“…From the analysis of the keywords of the papers of the review (Figure 2), conducted through pivot tables, beyond the terms included in the search strategy (GIS, VGI, PPGIS, Crowdsourcing and Transport), the words "Accessibility" [28][29][30][31][32][33], Smartphone [34][35][36][37][38] and "Activity Space" [39][40][41] emerge. In particular, GIS are fundamental to visualize the impact of transport solutions in terms of accessibility, and there is a growing literature on transport studies related to this topic [42][43][44][45]. Besides, combining crowdsourcing, sensing and open data can foster accessible and smart city development, e.g., by providing personalized paths to users with special needs [46].…”

Transport decision-making problems are typically spatially based and involve a set of feasible alternatives with multiple evaluation criteria. Besides, transport decisions affect citizens’ quality of life, as well as specific interests of general stakeholders (e.g., transport companies), thus needing a participatory approach to decision-making. Geographic Information Systems (GIS) have the ability to visualize spatial data and represent the impact of location based transport alternatives, thus helping experts to conduct robust assessments. Moreover, with the recent diffusion of Volunteered Geographic Information (VGI) and development of Public Participatory GIS (PPGIS) platforms, the process can be enhanced thanks to the collection of a large amount of updated spatial data and the achievement of an active community participation. In this study, we provide an overview based on a structured literature review of the use of VGI and PPGIS in transport studies, exploring the fields of application, role played by GIS, level of public involvement and decision stage at which they are applied. From the overview’s results, we propose a general framework for the evaluation of transport alternatives using GIS from a multiple stakeholder point of view; the main conclusion is the usefulness of the integration between Public Participation, GIS and quantitative evaluation methods, in particular Multi Criteria Decision Analysis, in order to foster technically sound and shared decisions.

“…A public transport network model can help to identify the spatial gap between transit service areas and low-income areas that need access to transit and other social needs [52,53]. This can help to improve the accessibility loss and address the nondiscriminatory dimension of transportation [54] Another alternative is to provide subsidized units in unaffordable locations with a transportation allowance that can compensate households for higher transportation costs. Such initiatives can ensure transportation equity.…”

This national study is an effort to measure transportation costs and affordability for the major Housing and Urban Development (HUD) housing assistance programs since the transportation costs are the second largest expense of American households. This study estimates transportation costs for 76,000 address level properties from seven major HUD-designated affordable housing programs. Our transportation cost models are tailored for low-income households and account for built environmental determinants of travel, known as D variables, at the disaggregated level. We found that more than 44% of these properties in 326 U.S. metropolitan areas are unaffordable in terms of transportation costs. That could result in a waste of over $37.9 billion HUD spends annually to run these programs and subsidize housing for low-income families while some of these families spend substantial amount of their income on transportation. Our findings suggest that the provision of subsidized housing in mixed use, and transit-served neighborhoods would help low-income households to reduce their transportation costs even in auto-oriented sprawling regions. This study concludes with policy recommendations to local and federal governments and transit agencies on ways to incorporate transportation parameters to ensure true affordability for low-income residents of subsidized housing.

“…The growing attention to sustainable development has underlined the importance of accessibility as a valid criterion for each of the three pillars of sustainability (economic growth, environmental quality and social equity), considering it a key concept in transport planning [1]- [3]. Therefore, it has a decisive role in the processes of planning relations between port systems and urban areas of context.…”

In recent years, there have been several changes that deeply affected the port-city relationship, due to the evolution of maritime transports, traffic volumes and port infrastructures. Thanks to the expansion of the cruise and yachting sectors and the redevelopment of waterfront and port spaces, shared areas have assumed mixed functions and activities that are attractive for passengers/tourists but potentially also for other users, such as citizens. Often, the unplanned distribution of these heterogeneous functions and activities results in overlapping and intersecting flows of freights/passengers, with the generation of criticalities for vulnerable users. Commonly, each passenger/tourist, and generally more pedestrians, are independent decision-making units, and their route choices depend not only on their trip destination but also on the on the attractiveness of the existing activities, on the geometric characteristics of the path and, generally, on its Level of Service (LOS) and quality, contrary to freight routes, which are generally based on minimum generalized cost values. Thus, having a good non-motorized accessibility is a determining factor for port-city sustainable development. This paper focuses its attention on pedestrian flows in port-city areas and the construction of a methodological framework to evaluate nonmotorized accessibility. The framework analyses the quality of pedestrian displacements, both through the LOS and a utility measure, by taking advantage of Geographic Information System (GIS) tools. The methodology has been tested on the case study of Catania, a medium-sized city located in the south of Italy, whose port is located in an area that has a strategic role due to its proximity to the historic centre. The proposed framework can contribute to providing a guide to transport and urban planners, local and port authorities and decision-makers in port-city planning, identifying criticalities and solutions to enhance the non-motorized accessibility and sustainability of the port systems and urban areas.
