Utilizando um simulador de dire??o de baixo n?vel, desenvolvido especialmente para esta pesquisa, foram realizados testes de usabilidade para medir a efic?cia, a efici?ncia e a satisfa??o, diante da sinaliza??o de controle das faixas revers?veis, conforme regulamenta??es em vigor no Brasil as quais especificam apenas a marca??o horizontal e os sinais luminosos dos sem?foros. As infra??es cometidas pelos participantes durante o percurso por tr?s diferentes pistas, os relatos gravados durantes os testes e os question?rios de satisfa??o aplicados ao final foram tomados como medidas de usabilidade. Os resultados indicam que s?o necess?rias adequa??es na regulamenta??o e correspondente revis?o de pr?ticas para a obten??o da Carteira Nacional de Habilita??o para que os motoristas adquiram familiaridade com o tema faixas revers?veis e os elementos de sinaliza??o sejam suficientemente compreens?veis. / The reversal of the flow direction in certain traffic lanes has been presented as a solution to traffic congestion registered in Brazilian cities at rush hour, however, we see the need for a comprehensive and uniform sign that, in its regulations, contemplate all sign needs for drivers feeling trust and confidence to interact with it. Using a low-level driving simulator, developed especially for this research, usability tests were performed to measure the effectiveness, efficiency and satisfaction at the sign control of reversible lanes according to regulations ruling in Brazil which only specify the horizontal markings and the light signals of the traffic lights. Infractions committed by the participants during the way for three different tracks, reports recorded during the tests and satisfaction questionnaires applied in the end of them were taken as usability measures. The results indicate that are necessary adjustments in the regulations and corresponding revision of practices to obtain the National driver's license for drivers to acquire familiarity with the subject reversible lanes and signaling elements are sufficiently comprehensible.
