“…Several studies have accounted for the impacts of flooding on transportation (e.g. (Huang, 2020;Barros et al, 2021)). In fact, in urban areas the impact of floods on the transportation system may be immediate (Singh et al, 2018), and both the resident population and commuters are particularly exposed to several risks, including urban immobility.…”

PurposeA sustainable transportation system should represent a win-win situation: minimizing transport's impact on the environment and reducing natural disasters' effects on transportation. A well-distributed set of rain gauges is crucial for monitoring services in smart cities. However, those services should consider the uncertainties about the registers of rainfall impacts. In this paper, the authors present a case study of optimal rain gauge location based on an actual database of rainfall events with impacts on urban mobility in the city of Sao Paulo (Brazil).Design/methodology/approachThis paper presents a maximal covering location formulation and proposes a robustness analysis considering spatial location perturbations.FindingsIn this case study, the robustness of the objective function is above 99.99%. The robustness for the number of covered demand points is 88.93%, and the frequency associated with every candidate is between 11.71% and 69.49%.Originality/valueIncorporating spatial uncertainties on coverage problems is essential to provide stakeholders more realistic supporting tools and to draw different possible scenarios.

“…3D maps provide a realistic urban context in a more immersive and engaging way than 2D geographic maps [150]. They are commonly used in public security [105,[114][115][116] and architectural domains [120,[122][123][124] because they provide a sense of presence.

Developing effective visual analytics systems demands care in characterization of domain problems and integration of visualization techniques and computational models. Urban visual analytics has already achieved remarkable success in tackling urban problems and providing fundamental services for smart cities. To promote further academic research and assist the development of industrial urban analytics systems, we comprehensively review urban visual analytics studies from four perspectives. In particular, we identify 8 urban domains and 22 types of popular visualization, analyze 7 types of computational method, and categorize existing systems into 4 types based on their integration of visualization techniques and computational models. We conclude with potential research directions and opportunities.

“…In this line, Raza's (2017) [43] contribution is noteworthy, presenting a spatial data model enabling the rapid assessment of populations affected by floods, facilitating timely decision-making for humanitarian responses. Another author, Huang (2021) [44], focuses on mapping the impact of floods on urban mobility, particularly the disruption of road networks, crucial for effective damage mitigation and evacuation operations. Pappalardo (2023) [45] addresses the issue of spatial equity in flood risk management, identifying areas with high exposure and vulnerability to prioritize mitigation actions benefiting the most vulnerable populations.…”

The assessment of vulnerability to the danger of flooding, with a focus on the need for rescue and assistance from the population, is still in an exploratory scientific phase. The main objective of this research is to propose a methodology based on the issues of rescue and assistance in the face of the risk of floods and to provide a tool for its management. A series of maps is presented, indicating those territorial elements that require rescue and surveillance in a prioritized manner in a visual and accessible way for public administration. Four methodological cartographic proposals have been designed as follows: (1) a map of territory sectors with special rescue needs (dependent population and/or buildings without shelter); a map of the impact on transportation infrastructure and vulnerable areas of buildings (2); a map of vulnerability to possible disorder and looting caused by flooding events (3); and a map of the increase in the cost of deployment for rescue and assistance systems (4). As an experimental zone to test the effectiveness of these proposals, a peri-urban area of the municipality of Málaga (Spain) is chosen, which has an extensive history of severe floods. The results confirm the applied and preventive nature of the tool, which can be incorporated into flood risk management plans and local flood risk action plans developed by public administrations. The main finding of the research is the technical advancement that comes with a precise understanding of vulnerability and its resulting issues for better flood risk management.
