Wang, S. (author), Zhu, Xiaoning (author), Shang, Pan (author), Lin, X. (author), Yang, Liya (author), Tavasszy, Lorant (author)The considerable increase in parcel deliveries has negatively impacted the accessibility and livability of cities. One solution strategy is to decouple short-distance from long-distance shipping so that last-mile transport can be performed with low-footprint vehicles. Such solutions are referred to in the literature as multi-echelon...journal article 2024

Leffler, David (author), Burghout, Wilco (author), Cats, O. (author), Jenelius, Erik (author)Over the past decade, there has been a surge of interest in the application of agent-based simulation models to evaluate flexible transit solutions characterized by different degrees of short-term flexibility in routing and scheduling. A central modelling decision in the development is how one chooses to represent the mode- and route-choices...journal article 2024

Brederode, L.J.N. (author)Strategic traffic assignment (TA) models assess long-term effects of policies on route choices of travelers. To meet stability requirements, current strategic TA models lack modelling of queues. This thesis develops two TA models that include queue modelling whilst satisfying stability requirements along with a method to fuse observed link flows...doctoral thesis 2023
