Agregação de dados para análise da caminhabilidade: um estudo empírico
Palavras-chave:
Caminhabilidade. Ambiente Construído. Agregação de Dados.Resumo
Uma das estratégias para avaliar a relação entre o ambiente construído e comportamentos ativos é a caminhabilidade, definida como a medida em que o ambiente construído apoia e incentiva a caminhada. Considerando tal cenário, a agregação de dados é fundamental, porém, ainda existem desafios metodológicos e uma latente falta de evidências experimentais sobre as unidades de agregação adequadas para a caminhabilidade no Brasil. Desta forma, o objetivo desta pesquisa é analisar unidades espaciais de agregação de dados para a mensuração objetiva da caminhabilidade e suas variáveis individuais no contexto de uma cidade brasileira. A partir da sistematização da caminhabilidade objetiva, através de um índice, em diferentes unidades de agregação de dados, e.g.: setor censitário e buffers de rede com raios de 200, 400 e 600m, uma análise de variabilidade e dispersão de dados foi conduzida. Inferiu-se dos resultados estatísticos que buffers de 400 e 600m, dimensões mais próximas de distâncias caminháveis médias, foram mais eficientes. Este estudo contribuiu metodologicamente para o avanço de abordagens contemporâneas para a compreensão da caminhabilidade por meio da análise quantitativa.
