The paper deals with the interaction between freight flows, land use, and economy of a suburban area. In urban freight distribution, the process of freight acquisition of commercial establishments represents a crucial element. Therefore, it is necessary to plan city logistics in order to reduce the negative externalities generated by freight transport without depressing the economic and social vitality. In order to estimate and evaluate the performance and impacts generated by urban freight distribution, Transport System Models (TSMs) play an important role in reproducing and forecasting the process of distribution of final products to retailers and consumers. In recent years, Information and Communication Technologies (ICTs) have made new sources of data in great amounts available at lower costs than data provided from traditional surveys. Among the different data sources, Floating Car Data (FCD), obtained through GPS trackers installed on board the vehicles, offer partial insights into the examined process with lower cost and provide continuous information in space and time. In order to obtain reliable results, it is necessary to combine TSMs and ICTs as observed data could feed Transport System Models and could allow their calibration and therefore their application in real cases. In the above context, the paper deals with TSMs related to estimating urban freight demand flows. The work carried out concerns the specification-calibration-validation of a freight zonal acquisition model by means of FCD related to interzonal trips of commercial vehicles inside the Locride area (Reggio Calabria, Italy). The obtained models, estimated from FCD, could support the a priori evaluation of city logistics measures. The results are more important considering that they are obtained in an area with a lack of transport monitoring technologies. They could be adopted in other similar areas and confirm that adequate planning of city logistics determines advantages for environmental, social, and economic sustainability.

“…Each of these components can be linked to one or more stakeholders viz Receivers (generators of demand for goods and, therefore for transport on the demand side), Shippers (send goods to fulfil this demand), LSPs (undertake logistics operations and actual deliveries as a direct result of the interaction between Receivers and Shippers). Contextual movements are regulated by Local Authorities, and the physical environment where all this takes place, is inhabited by Citizens (Kin et al, 2017;Guerlain et al, 2018;City Vitality and Sustainability, 2020;Diana et al, 2020).…”

The construction industry’s inherent fragmentation fuels Construction Supply Chain (CSC) complexity. Logistics form an essential part of the CSC in terms of costs and project management. In turn, transportation accounts for more than half the logistics costs due to construction materials being low-cost/high-volume, and most other logistics processes being business processes and not physical ones. Construction transport is almost entirely road bound, one of the least sustainable modes with externalities far out of proportion to its numbers. Ergo, its optimisation presents substantial greening (de-carbonisation) opportunity, with potentially far-reaching sustainability impacts. The ASI (Avoid-Shift-Improve) concept considers activity, modal structure, and energy intensity/efficiency as transport carbon components, providing a fundamental optimisation framework. 93% of New Zealand’s freight (a third of it construction related) is road bound, with 99% fossil-fuel (diesel) dependence. Government adoption of ASI elements viz Supply Chain (SC) efficiency, transport optimisation, data/information sharing, and collaboration for transport decarbonisation aligns with Industry 5.0, but seeks further research for concrete implementation pathways. This paper aims to bridge the gap by proposing a research framework for greening of construction transport as a sustainability enabler for New Zealand.

Despite their importance, relatively little attention has been paid to vehicle routing problems with asymmetric costs (ACVRPs), or their benchmark instances. Taking advantage of recent advances in map application programming interfaces (APIs) and shared spatial data, this paper proposes new realistic sets of ACVRP benchmark instances. The spatial data of urban distribution centers, postal hubs, large shopping malls, residential complexes, restaurant businesses and convenience stores are used. To create distance and time matrices, the T map API, one of the most frequently used real time path analysis and distance measurement tools in Korea, is used. This paper also analyzes some important issues prevailing in urban transportation environments. These include the challenges of accounting for the frequency and distance in which air travel differs from reality when measuring closeness, the differences in distance and time for outgoing and return trips, and the rough conversion ratios from air distance to road distance and to road time. This paper contributes to the research community by providing more realistic ACVRP benchmark instances that reflect urban transportation environments. In addition, the cost matrix analyses provide insights into the behaviors of urban road networks.
