Summary
This paper addresses the challenge of deploying effective information-based network control strategies in congested vehicular traffic systems by integrating realistic driver behavior models. Traditional Dynamic Traffic Assignment (DTA) approaches often rely on rigid assumptions regarding driver compliance and pre-specified behavioral classes, which can lead to incorrect predictions of system states and potentially deteriorate performance. The authors propose a "behavior-consistent" methodology that explicitly factors in the controller’s estimation of driver response behavior when determining control strategies. This approach aims to bridge the gap between theoretical DTA models and practical deployment constraints, such as limited data availability, by ensuring that information strategies are consistent with both controller objectives and likely driver reactions. The study employs a fuzzy control-based optimization framework to solve a fixed-point problem where information strategies and estimated driver responses are interdependent. The controller seeks to minimize the difference between System Optimal (SO) route proportions and the actual proportions of drivers choosing those routes. To achieve this, the authors define four driver information classes based on subscription types: prescriptive information only, descriptive linguistic information only, both, or no information. The methodology utilizes a hybrid multinomial logit model combined with Monte Carlo simulation to estimate individual driver route choices based on route attributes, prescriptive recommendations, and linguistic messages (e.g., "heavy traffic ahead"). The problem is formulated as a non-linear mixed integer model that simultaneously determines prescriptive and descriptive information strategies for "controllable routes"—routes that are both desired by the controller and preferred by drivers. Experiments were conducted to evaluate the effectiveness of the proposed behavior-consistent methodology compared to traditional DTA approaches. The results demonstrate that incorporating behavior consistency is critical for reliable system performance estimation and control. Strategies derived without accounting for realistic driver response behavior can lead to suboptimal outcomes. Specifically, the behavior-consistent approach generates more meaningful strategies by adjusting the proportions of drivers recommended for specific routes to account for innate behavioral tendencies and situational factors, rather than assuming rigid compliance. This allows the controller to approach SO proportions more effectively by providing personalized or class-specific information that aligns with driver expectations. The significance of this work lies in its contribution to the development of realistic, deployable traffic control paradigms. By recognizing the limitations of pre-specified behavior models and the practical constraints of data availability, the proposed method offers a robust framework for real-time traffic routing. It highlights that information provision must be tailored to driver response tendencies to enhance system performance. The findings suggest that future traffic management systems should prioritize behavior-consistent strategies to avoid the pitfalls of traditional models, thereby improving the reliability and effectiveness of information-based network controls in complex, congested environments.
