다국어 초록 (Multilingual Abstract)

Objective: The purpose of this study was to investigate the effects of the secondary tasks such as sending text message (STM) and searching navigation (SN) on brake time of taxi drivers when it happen unexpected situation during driving. Background: There are so many researches that driving performance of ordinary people was affected by cell phone conversations and watching TV. But there are no researches about driving performance of taxi drivers. Method: The participants included 15 taxi drivers; 7 males aged 57.7±4.2 with 28.0±7.5 years of driving experiences and 8 females aged 56.0±2.8 with 22.7±5.2 years of driving experiences. All subjects were instructed to keep a certain distance (30m) from the car ahead and a constant speed (80km/h or 100km/h). The brake time after unexpected situation was measured. Results: The brake time was more faster during driving only than the driving with secondary tasks. Driving performance was more affected by driving with searching navigation(SN) than sending text message(STM).
