Research has shown the influence of the guide sign information on motorists, however questions regarding the number of road names that can be presented on expressway exit guide signs is not known with certainty. The results of the study indicate that more information on an expressway exit guide sign leads to an increase in confirmation time and subjective assessments grow. From the results, an evaluative index of expressway exit guide sign information overload threshold can be determined. The results show that when the number of road names on an exit sign is six or less, motorists can perceive and understand the information on the sign faster.
