Question

the trafic officer argued that the high accident rate was caused by drunk driving 'direcred speech'​

Answer 1

Drinking driving is responsible for a high proportion of traffic accidents. To study the effects of alcohol on drivers and driving performance, 25 drivers’ subjective feelings and driving performance data in different blood-alcohol concentration (BAC) levels were collected with simulated driving experiment. The investigation results revealed that alcohol affected drivers in many aspects, including attitude, judgment, vigilance, perception, reaction, and controlling. The analysis of accident rate showed that higher BAC level would lead to higher accident rate. The statistical analysis results of driving performance indicated that average speed, speed standard deviation, and lane position standard deviation were significantly higher under the influence of alcohol. They also had a statistically significant linear trend as the function of BAC level. The discrimination of drinking driving based on driving performance was performed with Fisher discrimination method. The results showed that drinking driving with higher BAC level was easier to discriminate from normal driving. Also, the results indicated that the three significant indicators on straight roadway could be used in the discrimination of drinking driving state. The conclusions can provide references for the study of drinking driving and the identification of driving state and then contribute to traffic safety.

1. Introduction

It has been known that alcohol use impairs driving skills and increases accident risk. It has been found that while driving under the influence of alcohol, the risk of having an accident causing injury or death increases exponentially [1]. In Europe, drinking driving is thought to be responsible for 10,000 deaths each year [2]. Alcohol-impaired driving accidents contribute to approximately 31% of all traffic fatalities in the USA [3]. In China, Li et al. revealed that about 34.1% of road accidents were alcohol related [4].

Drunk driving has a high probability to lead to serious accidents. Even with a small amount of alcohol assumption, drivers are twice likely to be involved in traffic accidents than sober drivers [5]. Therefore, many countries have been working on solutions to drunk driving for a long period of time, including publicity and education and tough drunk-driving laws. The laws have been enacted to prohibit driving after drinking and have imposed severe penalties on violators [6]. The legal limits for BAC are between 0.01% and 0.08%. The limit, for example, is 0.02% in Sweden; 0.05% in Israel, Korea, and Australia; and 0.08% in Canada, England, Mexico, and the United States. In China, driving with a BAC higher than 0.02% is defined as drink-driving and the driver will be penalized. Moreover, driving with a BAC higher than 0.08% is considered drunken-driving and it belongs to unlawful act.

I hope this is helpful to you guys.
