The aim of this study is to give an interpretation of the urban transformations connected to rail transit system investments; in particular the main research goal is to analyze and give a methodological support for the urban transformation phenomena government in the rail transit stations areas. The article proposes an empirical studies comparative analysis and an application in the Naples urban area, in which a new rail transit network has been developed. In particular the socio-economic transit impacts on the urban system are measured and interpretated with the support of a GIS; therefore an application of the node-place interpretative model (Bertolini 1999) is proposed in order to support transit–land use planning processes in the stations areas.

Rail transport investments can influence housing market trends, as demonstrated in the literature. However many empirical researches highlight that different results can derive from different urban context applications and that each case should be threaten separately. It is for this reason that this paper is focused on the single case of the city of Naples, where many rail transport investments have been carried out in the last decades. The aim of this study is to give an interpretation of the housing values changes due to the opening of new metro stations. This study applies GIS tools in order to show the spatial distribution and the intensity of rail impacts in different areas of the urban system from 1994 to 2004. This study shows that the extent of the impacts varies from place to place and the effects intensity requires the presence of several complementary factors such as central location of the new stations and the presence of urban planning policies in the transit corridors. This again testifies how housing market is strictly related to the infrastructures investments planning and urban design.

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.

This article reviews and assesses the various survey techniques that have been used in studies in which data have been collected to obtain an understanding of road-based urban freight transport activities. The review identified 162 such studies in 18 countries over the last 50 years, and 12 different types of urban survey technique. In the studies reviewed, establishment surveys have been the most commonly used technique, followed by freight operator surveys, vehicle observation surveys, driver surveys, roadside interview surveys, and vehicle trip diaries. Few examples of other survey techniques (commodity flow, parking, global positioning system, supplier and service provider surveys) were identified. Establishment and vehicle observation surveys have the potential to offer insight into a wider range of issues associated with urban freight deliveries and collections to and from establishments in a specific urban area than the other survey techniques reviewed. These two survey techniques can provide insight into the frequency of goods vehicles deliveries and collections by time of day and day of week, the activities involved in the loading/unloading process, and the freight requirements of individual establishments. However, all 12 survey techniques provide insight into varying aspects of urban freight operations and various combinations are therefore likely to be used in future studies.

The objective of this study is to better understand why selected urban freight solutions represent innovations that are technically feasible, economically profitable in different contexts, sustainable, transferable, and with tangible beneficial impacts. A total of 15 solutions are evaluated in the fields of Urban Consolidation Centre, clean and electric vehicles, IT solutions, use of urban waterways, and others. Three solutions are analysed more thoroughly, the Cityporto Padova, the Basel Exhibition Centre logistics support system, and the Berlin laboratory area test of the Bentobox. This paper ends with a transversal analysis of the solutions observed, and with methodological conclusions.

Urban regeneration in Western countries can count on a long-lasting tradition of experiences in which civil society has played a fundamental role in counterbalancing the system of power, resulting in profound urban governance readjustments. This has been the result of the increasing centrality of horizontal alliances between citizens and associations involved in urban affairs since the late 1960s in the West. Similar theoretical frameworks have been applied in China. However, these have frequently resulted in conceptual shortcuts that depict civil society as immature or lacking and the state as authoritarian. This paper will explore whether these categories are still entirely valid to urban regeneration in China. While the regime has traditionally prevented horizontal linkages of associations in urban governance (supporting their vertical integration to ensure a certain degree of soft control), there are signs of change. In particular, three cases of urban regeneration in historic areas will be used to discuss the changing role played by civil society in China. The ultimate goal is to examine whether horizontal linkages across groups of heterogeneous citizens are arising at the micro-level of urban governance.
