Abstract: This research investigated the integration of bus lines with on-demand passenger transportation mixed with parcel delivery services for last-mile transportation. A mixed integer programming formulation is proposed for the optimisation problem of finding routes for the delivery vehicles, synchronising them with the bus lines, so that passengers and parcels use both modes in their trips. To validate the model, we used randomly generated instances based on a rural community and solved them using a commercial solver. We compare the performance of such a system against non and partially integrated scenarios and show that significant savings in drive time can be achieved, even when prioritising the passengers' perspectives. We also present a method to aid a decision-maker in visualising the trade-off of this prioritisation for the service operator. These findings suggest that the proposed approach might be particularly effective in rural areas, but these conclusions are highly dependent on the instances.
