Resumen:
Several international studies have analyzed the acceptability of road pricing schemes by
means of an attitude survey in combination with the results of a stated choice experiment
using both a descriptive analysis and a discrete-choice model with binary choice ("accept"
or "not accept" the toll). However, the use of hybrid discrete choice models constitutes an
innovative alternative for integrating subjective attitudes and perceptions deriving from
the survey of attitudes with the more objective variables from the stated choice experiment.
This paper analyzes the results of applying these models to measure the acceptability
of interurban road pricing among different groups of stakeholders (road freight and
passenger operators, highway concessionaires, and associations of private car users) with
qualitatively significant opinions on road pricing measures. Our results show that hybrid
models are better suited to explaining the acceptability of a road pricing scheme by different
groups of stakeholders than a separate analysis of the survey of attitudes and a discrete-choice
model applied on a stated choice experiment. A particular finding was that
the strong psycho-social latent variable...
