Análise da variação da temperatura de superfície em relação à intensidade de trânsito na área urbana de Francisco Beltrão-PR

Abstract

The urbanization process, combined with the increasing impact of human activities, has changed the characteristics of the urban environment, contributing to the formation of heat islands. In these areas, temperatures are higher than in surrounding rural regions, due to the density of buildings, types of paving, reduction of green areas and also the intensity of vehicle flow in urban centers. Heat islands affect the quality of life of the urban population. This study aims to analyze the relationship between surface temperature variation and traffic intensity on the main roads of Francisco Beltrão-PR, a municipality that presents evidence of the phenomenon of urban heat islands. Using remote sensing tools and geoprocessing techniques, the surface temperature and the intensity of vehicular traffic were mapped, and the images were subsequently overlaid in order to relate these processes. The results showed that roads with the highest vehicle flow recorded average surface temperatures above the average recorded in the entire city, with a percentage increase of 7.1% and, in some cases, exceeded the temperatures recorded on roads with less or no traffic, evidencing a relationship between vehicle flow and the increase in surface temperature.
