In this paper the social costs of land use claims for transport infrastructure are investigated for The Netherlands. This is a complement to the study on 'Efficient pricing of traffic: estimation of the social costs of the use of transport modes" carried out in The Netherlands by CE (1999). In the present study we pay attention to the acquisition costs of land for infrastructure, the indirect costs of land use caused by infrastructure and the costs of infrastructure as barriers in - and the fragmentation of - the landscape. The paper gives an overview of the problems associated with measuring the land related costs of transport infrastructure. Estimates are given of the land use claims in m2) for various types of transport infrastructure. In addition some of the land related cost categories are estimated. These costs are allocated to the various transport modes (cars and trucks of various types, barges, rail and aircraft).
