Abstract

In this paper, we study the level of service reliability (LOS reliability) problem in a transportation environment with advanced traveler information systems (ATIS). Two classes of drivers, equipped with and unequipped with ATIS respectively, exist in the system and make their route choices in a logit-based stochastic manner with different travel time perception errors. Treating the capacity of each link and each OD pair as discrete random variables, we establish an approximation algorithm to estimate the road network LOS reliability based on the road network most probable states generation method. Finally, a numerical example of a small road network is presented to validate the proposed model and algorithm.
