| dc.description.abstract | In Taiwan, drunk driving is regarded a severe societal problem in large measure because of the very large number of victims it produces each year. Because the breakdown and absorption of alcohol seriously damages the vehicular operation, we comprehend the importance of the drink driving detection device, which can help reduce the occurrence of drunk-related accidents. We have utilized a Driving Simulator to determine the influence of blood alcohol concentration (BAC) on the driver performance and physiological functioning in the present study. As a result, the relationship between drunk driving and driving performance has been investigated, and the criteria to identify drunk driving by driving performance, established.
We conducted all the research with the device Driving Simulator decided by stimulating real- driving situations.Kai Wei according to Taiwan’s legal limit of alcohol (0、0.15、0.25、0.55 mg/l), we, in this study, have done 84 experimentation of stimulating drunk driving, having obtained and analyzed these statistics containing NASA-TLX, physiological state, driving effects and so on.
In this study, higher breath alcohol concentration would cause lower Oxygen concentration, higher average heart rate and slightly lower blood pressure. At the same time, we investigated the changes of driving in a high-load environment are more than ones of driving in a low-load environment. Importantly, because BAC had great influence on five driving effects including standard deviation of the depth of the accelerator, of the speed, of the vertical acceleration, of the steering wheel angle and of the lateral acceleration, without doubt, it plays a control factor in the Blood Alcohol Tests.
All in all, our study has defined the basic functionality of major driving effects that can be a significant factor on the design of Breathalyzers to detect alcohol. After all, considering a strict legislation to correct improper drunk drinking, we must go on obtaining detailed statistics to strengthen the standards of Blood Alcohol Tests.
