Proposta de construção de indicador de caracterização da acessibilidade na região metropolitana de Fortaleza

Abstract

Understanding problems is essential in developing appropriate solutions to urban mobility and accessibility issues. Thus, indicators that may characterize and diagnose such problems should be better investigated. This work proposes an indicator for the characterization of accessibility based on the logsum, commonly used as a measure of consumer surplus, presenting features that favor its use as a transport system’s performance measure. The indicator’s proposition is referenced on a general representation of the mobility and accessibility problem setting, as well as on a typology of accessibility problems based on equity and sustainability principles, verifying its applicability in Fortaleza’s Metropolitan Region. The conclusion is that the proposed method allows the estimation of adequate indicators to analyze accessibility problems, provided that in the weighted logsum measurement, as well as in the definition and calibration of the utility functions, one considers the specificities of each type of problem to be characterized and diagnosed.
