This report builds on a conceptual framework developed by McKinnon (2007) for analysing the performance and impacts of freight transport. This framework is used to analyse the performance of road freight transport by heavy goods vehicles (HGVs) in Britain over the period from 1984 to 2007 using data from the Continuing Survey of Road Goods Transport. The efficiency and intensity of HGV operations are assessed. The determinants that have led to the changes in HGV key variables (including length of haul, vehicle carrying capacity, lading factor, empty running) are considered. A forecast of the future level of HGV activity (in terms of vehicle kilometres travelled, fuel consumed and CO2 emissions) in 2020 is presented.

This report contains detailed analysis of road freight transport by heavy goods vehicles (HGVs) in London and its intensity and efficiency. Using a conceptual framework for analysing the performance and impacts of freight transport it presents results for road freight transport in London between 2005 and 2007.

There has been much discussion since the mid-1980s about the relationship between transport and urban form. However, all of this body of research has concerned itself with passenger transport (i.e. the movement of people). This report is intended as an initial investigation into the relationship between road freight transport and urban form. Important trends in road freight transport and logistics and the land use associated with these activities are discussed. Data about road freight transport activity by heavy goods vehicles (HGVs) in Britain that has been disaggregated from a UK government survey is analysed to investigate the nature of urban freight operations in sixteen selected urban areas. This includes analysis of the efficiency and transport intensity of these operations on journeys to, from and within each urban area. Scenarios concerning urban freight operations based on reductions in length of haul, and improvements in vehicle lading factors, vehicle carrying capacities and empty running are constructed in order to investigate the potential effect of such changes on the vehicle kilometres performed on journeys to, from and within the sixteen urban areas.

The subject of this book is the new scientific research in the field of modelling the interaction between land use and transport (LUTI modelling). Transport and the location of activities in space have been important themes of study in engineering, social sciences and urban and regional planning
