Traffic forecasts provide essential input for the appraisal of transport investment projects. However, according to recent empirical evidence, long-term predictions are subject to high levels of uncertainty. This paper quantifies uncertainty in traffic forecasts for the tolled motorway network...

The objective of this paper is to analyse to what extent the use of cross-section data will distort the estimated elasticities for car ownership demand when the observed variables do not correspond to a state equilibrium for some individuals in the sample. Our proposal consists of approximating...

This paper analyses the factors determining the growth in car ownership in Spain over the last two decades. A discrete choice model is estimated at three points in time: 1980, 1990 and 2000. The paper compares the two alternative decision mechanisms used for modelling car ownership:...

The objective of this paper is to estimate the impact of residential job accessibility on female employment probability in the metropolitan areas of Barcelona and Madrid. Following a 'spatial mismatch' framework, a female employment probability equation is estimated which includes variables...

In this article we provide a comparison of different formulations for hedonic regression analysis in order to construct a quality adjusted price index for the Spanish car market over the period 1981 to 2005. Specifically, we address the issue of instability of coefficients over time, and propose...

This paper analyses the elasticities of demand in tolled motorways in Spain with respect to the main variables influencing it. The demand equation is estimated using a panel data set where the cross-section observations correspond to the different Spanish tolled motorways sections, and the...
