| Abstract | dc.description.abstract | The traditional formulation of logit models applied to transport demand assumes a compensatory
(indirect) utility function in which the consumers’ strategy assumes a tradeoff
between attributes. Several authors have criticized this approach because it fails to recognize
attribute thresholds in consumer behavior, or a more generic domain where such a
compensatory strategy is contained. In this paper, a mixed strategy is proposed, which
combines the compensatory strategy valid in the interior of the choice domain with cutoff
factors that restrain choices to the domain edge. The proposed model combines the multinomial
logit model with a binomial logit factor that represents soft cutoffs. This approach
extends previous contributions in several ways and allows multiple dimensions for cutoff
factors. In addition to considering individual behavior, it introduces system constraints
such as capacity and inter-agent interactions (choice externalities). This extension yields
a non-linear problem, which is solved by analyzing the fixed point problem. Additionally,
a set of evaluation tools, a social utility of the constrained problem, and a measure of the
shadow price of each constraint, are proposed. | en_US |
