accessibility and socioeconomic exclusion

This article is a study on accessibility to urban parks in Porto Alegre, Rio Grande do Sul, Brazil, which aims to investigate how different social classes access these spaces. For this purpose, a methodology that considers travel times was used to determine the spatial accessibility of places/locations, considering the spatial distribution of nine urban parks and evaluating the performance of walking, cycling, and public transport. To calculate and determine accessibility considering the cost of travel in terms of time, the RStudio software was used through the {r5r} package. Spatial opportunity maps of socioeconomic groups were generated by crossing with the accessibility data previously calculated, with the income information per hexagon, the distribution of accessibility of the population of each income level was calculated, and the weighting of the accessibility level was made. The distribution of accessibility of people located in the origins of a certain income decile was obtained, generating graphs according to travel time (30, 60, 90, and 120 minutes). The analysis highlights significant inequality in access to urban parks in Porto Alegre. Accessibility on foot is the most restricted and unequal, benefiting mainly central areas and higher income classes. Although cycling increases the reach of parks compared to walking, it still faces significant inequalities. Public transportation emerges as the most equitable mode, offering the greatest coverage and potentially reducing disparities.
