Choice Sets and Smart Card Data In Public Transport Route Choice Models: Generated vs. Empirical Sets

Abstract: This study evaluates path sets generation for route choice models in multimodal public transportation networks, using both conventional (network algorithms) and empirical (smart card data driven) methods. While the empirical approach can present limitations with a short observation period, it improves substantially with more data, offering a computational efficiency advantage over conventional methods. In such approach, while incorporating real-world delays increased travel time variability, it still aligned with planned travel times, and relaxing access/egress assumptions further enhanced coverage. Work is undergoing on the evaluation of the impact of different choice sets in bias and efficiency of route choice parameter estimates.
