Summary

This study addresses the limitations of current Advanced Traveler Information Systems (ATIS) by proposing an integrated analytical framework that incorporates human factors and psychological processes into the evaluation of real-time traffic routing. Traditional assessments of ATIS benefits focus primarily on physical metrics, such as travel time savings and network congestion reduction. However, the increasing availability of information from multiple heterogeneous sources creates cognitive stress and perception challenges for drivers. This research aims to systematically analyze the comprehensive benefits of real-time information, including qualitative and psychological attributes that influence driver behavior, which have been largely overlooked in existing literature. The methodology involves developing a conceptual model of the driver’s psychological process, divided into three stages: perception of information, psychological effects during the trip, and psychological benefits (satisfaction) after the trip. The authors define three specific psychological effects: cognitive burden (stress from processing excessive information), cognitive decisiveness (confidence derived from the sufficiency and consistency of information), and emotional burden (feelings of security or stress based on the favorableness of the information). To validate this framework, the study utilizes data from interactive driving simulator experiments conducted in a realistic network of Indianapolis, Indiana. These experiments integrate microscopic traffic simulation with dynamic traffic assignment to provide varying background traffic demands and diverse information scenarios. The design captures both behavioral responses and subjective psychological states through intermediate and post-trip surveys, overcoming limitations of previous static or simplified simulator studies. The findings establish a statistical modeling structure using Multiple Indicators Multiple Causes (MIMIC) models to quantify these psychological effects. The research demonstrates that driver satisfaction is a latent variable influenced not only by experienced travel time but also by the psychological effects of information provision. Specifically, the amount, source, and content of information impact driver perception through dimensions of ease of comprehension, consistency, sufficiency, and favorableness. The study confirms that psychological states, such as reassurance or cognitive stress, significantly contribute to the overall evaluation of the travel experience, independent of physical travel time outcomes. The significance of this work lies in its expansion of the value proposition for ATIS investments. By including psychological benefits, such as improved mental states and reduced uncertainty, the framework provides a more holistic justification for infrastructure investments from the perspective of travel experience quality. This approach aids public and private information providers in designing more effective real-time travel information systems that account for users’ cognitive limitations and emotional responses, thereby enhancing the overall effectiveness and acceptance of predictive real-time traffic routing technologies.

Key finding

Driver satisfaction with real-time travel information is determined by both experienced travel time and latent psychological effects, specifically cognitive burden, cognitive decisiveness, and emotional burden.
