dc.description.abstract | Traffic safety issue has been respected by government, automobile industry and the general public for a long time. More and more advanced vehicles have been produced with the development of vehicle design and product technology, highway design and construction also enhance the speed and circulation, promote social progress and convenience greatly. However, drunk driving has been the leading cause of death in Taiwan. Accidents caused from drunk driving has increased year by year and it comes seriously with the high alcohol concentration sometimes. Therefore, to improve and prevent drunk driving has become very important and urgent traffic safety target.
Development of high-tech electronic products which assist driver to reduce vehicle accidents is very important in the world. This study based on the idea of Advanced Safety Vehicle to develop an intelligent monitoring and detection system for drunk driving, and research with Driving Simulator, device with appropriate driving missions and driving scenes including four kinds of alcohol concentrations (0、0.15、0.25、0.55 mg/l) and three kinds of warming systems (none, voice and image, vibration). Then we obtained and analyzed these statistics containing NASA-TLX, physiological state, driving performance.
According to result, alcohol concentration had great influence on time to collision(TTC), standard deviation reaction time(RT), distance of release throttle, standard deviation of speed, and warming system caused great influence on depth of throttle, distance of release throttle, standard deviation of depth of brake, standard deviation of reaction time. At the same time, experimental results clearly demonstrated that the voice and image warming system has the best performance on three kinds of warming systems. Higher alcohol concentration would cause higher average heart rate.
All in all, we believe that the results in our study would useful to development and design of monitoring and detection system for drunk driving.
