— Urban parcel delivery has emerged as a high growth
market, and the resulting delivery traffic can pose great
challenges in dense urban areas. There is growing interest in
supplanting the conventional model of a dedicated delivery
person operating a van to alternatives featuring new classes of
vehicles such as drones, autonomous ground vehicles, cargo bikes
and non-motorized vehicles. This work proposes combined
delivery strategies using trucks, cargo bikes and drones. We
develop and compare multi-modal delivery strategies with
various mode combinations. We work on zone-based multi-modal
delivery strategies in multi-echelon networks. Then, we evaluate
the benefit of multi-modal delivery in both uncongested and
congested transportation networks. Results show that delivery
models with multiple vehicles modes in both single- and multiechelon networks are more efficient in terms of total delivery cost
than truck only scenario. The multi- modal delivery strategies in
two- echelon networks outperform other strategies in extremely
congested situations. We suggest taking advantage of synergistic
operation among emerging vehicle types, especially drones for
more efficient parcel delivery.
