The suitability of urban spaces for pedestrian use has been pointed out as one of the ways to mitigate the disastrous effects of the prioritization of motorized transport in city planning. Considering this scenario, the studies of walkability have been widely used for analysis and diagnosis of the urban space from the point of view of those who move on foot. Some authors have emphasized, however, that the most of walkability indexes developed in the last decades, despite describing well the environment, are not able to analyse properly the way how different people value the urban space. Besides, determining the relative importance of each criterion is a controversial issue. Therefore, the relative importance of each analysed attribute can vary significantly according to different groups of respondents, in such way that the consideration of the pedestrian opinion must to be incorporated methods of analysis of the walkability. Otherwise, the walkability indexes that does not consider these different perspectives may lead to unrealistic results that represent only the researcher's experience and not the many individuals who use the city space. Thus, the main objective of this research is to analyse the importance of considering the pedestrian perspective in walkabilities's studies, applying a weighted methodology that attributes a weight to the criteria considered most important for different groups of respondents: women and men (i), young, adults and elderly (ii) and people with reduced mobility. To determine the relative importance of the analyzed criteria, a multicriteria analysis model was applied: the Analytic Hierarchy Process (AHP). In order to analyse the importance of considering pedestrian opinion the results obtained by the weightes methodology were compared with the results obtained by the simplified methodology (in which the user perspective was not considered). The results pointed that, when considered, the pedestrian's opinion significantly alters the classification of sidewalks as to the level of urgency of intervention. So, its consideration in walkabilities studies is fundamental. About the relative importance of the criteria analysed, "security" was considered the most relevant aspect for all interviewed groups (55, 06%), followed by "quality of the pathway" (22,58%) and "quality of the sidewalk" (22,36%). The great importance given to "security", mainly to "public safety" emphasizes the need for investment in this area in order to encourage walking.
