Stochastic user equilibrium model with implicit travel time budget constraint

TE Smith, CC Hsu, YL Hsu - Transportation research record, 2008 - journals.sagepub.com
Although time constraints on travel behavior have been widely recognized, little effort has
been made to incorporate such constraints into the traditional stochastic user equilibrium
(SUE) framework. The major objective of this research is to fill this gap by incorporating
travel time constraints into the SUE model by means of a nonlinear perceived travel time
function. This modified model, designated the travel time budget model, focuses primarily on
discretionary travel behavior (such as shopping trips) and hence also allows the possibility …
