摘要

本研究藉由相關文獻探討以了解汽車煞車燈設計原則及針對台灣實際的道路交通狀況，調查導致汽車碰撞事故發生的潛在因素。針對駕駛者對於前方車輛減速時，後方車輛與前方車輛之間的車距將會急速縮短，藉由一般煞車燈與LED漸進式煞車燈，兩種不同的煞車燈顯示方式，以電腦模擬駕駛系統的實驗方式，分別測量駕駛者其煞車反應時間，加以探討比較，以期找出最佳的煞車燈顯示方式提供相關汽車煞車燈設計之參考。
經過本研究的電腦模擬駕駛實驗，漸進式LED煞車燈在駕駛者面對不同前車減速度下，煞車反應時間與傳統煞車燈比較起來平均縮短了0.625秒，除此之外經過實驗數據LSD交互影響分析，得知最佳煞車燈顯示為3階層，此改良型的LED煞車燈顯示方式，讓駕駛者開車時能更清楚地判斷前方煞車動態程度，減少其煞車反應時間，進而避免車禍碰撞事故的發生。

In this research, the design principles of the vehicle rear brake lamp were studied through relevant literature review. In view of Taiwan’s actual road traffic condition, we investigate the potential factors of the vehicle collision accident. While the front vehicle decelerates, the car distance between rear vehicle and the front vehicle will shorten rapidly. We use the systematic experiment way with computer simulation, traditional brake lamp and incremental LED rear brake lamp, two kinds of different display mode of the vehicle brake lamp, to measure the reaction time separately, and compare the result, in the hope of finding out the best display mode of the vehicle brake lamp to provide the criterion and suggestion for the design reference in the rear brake lamp.
The results find out that the average reaction time for the incremental LED rear brake lamp is shorter than traditional brake lamp for 0.625s, and the statistic data after experiment use LSD to analyze the reaction time of incremental LED rear brake lamp, we knew that the best display level is three. This display mode let drivers to judge the degree of the brake of the front vehicle more clearly while driving, reduces the reaction time, and then avoid the collision accident.
