“…Second, the lack of inclusion of the time dimension in urban vitality studies. On this subject, although the application of morphologic indexes offers a rich array of dimensions and corresponding indicators [15][16][17], time-based indexes of urban vitality would also promote the assimilation of the variability concept, which refers to a dynamic attribute regarding the flexible quantity of people present in the same area at different times of the day or the week [41,78,79].…”

Urban vitality, understood as a key factor in the achievement of cities’ sustainability, shows a strong relationship with urban morphology. The city theorist Jane Jacobs suggested morphological aspects to promote vital cities in the 1960s, which remain valid in the present. However, few studies in the Andean region quantitatively exemplify this. This paper aims to test the measurement of urban vitality in a neighborhood of Quito, Ecuador, called La Mariscal, integrating Jacobs’ approach. In particular, three urban vitality indexes are evaluated with the application of GIS software using cadastral data obtained from the Metropolitan District of Quito and field data collection. Results show that context-based previous knowledge and scale of analysis are essential factors in the configuration of dimensions, indicators, and spatial representation of any urban vitality index. In the study area, land use mixture, contact opportunity, and accessibility dimensions are fundamental. Regarding indicators, the incorporation of informal small-scale commerce, the quality of sidewalks, and well-conditioned street furniture is recommended. Finally, a hybrid representation (raster and vectorial) is suggested to precisely measure urban vitality at a block scale. Altogether, by providing a comparative approach, we intend to provide a useful framework for researchers and planners to study urban vitality in Andean cities.

“…Time-based indexes of urban vitality would contribute to a more detailed understanding of morphological parameters that determine people's activities [19,52,75]. This could also promote the assimilation of the variability concept, which refers to a dynamic attribute regarding the flexible quantity of people present in the same area at different times of the day [41,78]. Moreover, the inclusion of time in measuring urban vitality may also lead to a significant relationship between people's concentration and street security [29,79].…”

Urban vitality, understood as a key factor for the achievement of cities’ sustainability, shows a strong relationship with urban morphology. The city theorist Jane Jacobs suggested morphologi-cal aspects to promote vital cities already in the 1960s, which remain valid in the present. How-ever, few studies in the Andean region quantitatively exemplify this. This paper aims to test the measurement of urban vitality in a neighborhood of Quito, Ecuador, called La Mariscal, inte-grating Jacobs’ approach. In particular, three urban vitality indexes are evaluated with the appli-cation of GIS software using cadastral data obtained from the municipality and field data col-lection. Results show that the context-based previous knowledge and the scale of analysis are es-sential factors in the configuration of dimensions, indicators, and spatial representation of any urban vitality index. In the study area land use mixture, contact opportunity, and accessibility dimensions are fundamental. Regarding indicators, the incorporation of the informal small-scale commerce, the quality of sidewalks, the street slope, and the good-conditioned street furniture is recommended. Finally, a hybrid representation (raster and vectorial) is suggested to precisely measure urban vitality at a block scale. Altogether, by providing a comparative approach, we in-tend to bring a useful framework for researchers and planners to study urban vitality in Andean cities.

“…The OLS model only estimates the coefficients of the variables on a global scale [64], which cannot reveal the spatial and temporal variation in the coefficients. Compared to the traditional GWR model, the GTWR model is more suitable for a regression analysis of spatio-temporal data by considering both temporal and spatial heterogeneity.…”

Sensing urban vitality is a useful method for understanding urban development. However, the spatio-temporal characteristics of the association between the built environment and urban vitality in Shenzhen, the youngest mega-city in China, have not yet been explored. In this paper, we examined the effects of built environment indicators on urban vitality by using spatial regression models and multi-source geospatial data. The main research findings were as follows. Firstly, urban vitality displayed a consistent high–low pattern during both weekdays and weekends. Differences in the distribution of urban vitality with time between weekdays and weekends were more significant. Secondly, the effects of various built environment indicators on urban vitality exhibited significant temporal disparities. Within a day, population density, building density, bus station density, and distance to metro stations all exhibited positive effects, while distance to the central business district (CBD) exhibited negative effects, with pronounced diurnal differences. Moreover, the effects of road network density and functional mix on urban vitality were both positive and negative throughout the day. Thirdly, besides population density and building density, road network density, functional mix, bus stop density, and distance from metro stations exhibited positive and negative disparities within the study area. Overall, distance to the CBD had a negative effect on urban vitality. This concludes that planning for urban vitality should consider the spatio-temporal heterogeneity of the association between the built environment and urban vitality.
