<p>This study introduces the Agent-Based Travel Scheduler (ABTS) model, designed to predict individual travel schedules by decomposing GPS-based aggregated Origin–Destination data according to demographic features and trip purposes. ABTS improves upon traditional models by generating detailed individual travel schedules based on agent-based modeling within an activity-based framework. The model’s accuracy is refined through robust validation by calibrating key parameters that influence individual travel patterns in both spatial and temporal dimensions. Applied to Milwaukee, Wisconsin, USA, the model demonstrated 83% accuracy in estimating travel patterns, including the movements of different age groups across weekdays and weekends, by time of day, trip purpose and destination.

ABTS offers advantages in computational efficiency, flexibility in parameter adjustment and adaptability to various urban scenarios, making it a valuable tool for policy analysis and urban planning.</p>

摘要

This study introduces the Agent-Based Travel Scheduler (ABTS) model, designed to predict individual travel schedules by decomposing GPS-based aggregated Origin–Destination data according to demographic features and trip purposes. ABTS improves upon traditional models by generating detailed individual travel schedules based on agent-based modeling within an activity-based framework. The model’s accuracy is refined through robust validation by calibrating key parameters that influence individual travel patterns in both spatial and temporal dimensions. Applied to Milwaukee, Wisconsin, USA, the model demonstrated 83% accuracy in estimating travel patterns, including the movements of different age groups across weekdays and weekends, by time of day, trip purpose and destination. However, it showed reduced performance in densely populated downtown areas and locations where special events that attract large crowds occurred, highlighting opportunities for further refinement. ABTS offers advantages in computational efficiency, flexibility in parameter adjustment and adaptability to various urban scenarios, making it a valuable tool for policy analysis and urban planning.
