Abstract

This paper presents a definition of boundedly rational confidence level (BRCL) which is the probability that a trip arrives within the shortest travel time budget plus the acceptable travel time difference (i.e. boundedly rational threshold). Using the method of data fitting, boundedly rational threshold is estimated. Then, a reliability-based boundedly rational user equilibrium (R-BRUE) model that explicitly considers both travel time reliability and travelers' bounded rationality in the route choice decision process is proposed. This new model hypothesizes that for each origin-destination (O-D) pair no traveler can improve his/her BRCL by unilaterally changing routes. A route-based quasi-method of a successive average algorithm is developed to solve the R-BRUE model. Numerical examples illustrate the essential ideas of the proposed model and the applicability of the proposed solution algorithm.
