RESUMO
This work aims at verifying the impacts caused to the various road user groups due to the introduction of restrictive measures towards vehicle traffic. Procedures will be developed in order to assist decision-maker traffic managers to systematize data collection and analysis. Initially, the available information from the literature on restrictive measures is organized into parking or traffic restraint measures. The measures are defined and classified, and the reasons that motivated their implementation are presented along with examples of application in different places, such as cities in Brazil and other countries. After this characterization, a tendency analysis on the resulting changes triggered by the implementation of the restrictive measures is presented, considering each road user group, hereby called ?actor?. Variables such as accessibility, traffic flow, safety, cost and environmental quality have been chosen for the analysis. The information about the variable change tendencies are systematized taking into account each actor. The evaluation of the impacts of the application of each measure is made considering two hypothetical areas: one where the restrictive measures should have been applied, and an adjacent area where no restrictions have been applied although side effects may be observed. Subsequently, a synthesis of the results achieved is presented showing improvement or worsening for the chosen variables according to the road user groups. This procedure allows the assessment of the impacts caused by the implementation of traffic restraint to each road user group. Traffic managers have encountered resistance in implementing traffic restrictive measures, probably due to the lack of technical support to a consistent decision making and to the poor understanding of the resulting impacts by the road system managers. This work aims at improving knowledge and collaborating to analysis and decision making on the implementation of traffic restraint measures by means of systematizing the information
