“…The distribution of variables related to spatial segregation in Santiago de Cali is consistent with the work presented by Mayorga et al [7] regarding the existence of clusters of areas with a marked socioeconomic deficit and multiple concentrations of PN located mainly in the urban margin of the city in contrast to central areas with a low incidence of poverty, showing a core-periphery-type behavior, with similar characteristics to the case study by Cai et al [33]. The findings reinforce the hypothesis of Mayorga [8] in consequence with what was proposed by Tiznado-Aitken et al [3], Pérez-Campusano [9], Rodríguez and Arriagada [46], and Feres and Mancero [10] regarding the possible existence of housing segregation in the periphery in clusters of areas with overlapping neighborhoods with unsatisfied basic needs, low socioeconomic classification, and PN concentration.…”

“…Latin America presents the highest urban growth rate, close to 80% [1], concentrating between 20% and 30% of the population in informal settlements [2]. This widespread growth and high social segregation exacerbate mobility problems in peripheral areas [3]. From a spatial perspective, the distribution of areas with unfavorable conditions in Latin American cities such as Santiago de Cali is concentrated at the urban margins and generally coincides with hilly geographies with high slopes, which configure spaces with self-managed infrastructures and precarious public service supply in all territorial dimensions, including public transport service, access to urban facilities, and job acquisition [4,5].…”

Social Inequality in Popular Neighborhoods: A Pre- and Post-Pandemic Perspective from Joint Accessibility

et al. 2023

The existence of barriers to accessing essential urban opportunities leads to differentiated use of the territory, which can generate social fragmentation. Several authors highlight the role of public transportation services for reducing inequality gaps by providing connections between origins and destinations. The COVID-19 health emergency in 2020 highlighted the complex situation faced by disadvantaged populations in coping with crises in the absence of transportation services. Considering four popular neighborhoods in Santiago de Cali, Colombia, as a case study, patterns of public transport provision, the potential for access to opportunities, and joint accessibility patterns for 2015 and 2021 were evaluated through methods based on spatial analysis. A decrease in public transport provision of approximately 25% and an increase in travel times close to 23 min were detected by 2021. The results show deficits in the provision of transportation services and low accessibility in the study area and reinforce the hypothesis raised about the existence of housing segregation and spatial inequality located on the city’s urban edge, which are marked in both scenarios.

“…Recent studies highlighted the significance of datasets on urban accessibility. These studies were conducted on various areas by considering the correlation between urban form characteristics and accessibility and factors, such as time, distance, average speed, and transportation services, associated with traveling to destinations within a city [62][63][64][65][66][67]. Referring to the United Nation s SDGs [68], several studies have begun including walking accessibility by focusing on travel modes that yield the lowest carbon emissions; these studies have also addressed limiting the travel range in terms of the duration and distance while examining the diversity of travel patterns within this range [33,[69][70][71].…”

A Comparative Analysis of Museum Accessibility in High-Density Asian Cities: Case Studies from Seoul and Tokyo

2023

We investigated the relationship between urban accessibility of museums in the urban spaces of Tokyo and Seoul within limited travel distances. Similarities and differences were identified in the museum accessibility between the two cities. The urban accessibility of museums was set as the dependent variable, calculated via space syntax. For the spatial accessibility of museums, five walking ranges (1000–2000 m) were set as independent variables, with a distance of 250 m as the basic unit. Data normality and independence of the derived data were checked, and polynomial curve fitting was performed to interpret the accessibility of museums in each city. A comparative analysis was conducted on museum accessibility. The results show areas with a high concentration of museums in Tokyo and Seoul partially deviated from the center of the urban hierarchy. The urban and spatial accessibilities of museums in both cities quantitatively correlated with limited travel distances. Museum visitors in Tokyo were more likely to have relatively free-flowing routes in the city. The museums in Seoul had a lower overall accessibility than those in Tokyo, and travel patterns and routes to these museums were likely to be restricted when located in urban areas and consequently resembled a forced movement pattern.

“…The core areas within urban centers constitute vital components that prominently reflect urban characteristics. Presently, numerous urban planning and transportation studies have designated the urban core regions as focal points of their investigations [27][28][29][30]. This underlines the pressing need for studies that uncover and elucidate community structures within these essential urban zones.…”

Examining the clustering characteristics and fluctuations within urban areas during peak hours through the lens of bike-sharing is of utmost importance in the optimization of bike-sharing systems and urban transportation planning. This investigation adopts the principles of urban spatial interaction network construction and employs streets as the fundamental units of analysis to model bike-sharing activities during morning and evening peak hours within Beijing’s six central districts. Subsequent to this, a comprehensive analysis of the network’s structural attributes was carried out. A Walktrap method, rooted in modularity analysis, was introduced to discern and scrutinize the clustering patterns and characteristics of communities within the network across different temporal intervals. Empirical findings reveal a predominant usage pattern of shared bicycles for short-distance travel during both morning and evening peak hours. Notably, distinctive community structures manifest during these periods, characterized by two large communities and multiple smaller ones during the morning peak, while the evening peak showcases a single large community alongside several medium-sized and smaller ones. Moreover, the extended interaction radius points to an expanded geographic range of interactions among streets. These findings bear significant implications for the management of urban transportation, bike-sharing enterprises, and urban residents, proffering valuable insights for the optimization of bike-sharing schemes and transportation strategies. These research findings not only contribute to enhancing urban transportation planning and bike-sharing systems but also provide robust guidance for advancing more efficient and sustainable urban transportation solutions, thereby fostering the sustainable development of cities.
