Abstract (EN): In this paper, we examine the accessibility benefits from some land-use policy strategies for the Netherlands that anticipate to a greater or lesser degree on expected climate changes. A disaggregate logsum accessibility measure is used as appraisal method to compute changes in consumer surplus using the Dutch national land-use/transport interaction model TIGRIS XL. This paper shows that the logsum accessibility measure provides an elegant and convenient solution to measure the full accessibility benefits from land-use and/or transport policies, when a travel demand model (using discrete choice models) is available that already produces logsums. The logsum measure accounts for both changes in (generalised) transport costs and changes in destination utility, and is thus capable of providing the accessibility benefits from changes in the distribution of activities, due to transport or land-use policies. The case study shows that logsum accessibility benefits from land-use policy strategies can be quite large compared to investment programmes for road and public transport infrastructure. The accessibility impacts from the land-use scenarios are largely due to changes in trip production and destination utility, which are not measured in the standard rule-of-half benefit measure. The logsum benefit measure thus goes beyond the current practice of rule-of-half benefit calculations. Ignoring accessibility benefits from land-use changes resulting from transport investments may lead to serious biases. Moreover, the accessibility benefits from land-use or integrated land-use/transport scenarios computed by the standard rule-of-half measure may be strongly under- or overestimated, and have the wrong sign.
