques
France must implement voluntarist policies in order to reduce CO2 emissions, which raises questions regarding the effectiveness of competing options and their costs, for both public finances and society. This paper estimates abatement costs of one ton of CO2 from three scenarios aimed at softening the environmental impacts of freight moved by trucks. Hybrid trucks may generate large CO2 savings (5.7 Mt/year in 2030), at a moderate discounted abatement cost (88 €/t). The option based on natural gas for vehicles leads to a similar abatement cost and to lower environmental gains (3.2 Mt/year in 2030). Whilst inducing small CO2 savings (0.2 Mt/year in 2030), megatrucks present a negative discou…
