Under-utilisation of road freight vehicle capacity: A case for eco-efficiency through collaboration

The road haulage sector experiences a considerable amount of inefficiency, characterised by sub-optimal utilisation of an individual vehicle’s cubic load fill and weight hauling capacity. This study firstly aims to understand why – despite its evident economic and environmental cost – this phenomenon has existed over the years. Next, an overview of initiatives and opportunities for improving freight vehicle capacity utilisation will be given. This paper by no means attempts to suggest that part-loaded or empty trucking can be fully eliminated. What is argued however is that there is theoretical scope for reducing the socio-environmental externalities of these activities while sustaining – if not increasing – the benefits that road haulage offers to the economy. Alongside direct mitigation of energy efficiency (by vehicle technology and/or modal shifts), maximizing existing vehicle capacity utilization must also form an integral part of efforts to green modern road freight logistics.It is suggested that horizontal collaboration and multi-actor co-loading of freight vehicles holds the greatest potential for improving vehicle fill rates. This requires little capital investment and would mean that the same degree of utility is delivered with fewer individual vehicles on the road. However, it is also argued that a collaborative road freight model may come in conflict with modern customer demands and production patterns, which typically involve rapid just-in-time deliveries of ever smaller consignments. Subsequently the widespread outsourcing of road freight operations to external third-party operators has not resulted in pronounced gains in vehicle capacity utilisation. It appears that a transport operator has very limited ability to better consolidate goods within its vehicles, unless its contractors offer an operational environment where this is possible. This paper suggests that a platform be established that will enable transport purchasers (contractors) to identify synergies in their logistical flows. This should help to move away from one-vehicle-to-one-customer arrangements, and develop an approach where a single moving vehicle’s available capacity is viewed as a service that is available for the benefit of several actors at the same time
