Methods: Seventy-six randomly selected volunteer drivers each had three times of alcohol intake (100 ml each time). After each drank, BAC was measured with gas chromatograph and driving ability was evaluated. The drivers were grouped according to age, weight, alcohol tolerance and driving experience respectively and changes in BAC and driving ability were analyzed. Results: Average BAC and the percentage of drivers showing impaired driving ability in the groups increased after each intake of 100 ml alcohol. BAC in Group≤60 kg was more susceptible to alcohol than that in Group>60 kg. When each drank, alcohol had greater influence on drivers who had comparatively shorter driving experience. Conclusion: Volume of consumed alcohol, BAC and driving ability have direct associations among one another and are all under the influence of various factors including individual conditions. To set an appropriate legal BAC limit for safe driving should take an overall consideration of all factors.展开更多

Aimed at that the traditional drunk driving detection system has low sensitivity and unable to distinguish diffuse alcohol sigmal interference. For accurate identification of pilot and crew alcohol concentration, the paper puts forward a driving intelligent identification wine system based on embedded μC/OS- II. The experimental results show that the detection sensitivity of the system has high accuracy rate, effectively prevent the purpose for the prevention of drunk driving, drunk driving has very good practical value.展开更多

Methods： This is a cross sectional study which is performed at Shiraz city of Iran. Data from motorcycle drivers were collected using a standard questionnaire in eight major streets at different times of the day. The data includes consumption of alcohol and other substances two hours before driving and some of the risky behaviors during driving. Results： A total of 414 drivers with a mean ±SD age of （27.0 ±9.3） years participated in the study. Alcohol or substance consumptions two hours before driving was significantly associated with risky driving behaviors such as using mobile phone during driving, poor maneuvering, and driving over the speed limit （both p 〈 0.001 ）. It was also associated with carelessness about safety such as driving with technical defects （p 〈 0.001） and not wearing a crash helmet （p 0.008）. Conclusion： Screening for alcohol and substance consumption among motorcycle drivers is an efficient way to identify drivers that are at a greater risk for road traffic accidents.展开更多
