Abstract

As China has become more attractive for foreigners to travel or work, some Chinese-English bilingual guide signs have been adopted on the highways for the convenience of foreign drivers. This research examined the effectiveness of Chinese-English bilingual guide signs on highways in China for drivers with different language backgrounds. The study involved three different groups of participants: Chinese (Group C), foreigners who passed the Chinese proficiency test HSK (Group FC), and foreigners without Chinese proficiency test (Group F). A driving simulator and an eye tracker were used to obtain eye movement and driving behaviour data for both monolingual and bilingual guide sign scenes. The results showed that, for Groups C and FC, their performance in the two scenes had little difference when the number of Chinese place (destination) names on the sign was 5 or less. However, the performance of Groups C and FC in the bilingual guide sign scene was worse than that in the Chinese guide sign scene when the number of place names exceeded 5. Moreover, the participants' performance worsened as the number of place names increased for all different groups within the same scene. Thus, the threshold of the number of place names for bilingual guide signs on highways appears to be 5. Actually, the English place names on the bilingual guide signs did not have much practical effect on the drivers, since the letters of the place names were too small to be quickly seen and the translation was inaccurate.
