摘要
車道偏離警告系統（Lane Departure Warning Systems，LDWS）是一種主動性汽車安全系統，利用視覺、聽覺或觸覺等警示訊號來提醒駕駛者。隨著車內訊息系統越來越多樣化，使得駕駛者接收到不同型態的訊息，但人類對於資訊處理之能力是有限的。過去對於車道偏離警告系統之相關研究中，並未針對具有方向性及多感官型態之警示訊號呈現方式進行探討。因此，本研究將探討車道偏離警告系統之多感官警示訊號呈現方式，以評估其工作績效是否具有差異。 本研究採用模擬駕駛之方式，進行駕駛者之工作績效實驗，以多感官警示訊號（視覺V、聽覺A、視覺+聽覺V+A、視覺+觸覺V+T、聽覺+觸覺A+T及視覺+聽覺+觸覺V+A+T）等六種組合為實驗因子，探討不同性別之駕駛者對於具有方向性的警示訊號以多感官型態呈現之反應時間及錯誤率，比較駕駛者在反應不同型態多感官警示訊號時的工作績效之差異。 研究結果顯示，多感官組合V+T與V+A+T顯著縮短反應的時間，且錯誤率較低。建議往後車道偏離警告系統之警示訊號設計者可採用V+T或V+A+T等多感官組合，以提高駕駛者之反應，並減輕工作負荷。

Lane Departure Warning Systems (LDWS) is an active auto security system, which reminds the driver by the visual, auditory or tactile warning signals. With the increasingly diversified vehicle information systems, the driver may receive various information. However, people are not capable enough to deal with information. The previous researches related to LDWS don’t explore the presentation means of the directional and multisensory warning signals. Therefore, this study explores the presentation means of the multisensory warning signals in the LDWS to evaluate whether its task performance shows difference. This study tests the task performance of the driver by using the means of simulated driving. Taking six combinations of multisensory warning signals (Visual, Auditory, Visual+ Auditory, Visual + Tactile, Auditory+ Tactile, and Visual+ Auditory+ Tactile) as the experimental factors, it explores the response time and error rate of the driver of different gender to the directional warning signals presenting in a multisensory way, and compares the task performance difference of the driver when responding to different multisensory warning signals. The study results show the multisensory combinations of V+T and V+A+T shortens the response time significantly, and its error rate is relatively lower. It is suggested that the LDWS warning signal designer can adopt the multisensory combinations of V+T or V+A+T in the future, so as to improve the driver’s response and relieve the workload.
