Moped-style scooters are one of the most popular systems of micro-mobility. They are undoubtedly good for the city, as they promote forms of environmentally-friendly mobility, in which flexibility helps prevent traffic build-up in the urban centers where they operate. However, their increasing numbers are also generating conflicts as a result of the bad behavior of users, their unwarranted use in public spaces, and above all their parking. This paper proposes a methodology for finding parking spaces for shared motorcycle services using Geographic information system (GIS) location-allocation models and Global Positioning System (GPS) data. We used the center of Madrid and data from the company Muving (one of the city’s main operators) for our case study. As well as finding the location of parking spaces for motorbikes, our analysis examines how the varying distribution of demand over the course of the day affects the demand allocated to parking spaces. The results demonstrate how reserving a relatively small number of parking spaces for scooters makes it possible to capture over 70% of journeys in the catchment area. The daily variations in the distribution of demand slightly reduce the efficiency of the network of parking spaces in the morning and increase it at night, when demand is strongly focused on the most central areas.

Healthcare accessibility is among the most critical challenges affecting millions, reflecting profound geospatial disparities in Latin America. This study aims to evaluate healthcare service geospatial accessibility patterns, comparing the geospatial coverage between public and private healthcare facilities in Santiago district, Panama. We first apply the Two-Step Floating Catchment Area (2SFCA) method and its extended variant (E2SFCA) to calculate geospatial accessibility indexes at public and private healthcare facilities. We then use Getis–Ord Gi* and Local Moran geospatial statistical analysis to identify significant clusters of high and low accessibility. The results reveal that public healthcare facilities still offer higher geospatial coverage than private healthcare facilities, with higher geospatial accessibility in the central zone and lower geospatial accessibility in the south zone of Santiago. These findings highlighted the location of new healthcare facilities in zones with lower geospatial accessibility coverage. This study provides reproducible methodological tools for other geographical contexts. It also contributes to improving decision-making and formulating public policies to reduce spatial disparities in healthcare services in Panama and other Caribbean and Latin American countries.

In Latin American cities, violence against women (VAW) remains critical for public health, well-being, and safety. This phenomenon is influenced by social, political, and environmental drivers. VAW is not randomly distributed; built environments—geography, ambient population, and street networks—influence criminal through spatial dependence across multiple scales. Despite growing interest in the spatial distribution of crime, few studies have explicitly explored the spatiotemporal dimensions of VAW in Monterrey. This study explores spatio-temporal patterns of VAW in Monterrey, Mexico, based on the analysis of 27,036 georeferenced and verified emergency reports from the 911 system (2019–2022). The study applies kernel density estimation (KDE), the Getis–Ord Gi* statistics, the Local Moran I index, and space–time cube analysis to identify spatial and temporal clusters of VAW. The results show concentrations of incidents during nighttime and weekends, particularly in northern and eastern sectors in Monterrey. The analysis reveals clusters in areas of high socioeconomic vulnerability. VAW in Monterrey follows predictable and cyclical patterns. These insights contribute to the design of tailored public policies and actions to improve women’s health, well-being, and safety in critical zones and timeframes. The findings also enhance international understanding of gender-based spatial violence patterns in the rapidly urbanizing contexts of the Global South.

This research analyzes gender-based violence during the COVID-19 lockdown in colonia Fomerrey 25, Monterrey, through a quantitative, spatial and exploratory approach. Through perception surveys, 911 reports (2019-2022) and an exploratory march, temporal, spatial and environmental patterns associated with the phenomenon were identified. The findings reveal peaks of violence in the months of August and December, with higher incidence on weekends and during the evenings, especially between 21:00 and 23:00 hours. The perception of insecurity is particularly high in public spaces such as the street, transportation and parks. The spatial overlap between the reports and areas of environmental deterioration (graffiti, garbage, excessive vegetation and abandoned houses) reinforces the hypothesis that urban disorder facilitates violence. More than 60% of the incidents are located within 100 m of vulnerable areas. It is concluded that it is necessary to implement situational prevention strategies that integrate urban actions (cleaning, lighting) with community policing measures. The study contributes to the design of targeted urban safety policies with a gender approach.

Quienes requieren de atención sanitaria de emergencia no pueden esperar. Las ambulancias deben llegar al lugar del suceso lo más rápido posible. Las ambulancias suelen estar asignadas a bases, que se distribuyen por toda la ciudad para minimizar el tiempo de llegada al suceso. Sin embargo, la distribución espacial de los sucesos cambia a lo largo del día, debido al ritmo y uso que las personas hacen de la ciudad. Este artículo evalúa, por medio de modelos de localización-asignación, el desempeño espaciotemporal del SAMUR-PC, el Servicio Médico de Emergencias de Madrid (España) en dos escenarios diferenciados, antes de la pandemia de la COVID-19 y durante los primeros meses de la nueva normalidad. Los resultados muestran que el sistema respondió relativamente bien al cambio de los patrones de los sucesos debidos a la pandemia, aunque hubiese sido necesario hacer algunas intervenciones para garantizar el mismo servicio que antes de la crisis epidemiológica.
