The objective of this master thesis is to understand how planning, normative, budgetary, and financing instruments of the urban mobility policy shaped the implementation of the Urban Mobility National Policy (PNMU) in the Urban Core of the Metropolitan Region of Curitiba, institutionalizing the concept of urban mobility, between 2004 and 2021. We begin by discussing the origins of the sustainable urban mobility concept, from which the PNMU guidelines derive, as well as the factors that configure the scenario in which the policy seeks to intervene -car-dependent cities -and its repercussions in the national context. As a theoretical framework for analysis, we borrow from public policies analysis the conceptualization of implementation processes, instruments of public action and multilevel governance. The work is a case study, using the historical construction of the policy's context, qualitative (content analysis in the systematic review of documents) and quantitative (descriptive statistics) methods, achieving internal validity of the results through triangulation of data sources. Curitiba, the pole city of the defined territorial study area, is a reference in the subject, especially for Bus Rapid Transit (BRT) creation. However, regarding urban mobility, the city and its metropolitan region currently present indicators that contrast with this deference, such as the highest rate of motorization and the lowest percentage of trips made in public transport among the largest Brazilian capitals. As a result, we observed that the linkage between planning instruments at the federal, state, and municipal levels indicates a strong induction of the sustainable urban mobility agenda by the federal government. Nevertheless, the history of mobility policies demonstrates effects of path dependence, as the continuity of planning with a focus on automobiles and the accommodation of the fleet, which starts from macroeconomic policies and reaches the street scale. The analysis of the planning instruments shows there is a relatively direct adaptation to Nacional Policy (PNMU) guidelines, due to their hierarchical linkage. However, from the analysis of budget execution and the current state of urban mobility in the territory, we observe that initiatives to democratize the road space are still timid, which tend to be consolidated through an incremental process. The institutional arrangement responsible for the metropolitan governance, however, remains distant from this process of building the urban mobility policy in the region, limiting itself so far to the indication of guidelines for the widening and extension of roads in the metropolitan region and precarious management of the metropolitan public transport. First, the work contributes to understand the casethe continuities and discontinuities of urban mobility in Curitiba metropolis agenda and what are the policy results. Also, it contributes to the urban mobility literature, bringing an analysis framework of implementation from public policy background to the case analysis, whic...
