Public Planning of freight transport in logistically complicated small cities
On Friday 30 August 2024 Cosku Can Orhan will hold a trial lecture on a prescribed topic and defend his thesis for the PhD degree at NHH.
Public authorities may intervene in the operations of freight carriers to mitigate their impact on urban environments through regulations or incentives that promote sustainable practices. However, authorities often lack the knowledge required to analyse carriers' operations and implement corresponding measures.
This challenge is particularly pressing for authorities in small European cities, where they must navigate logistically complex landscapes characterized by medieval structures, narrow roads, and limited parking spaces.
Cosku Can Orhan’s thesis originates from this context and aims to bridge the knowledge gap between public planning and freight transport in small, logistically complicated cities.
In particular, the first paper proposes a routing-based policy guidance framework to examine the value of consolidation from the perspective of authorities. By analysing various market structures characterized by different numbers and sizes of carriers in Bergen, which define different degrees of consolidation, the paper concludes that implementing a delivery network where small carriers do not deliver directly to end customers would greatly enhance city livability.
The second paper looks into a regulatory measure designed by authorities in Bergen to prevent through traffic in the city centre. The paper analyses how the zoning decision would affect freight transport and quantifies its impact on the urban environment.
The findings indicate that alongside the anticipated increase in total driving for freight deliveries throughout the city, there would also be a rise in traffic within the city centre itself, which may not have been intended or expected.
The third paper focuses on the integration of freight deliveries into the concept of an X-minute city by adopting a dense, carrier-agnostic parcel locker network as a relevant business model for e-commerce shipments. The findings suggest that eliminating carriers' failed deliveries would bring substantial benefits to the city, with a significant portion of these benefits arising from small carriers.
The sustainable practices advocated in public planning of freight transport have led to exploring how to integrate such practices into the route planning of carriers. Accordingly, the last paper addresses how to re-plan the sequence of customer visits once a vehicle returns to the depot in the VRPs with stochastic demand.
The problem exhibits a multistage structure, and the paper discusses how to formulate such problems (and under which conditions) by repeatedly reusing a single static representation of uncertainty.
