Assessing Economic Impacts of Large-Scale Transport Infrastructure Projects: Case of Lyon-Turin Corridor

Abstract

Assessment of large-scale transport infrastructure projects by a classical four-stage transport network model is meant to capture only the direct benefits of transport policies, while the additional indirect economic effects in nontransport markets would be partially neglected. The intent of this paper is to apply an integrated economy-transport-environment assessment model focusing on the assessment of economic impacts of national or supranational transport policies to the question of the size of indirect economic impacts of a single large-scale project. Such a model makes it possible to consider the interaction between transport and the economy as well as between the economy and transport, closing the transport-economy feedback loop. For this purpose, the European assessment of transport strategies (ASTRA) model is refined to model the implementation of the planned high-speed railway link on the Lyon-Turin corridor. This line forms part of the Trans-European Transport Networks. The estimated cost of the...
