Abstract

Understanding problems is essen*al in developing appropriate solu*ons to urban mo-bility and accessibility issues. Thus, indicators that may characterize and diagnose such problems should be be@er inves*gated. This work proposes an indicator for the charac-teriza*on of accessibility based on the logsum, commonly used as a measure of con-sumer surplus, presen*ng features that favor its use as a transport system’s perfor-mance measure. The indicator’s proposi*on is referenced on a general representa*on of the mobility and accessibility problem seDng, as well as on a typology of accessibility problems based on equity and sustainability principles, verifying its applicability in For-taleza’s Metropolitan Region. The conclusion is that the proposed method allows the es*ma*on of adequate indicators to analyze accessibility problems, provided that in the weighted logsum measurement, as well as in the defini*on and calibra*on of the u*lity func*ons, one considers the specifici*es of each type of problem to be characterized and diagnosed.
