Evaluation and Selection of Alternatives for the Promotion of Sustainable Urban Mobility

Abstract

This study aims at the adjustment and application of a strategy to assess and select alternatives for improving the mobility conditions of a city. The approach was tested in the city of Itajubá, MG, Brazil, as follows: i) assessment of the current conditions, as given by the Index of Sustainable Urban Mobility, and ii) application of a strategy designed to indicate alternatives for the improvement of the mobility conditions in a sustainable way. The overall value of the index in Itajubá was 0.452, in a scale varying from zero to one. The comparison of this value with the results of reference cities, such as Curitiba (0.754) and Uberlândia (0.714), indicates an important difference. However, the approach seems to indicate lines of action for the improvement of mobility, given that it allows a fast identification of positive or negative points raised by the experts. Based on the results obtained, it can be assumed that the level, activity or profession of the participant will influence the results. In this case, for example, the external specialist presented a more pessimistic evaluation than the manager. Keeping in mind the viability of these responses, every change proposal must take into consideration the potential evaluator bias. It is evident that, if the number of evaluators is substantially raised, these discrepancies tend to diminish, and would also enable the analysis using mean values.
