Walking is a sustainable mode of transport and a healthy way of doing physical activity. Walkability is a concept that has gained enormous popularity in recent years due to its potential to promote more sustainable urban environments and healthy lifestyles. This paper provides a literature review to analyze the influence of built environment attributes on walkability. The Scopus and Web of Science databases were chosen to survey the peer-reviewed documents published up to June 2020. A total of 132 documents were selected by the search. The review of these 132 documents showed that various built environment attributes were differently analyzed and assessed. More specifically, the search identified 32 built environment attributes that were assessed by using 63 measures. Intersection density, residential density and land use mix were the most used attributes for assessing walkability, namely by using objective methods, such as ratios and spatial score tools. In turn, attributes related to streetscape design and security were much less adopted in walkability assessments. This paper provides additional insights into how built environment attributes influence walkability and identifies gaps and issues that should be analyzed in-depth in the future. The review could be helpful for researchers and urban planners in developing walkability studies and in defining policies to improve walkability.
Walking is undoubtedly a sustainable and healthy mode of transport. However, the decision to walk is influenced by many built environment and streetscape attributes. Specifically, the term walkability is used to describe the extent to which the urban environment is pedestrian-friendly, usually by quantifying multiple built environment attributes at the neighbourhood scale. The present study adopts a qualitative approach to evaluate perceived walkability. Based on a questionnaire (n = 1438) administered in the cities of Bologna and Porto, this paper analyses how respondents perceived and evaluated 19 built environment and streetscape attributes. An Exploratory Factor Analysis was carried out to examine the correlations between the various attributes and to identify the underlying walkability determinants. The analysis indicated that 13 attributes were highly correlated, resulting in four determinants: (i) urban ambiance, which includes land use and street design attributes, such as land use mix, enclosure, transparency, and architectural and landscape diversity; (ii) pedestrian infrastructure, which is related to sidewalk conditions; (iii) street connectivity and proximity to community facilities; and iv) access to other modes of transport. In turn, traffic safety and security were not correlated with perceived walkability in both cities. These findings suggest that specific urban design and pedestrian infrastructure attributes should be highly considered when formulating policies aiming to create more pedestrian-friendly cities, as well as in walkability studies and when developing walkability scores and indexes.
In accordance with SDG N11.7, each city should work on providing “by 2030, universal access to safe, inclusive and accessible, green and public spaces, in particular for women and children, older persons and persons with disabilities”. This target became even more crucial during the COVID-19 pandemic restrictions. This paper presents and discuss a method for (i) assessing the current distribution and accessibility of urban green spaces (UGSs) in a city using hierarchical network distances; and (ii) quantifying the per capita values of accessible UGSs, also in light of the restrictions in place, namely social distancing during the COVID-19 pandemic. The methods have been tested in the city of Bologna, and the results highlight urban areas that suffer from a scarcity of accessible UGSs and identify potentially overcrowded UGSs, assessing residents’ pressure over diverse UGSs of the city in question. Based on our results, this work allows for the identification of priorities of intervention to overcome these issues, while also considering temporary solutions for facing the eventual scarce provision of UGSs and related health and wellbeing benefits in periods of movement restrictions.
Rural areas in Europe host more than 55% of the overall population and embed a unique and peculiar cultural and natural heritage. Nevertheless, they are facing common issues of disengagement, depopulation and economic and social crises. Rural communities are increasingly interested in setting up inclusive and participatory regeneration processes, but participatory planning experiences in rural areas are still limited. This paper introduces the Community-based Heritage Management and Planning methodology (CHMP) developed within the RURITAGE project, and analyzes and presents the results of its implementation in six demonstrators around Europe and beyond. The methodology is based on the establishment of Rural Heritage Hubs (RHH), intended as the community of local stakeholders and a physical place to run the co-creation activities. We used four types of feedback—online survey, in-presence survey, consultations and interviews with RHH Coordinators—to analyze the implementation of the CHMP. The research findings show that through built capital (RHH places activated) and through the activation of local social and human capitals (RHH communities engaged in the process), participatory processes can attract local communities and engage them into the development and the implementation of local regeneration plans, fostering heritage ownership and inclusion.
The definition and the subsequent development of eco-industrial parks (EIPs) have been deeply based on the application of industrial ecology theory, which pays specific attention to metabolic exchanges within industrial processes to address a deep reduction of limited resource consumption and a minimization of waste production in the framework of a sustainable development approach. Despite the EIPs configurations being essentially based on the overall idea of sustainability, the problem of defining their proper location inside the territory and the consequent land use model, to minimize land consumption, have not always been central in the wide range of studies and practices concerning the EIPs. Nevertheless, the specific problem of a drastic reduction of land consumption at the EIP planning stage acquires a crucial role and, therefore, needs to be carefully assessed inside the perspective of sustainable urban development. In this framework, the paper firstly aims at facing the nontrivial relationship between the EIPs’ theorizations and implementations and the reduction of land consumption by referencing specific studies and shared tools, where new developments have been favored despite the conversion and redevelopment of existing industrial parks; secondly, it focus on an Italian case study and its emblematic EIP planning processes, in order to deepen the contradictions between sustainable spatial planning and eco-industrial parks. Finally, some final conclusions will be presented, in order to integrate some main issues concerning the reduction of land consumption inside the more traditional EIP design processes.
In the European Union, more than 70% of the population lives in urban areas. Achieving more efficient and low-carbon mobility is crucial to ensuring urban systems are sustainable and tackling important challenges, such as reduction of CO2 emissions, air and noise pollution, and traffic congestion. Identifying effective strategies and design solutions that boost multimodal mobility and effective interchange among different sustainable means of transport can be a significant contribution in this area. This paper presents an easy-to-use methodology to assess the performance of policy measures and design solutions-oriented to foster modal interchange, with special regard to the configuration of the interchange hubs. The methodology is based on identifying key factors necessary to ensure an efficient multimodal interchange and the different types of interchanges that are frequently present in the urban realm. By grouping the key factors into nine different domains, and by weighing the key factors in relation to their importance, the methodology creates a decision support system to assess the performance of the current interchange, as well as of different planning and design scenarios. This methodology has been developed in the framework of the Interreg Europe MATCH-UP project and is conceived to support both designers and decision-makers whenever they have to reorganise existing transport hubs and policies, or design and plan new ones.
