This paper examines road freight transport activity and its relationship with facility location, logistics management and urban form through an analysis of 14 selected urban areas in the UK. Improved understanding of this relationship will assist planners when making transport and land use decisions. The findings suggest that several geographical, spatial and land use factors have important influences on freight activity in urban areas. Commercial and industrial land use patterns affect the types and quantities of goods produced, consumed, and hence the total quantity of freight transport handled. This also influences the distances over which goods are moved and by what specific mode. There has been relatively low growth in warehousing in many of the selected areas over the last decade compared to the national average as well suburbanisation of warehousing in some locations. This affects the origin and destination of journeys visiting these facilities and typically increases the distance of such journeys. A greater proportion of road freight has been shown to be lifted on internal journeys in large urban areas than in smaller ones. Journeys within urban areas have been shown to be less efficient than journeys to and from the urban area in the 14 locations studied due to the much smaller average vehicle carrying capacities and lower lading factors for journeys within urban areas. The length of haul on journeys to and from urban areas studied was found to be greatest for those areas with a major seaport and/or which were geographically remote. This affects the road freight transport intensity of goods transport journeys.

This paper examines the development of road freight transport operations to, from, and within London, from medieval times to the present. Until the twentieth century, road transport was the dominant mode within London but was less important for goods moved between the rest of the country and the capital. However, since the mid-twentieth century, road transport has also dominated goods movements to and from London, mainly through technological developments in goods vehicle speed and size. Since the introduction of a Mayor of London in 2000, there has been much interest in the efficiency and sustainability of road freight transport measures at a London level. Analysis suggests that present day journeys from London generate approximately four times fewer vehicle miles per tonne lifted than in the 1830s and nine times fewer than in the 1690s.
