While real-time travel information can aid travelers to make informed decisions, it may increase the cognitive load in information perception and the complexity in decision-making process, especially when the information is from multiple sources. Under this circumstance, human factors-related aspects in information perception and the consequent psychological effects of the information play significant roles in traveler route choice decision-making. This study proposes a hybrid route choice model under the presence of real-time travel information, in which latent variables are employed to represent the psychological effects of information provision. Three dimensions of psychological effects – cognitive burden, cognitive decisiveness, and emotional relief – are assumed as latent psychological constructs in the proposed model. Data on traveler behavior and information perception are obtained through interactive driving simulator-based experiments. Estimation results will verify that the inclusion of the latent variables enhances the understanding of route choice decision-making under information provision.
