Report produced as part of the Green Logistics project (EPSRC and Department for Transport funded). This report is based on a review of studies in which data has been collected to obtain an understanding of road-based urban freight transport activities and patterns of operation. Studies from the UK and other countries have been included in this review. While it may be thought that relatively few such studies have been conducted, approximately 60 such studies have been identified as taking place in the UK and approximately 100 elsewhere since the 1960s. In addition, other studies have been carried out in order to assess industry and policy maker opinions about urban freight transport , however this type of study and survey work is not the focus of this report. Gaining an understanding of road-based urban freight transport activities is an important element in determining the current sustainability of such activity (in economic, social and environmental terms) and how best to go about enhancing its sustainability. By reviewing the existing survey work in this subject it has been possible to draw together the methodologies developed and implemented. This should therefore be of help in understanding which techniques are most commonly used, the strengths and limitations of the various techniques, and in assessing the most suitable urban freight survey techniques for a given study.

Report produced as part of the Green Logistics project (EPSRC and Department for Transport funded). This report contains examples of survey forms used in urban freight studies both in the UK and overseas. The studies from which these examples have been drawn range in data from 1970-2008. The purpose of the report is to provide insight into the types of questions used in different survey techniques and also into the design of survey forms. It is hoped that bringing together in a single document these examples of urban freight survey forms will be of use to researchers involved in such studies in future in planning and designing their survey work. Examples of several different types of survey techniques are provided including: Establishment surveys -- Commodity flow surveys -- Freight operator surveys -- Roadside interview surveys -- Driver surveys -- Vehicle observation surveys -- Parking surveys -- Vehicle trip diaries -- Service provider surveys

Report produced as part of the Green Logistics project (EPSRC and Department for Transport funded). This report is based on a review of UK studies in which data has been collected to obtain an understanding of road-based urban freight transport activities and patterns of operation. Urban freight remains relatively under researched by comparison with passenger transport both in the UK and worldwide. However, in the UK there have been a number of studies that have attempted to investigate road-based freight operations since the 1960s. But no attempt has been made to draw together the results of these various studies and compare them. This is what is presented in this report. The report has studied the results of 30 UK urban freight studies carried out in the last decade in order to attempt to provide insight into urban freight activities in our towns and cities. It presents this current knowledge about urban freight transport activities in the UK from these studies, and compares the similarities and differences between study findings.

LGVs are of ever-greater importance in terms of the final delivery of many time-critical, high value goods and are also widely used in industries that provide a wide range of critical support services. There are almost five times as many LGVs as there are HGVs (goods vehicles over 3.5 tonnes gross vehicle weight) currently licensed in Britain. The LGV fleet in Britain is growing at a faster rate than the HGV fleet, and the LGV fleet travels more than twice as many vehicle kilometres each year than the total HGV fleet. LGVs perform a far greater proportion of their total distance travelled in urban areas than HGVs, and consume 25% of the total diesel and 3% of the total petrol used by all motorised road transport vehicles in Britain.

The paper provides a review of the light goods vehicle (LGV) fleet and its activity, with specific reference to operations in urban areas, and sustainability issues associated with the ever-growing use of LGVs. Traditionally these vehicles have received little attention but are becoming an ever-more important element of urban freight transport both for goods collection and delivery and for the provision of a wide range of critical services. Relevant literature from the UK and elsewhere pertaining to LGV operations and their impacts has been identified and utilised. The paper identifies the impacts of LGV operations in terms of economic, social and environmental impacts and presents the range of measures being taken by policy makers and companies to address negative impacts.

The paper is based on work carried out as part of the Green Logistics project1. The paper provides a review of urban freight studies that have taken place in the UK over approximately a thirty year period from the early 1970 s to the present (this is the first attempt at such a review in the UK as far as the authors are aware). Coverage of both goods collection and delivery vehicle activity and service vehicle activity is included. This review covers the survey techniques used, as well as the survey results obtained. Comparisons are made between the results of studies from the 1970 s and those carried out in the last decade in order to gain insight to changes in urban freight transport operations. The data provided in the studies reviewed is extremely important as it provides insight into urban freight operations that is unavailable from any other data source, including national freight surveys conducted by government. However, until now, the results of these studies have not been widely disseminated or compared.

The paper focuses on the role that can be played by urban consolidation centres (UCCs) in reducing freight traffic and its environmental impacts in towns and cities. It is based on the before and after evaluation of a trial led by a major stationery and office supplies company in which urban freight deliveries in central London made from a depot in the suburbs using diesel vehicles were replaced with the use of an urban micro-consolidation centre located in the delivery area together with the use of electrically-assisted cargo tricycles and electric vans. The results show that the total distance travelled and the CO2eq emissions per parcel delivered fell by 20% and 54% respectively as a result of this delivery system. However, the evaluation has also indicated that the distance travelled per parcel rose substantially in the City of London delivery area as a result of the electric vehicles having far smaller load limits in both weight and volume compared with diesel vans. But, at the same time, the trial system was able to virtually eliminate CO2eq emissions per parcel delivered in the City of London. The trial proved successful from the company's perspective in transport, environmental and financial terms. The company therefore decided to continue the operation beyond the end of the trial with it being officially launched during 2010.

Using information gathered from some 30 UK surveys undertaken over the last 15 years, this paper provides planners with an understanding of road-based urban retail freight transport activity. The findings suggest that the average High Street business could expect up to 10 core goods and 7.6 service visits per week, in non-peak trading periods with 25% additional activity during the build up to Christmas. Vans (‘light goods vehicles’) were the dominant mode, responsible for 42% of delivery activity with a mean dwell time of 10 min. Where possible, load consolidation should be encouraged by methods such as Delivery and Servicing Plans and using out-of-town freight consolidation centres to bring in goods over the last mile in shared vehicles. Where this is not possible, loading bay monitoring and control, and preferred lorry routes can help manage the movement of vehicles in and out of dense urban areas. Service vehicle activity is a significant contributor to urban freight movements and often requires vehicles to be parked close to the premises being served. Centrally coordinating elements of service provision (e.g. for cleaning, equipment maintenance, recyclate collection), or providing improved, more flexible parking provision for service vehicles could be as or more beneficial in reducing overall freight impacts than focusing on core goods deliveries. In the case of the latter, ‘pay-as-you-leave’ car park charging systems could encourage short-stay service vehicles to park off-street.

The paper presents the ‘Marginal Activity Access Cost’, an accessibility indicator providing estimation in monetary terms of the impacts on mobility and on the environment of locating a single new activity in a specific zone of the urban area. In the first part of this paper, the new indicator is presented and compared to other accessibility indicators proposed in literature. In the second part, the MAAC is validated through an application to the urban area of Rome. The paper concludes with brief remarks on using the proposed accessibility indicator as index of performance for sustainable spatial planning.

The paper extends research into the importance of freight transport partnerships by considering the role of Business Improvement Districts (BIDs) in supporting sustainable urban freight initiatives. A review of the freight transport-related work that has been carried out in BIDs in central London is included. A detailed case study of a freight project in the Baker Street Quarter (BSQ) Partnership provides insight into work carried out in the multi-tenanted office and hotel sectors. The findings of this research in terms of freight transport and logistics activity patterns at the businesses studied together with the potential freight transport solutions identified are discussed.
