Road Transportation and Freight Services

Road transportation and freight services form the backbone of modern supply chains, carrying over three-quarters of inland goods by tonne-kilometre in many regions. These services encompass long-haul trucking on motorways, regional distribution via articulated vehicles and urban logistics using vans, light-goods vehicles and specialised carriers. Efficiency in this sector depends on vehicle utilisation, routing, loading techniques and infrastructure performance. Recent decades have seen the integration of digital tools—such as GPS tracking, real-time traffic management and data-driven demand forecasting—to optimise asset deployment, reduce empty runs and enhance delivery punctuality. At the same time, environmental imperatives have driven efforts to decarbonise operations through cleaner propulsion technologies, aerodynamic improvements, electrification and novel delivery concepts. Urban freight challenges include curb-side loading, congestion and emissions hotspots, prompting innovations in micro-fulfilment, cargo bikes and shared delivery platforms. The interplay of policy, infrastructure, technology and commercial systems continues to reshape the sector, aiming for more resilient, cost-effective and sustainable road freight networks.

Research from Nature Portfolio

Studies have quantified the system-wide impact of coordinated heavy-vehicle platoons, demonstrating that close-formation truck convoys can cut fuel use by reducing aerodynamic drag but may accelerate road wear. A comprehensive analysis at network scale showed net greenhouse-gas savings of around 5% when maintenance-related emissions are accounted for, highlighting trade-offs between vehicle efficiency and infrastructure durability. Investigations into unmanned aerial vehicles for parcel delivery have compared the energy and emissions of small drones with conventional trucks. Although drones require extra warehousing energy and travel longer distances per package, their per-package-kilometre emissions often remain lower, suggesting that carefully planned drone networks can contribute to freight decarbonisation. In urban loading contexts, trials of intelligent parking systems delivering real-time curb availability to drivers cut cruising time by nearly 28% and distance by over 12%, indicating that shared information can significantly improve urban delivery efficiency and reduce local emissions.

Technical terms

Truck platooning: Cooperative driving formation in which two or more heavy vehicles travel in close succession under automated speed-and-gap control to reduce aerodynamic drag.

Life-cycle greenhouse-gas emissions: Total emissions attributable to a delivery system, including production, operation and infrastructure maintenance phases.

GPS trajectory: A time-stamped sequence of vehicle positions used to infer trips, stops and routes for freight demand modelling.

Origin–destination flow: The aggregated quantity of freight vehicles moving from a specific starting zone to a destination zone within a transport network.

Curb availability information: Real-time data on on-street loading bay occupancy which can be communicated to drivers to optimise parking and reduce cruising time.
