Avaliação de usabilidade da sinalização de controle de faixas reversíveis utilizando um simulador de direção

Abstract

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.
