Within the scientific debate on urban regeneration, this paper intends to question possible planning techniques to address the implementation of widespread regeneration interventions in obsolete residential areas within medium-sized European cities, with particular attention to constructing a cognitive framework to locate redevelopment interventions. The widespread urban regeneration approach has yet to be sufficiently explored in the scientific literature, which focuses much more on replacing large derelict areas, though it seems particularly relevant for research and urban practice. This paper aims to illustrate a methodological framework for defining obsolete and degraded areas (at the block scale) suitable for redevelopment. Various criteria are considered, e.g., land use, buildings’ dating, state of preservation, population density, public spaces, and facility provision, and degree of accessibility. The methodological framework is then tested in the medium-sized Italian city of Parma. Data set parameters and threshold values to quantify the previously introduced criteria and perform GIS-based statistical and spatial analysis. The results show 96 areas potentially in need of regeneration, providing an opportunity to reflect on the criteria of suitability and priority for transformation and the framework of past and future planning scenarios.

Within the smart city debate, this paper aims to reflect on whether and how medium-sized Italian cities are organizing their smart transition technically as well as administratively. The smart city concept was developed in the 1990s when major European cities began a smart transition through widespread urban regeneration projects and the introduction of advanced technologies applied not only to the physical city but also to governance, policymaking, and communication, involving multiple sectors of city administrations. In the last decade, medium-sized cities have also started this transition process, although with lower emphasis than metropolitan cities. In most medium-sized Italian cities, this transition, in accordance with national and regional guidelines, has sometimes led to competencies reorganization within local governments. Within this framework, the paper examines the tools with which medium-sized Italian cities’ administrations address the smart transformation in their territories, comparing a sample of 10 cities in Emilia-Romagna and considering policymaking, governance structure, past and current projects, and communication transparency. The expected result is therefore a systematic review of experiences to reconstruct a complex picture of the political and administrative choices that have led to the implementation or setting in motion of smart transformation processes to draw some useful lessons.

How can urban policies and planning approaches help in achieving a safer mobility and carbon reduction in the transport sector? The attention of planners and policy makers towards the promotion of sustainability and reduction of environmental impacts has grown in recent years. This paper investigates the role that Urban Planning plays in the long term towards a safer and climate friendlier mobility, highlighting the need for integrated approaches gathering spatial planning and mobility management. After a review of several urban policies and planning strategies, initiatives, and approaches, mainly based on the urban scale, the paper presents an urban regeneration case study leading to an increase of pedestrian accessibility at the neighborhood level. This can be seen as a support tool to foster sustainable, safe, and climate friendly mobility in cities. The results of the performed analysis show a dependency of accessibility from two different factors: the distribution of services and the capillarity of the soft mobility network, which can contribute to creating a more walkable space.

The paper adds to the debate on urban transformation, which plays a significant role in improving quality of urban life and liveability of public spaces, as also stated in UN Sustainable Development Goal No. 11. The research aims to test a methodology for identifying an abacus of urban regeneration interventions to enhance attractive and critical nodes through accessibility and inclusivity. The quality of the system of connections between polarities, the promotion of active mobility, zero soil consumption and the renaturalisation of urban spaces are fundamental criteria to define urban regeneration solutions. The proposed approach develops on two levels: a GIS-based spatial analysis of urban data and a participatory process. The innovative planning process is tested on the San Leonardo neighbourhood in the Municipality of Parma, Italy, which allows us to verify the potentials and limitations of the procedure, identifying future work perspectives. Moreover, the application allows us to check the replicability in other urban contexts, possibly envisaging other applications to more case studies. Our results consist of the identification of the vocations and the critical aspects of nodes and axes to regenerate urban space in medium-sized and large cities’ suburbs.

Energy saving is the most sustainable solution in the long run to achieve the 2020 goals and mobility is one of the highest energy-consuming activities in our towns. The way people move in the urban environment is manageable through several policies, strategies and actions. Parking management is an important strategy in most planning activities, those addressing land use management as well as traffic plans. Private parking lots (usually at the origin of trips) are planned with a minimum standard quantity in most countries, but there are some good examples where a maximum amount of parking is ruled by plans, in order to discourage residents from possessing too many cars! The availability of public parking places (at the destination of the trip) and their fees have a direct influence on modal choice and so on inter-modality, as the economic sustainability of private motorised mobility is also influenced by economic estimations. Several options in managing public parking regulations can influence mobility patterns, such as regarding location, parking fees and time-related policies. The paper proposes a methodology for the analysis of the space-time relations between public parking and individual travel choices. The methodology has been assessed in the case study of Brescia, in northern Italy. First of all, the location and the density of parking areas within the city have been mapped to show the spatial coverage of car parking supply. Then, the time variable has been considered, to illustrate the degree of use of each parking area during the day—thus showing modal choices and their variation in time and space. The results of the analysis can be extended to similar situations as the methodology has a broad application. The final goal of the research, rather than simply monitoring parking use, is to encourage sustainable mobility through the management of parking supply in urban areas and so to foster energy saving policies.
