“…However, it remains a question as to why the number of sources in real-world systems does not reach the maximum, resulting in an exponent that does not reach the theoretical maximum of 1. One possible explanation for this phenomenon is that cities must balance efficiency and cost [35][36][37][38][39]. As the number of sources increases, the cost of implementing the system also increases [40], forcing urban systems to make trade-offs.…”

The universal scaling relationship between an attribute and the size of a system is widespread in nature and society and is known as allometric growth. Previous studies have explained that the allometric growth exponent of single-source systems is uniquely determined by the dimension. However, the phenomenon that the exponent shows diversity in some systems, such as rivers, freight transportation and gasoline stations, lacks a reasonable explanation. In this paper, we hold the view that allometric growth may originate from efficient delivery from sources to transfer sites in a system and propose a multisource transportation network model that can explain diversified allometric growth exponents. We apply this model to some multisource systems, and the results show that our model successfully reproduces the diversity of the allometric growth exponent.

“…For the subset of the cities included in the Jones Lang LaSalle (JLL) report on global cities [67], we use the available classifications of city development level assigned according to each city’s real estate, corporate occupier base and commercial stock. (These classifications were also used for the analysis in [68], where they are described in further detail.) We aggregated the cities under the JLL categories ‘Super’, ‘Matured’ and ‘Transitional’ into a single ‘Matured’ category, and aggregated the categories ‘Developing’, ‘Early Growth’ and ‘Nascent’ into the ‘Developing’ category.…”

The spatial configuration of urban amenities and the streets connecting them collectively provide the structural backbone of a city, influencing its accessibility, vitality and ultimately the well-being of its residents. Most accessibility measures focus on the proximity of amenities in space or along transportation networks, resulting in metrics largely determined by urban density alone. These measures are unable to gauge how efficiently street networks can navigate between amenities, since they neglect the circuity component of accessibility. Existing measures also often require ad hoc modelling choices, making them less flexible for different applications and difficult to apply in cross-sectional analyses. Here, we develop a simple, principled and flexible measure to characterize the circuity of accessibility among heterogeneous amenities in a city, which we call the pairwise circuity (PC). The PC quantifies the excess travel distance incurred when using the street network to route between a pair of amenity types, summarizing both spatial and topological correlations among amenities. Measures developed using our framework exhibit significant statistical associations with a variety of urban prosperity and accessibility indicators when compared with an appropriate null model, and we find a clear separation in the PC values of cities according to development level and geographical region.

“…Danzelot argues that to ensure genuine social diversity, it is necessary to structurally intervene in inter-neighborhood and inter-municipal mobility to overcome the infrastructural barriers that separate relegated, peri-urban, and gentrified areas. This concept has recently been echoed by Mimar et al (2022) in the article "Connecting intercity mobility with urban welfare" [3].…”

From the perspective of the scientific-disciplinary debate within urban planning, this research addresses the theme of the “new urban question” resulting from environmental concerns related to the climate crisis and socioeconomic issues that have now become structural. It then delves into the connection between urban environment quality and quality of life, ultimately questioning the role that territorial governance tools play in positively influencing the perception of well-being in cities. The overall objective of this contribution is to define an interpretative framework for experimental approaches in territorial governance. This overarching objective is articulated in the definition of two specific outcomes, pursued through an inductive methodology. The first one involves establishing an initial set of urban welfare indicators; the second entails defining strategies for planning, designing, and regenerating the public components of the city that could influence the indicators. Both outcomes are designed to be exportable to different territorial contexts.
