Análise computacional de densidade construída e de diversidade de usos em centros urbanos: uma aplicação de CityMetrics na cidade de Juiz de Fora, Minas Gerais - Brasil

Abstract

This investigation focuses on the elaboration of a computational analysis implemented through the association between parametric modeling and algorithmic logic - or simply algorithmic-parametric logic (LIMA, 2017) - of two variables that make up the urban space. More specifically, this research presents a quantitative analysis on the panorama of urban density and the diversity of uses in the city of Juiz de Fora (Minas Gerais), developing a narrative review about these aspects, presenting indicators that enable an objective analysis and, finally, presenting a computational implementation of the CityMetrics system (LIMA, 2017), aimed at developing an analysis of urban density and diversity of uses in three areas of study. The elaborated narrative review allowed us to understand that both urban density and diversity of uses can be used computationally as instruments to guide urban projects, presenting themselves as fundamental characteristics for a more sustainable urban planning. The diversity of uses associated with high urban density is presented as fundamental aspects to make the paradigm of urban compactness viable, promoting the overlap of different uses within spaces with greater urbanity. The results found to reinforce the potential of the application of computational resources as tools to support urban analysis tasks and allowed to identify, in two different analysis scenarios, the relationships between the urban form and the indicators evaluated in the studied areas, promoting reflections about urban compactness paradigm; the results obtained; the methodology adopted, its limitations and weaknesses; and the challenges of managing contemporary cities. This investigation aims to contribute to the area of urban planning by encouraging a more fruitful use of computational resources, in addition to reinforcing the importance of specific studies on aspects of urban density and diversity of uses, to produce urban projects with more quality.
