In order to study the different travel behaviours of users equipped with advanced traveler information systems (ATIS) and users unequipped with ATIS under uncertainties conditions in both demand and supply sides of a road network due to adverse weather conditions with different rainfall intensities, a path travel time reliability-based traffic assignment model under endogenous equilibrated market penetration and compliance rate of ATIS was established. Those equipped users may not always comply with the advice provided by ATIS. Therefore users are divided into three classes: users with ATIS and in compliance with ATIS advice, users with ATIS but without compliance with ATIS advice, and users without ATIS. Users will consider uncertainty of the path travel time, weather conditions, and ATIS advice in their path choice decisions. Furthermore, the model also considers users' perception errors using a Logit-based stochastic user equilibrium framework. The proposed model is formulated as an equivalent variational inequality problem in terms of path flows. Numerical examples illustrate the efficiency of the proposed model and solution algorithm.

Users may not always comply with the advice provided by advanced traveler information systems (ATIS). Therefore users are divided into three classes: users with ATIS and in compliance with ATIS advice, users with ATIS but without compliance with ATIS advice, and users without ATIS. Besides, users are further divided into several groups according to their value of time (VOT). The stochastic system optimum congestion pricing under endogenous equilibrated market penetration and compliance rate of ATIS in a network with recurrent congestion was studied. A stochastic system optimum congestion pricing model with multiple user classes under endogenous equilibrated market penetration and compliance rate of ATIS was established. Numerical examples indicate that the improvement of quality of traffic information provided by ATIS can help to reduce the total network congestion charge; though both the rich and the poor are equipped with ATIS, they have different route choice behaviors, the rich have higher market penetration and compliance rate of ATIS compared to the poor; the quality of information provided by ATIS affects both market penetration and compliance rate of ATIS.
