본 연구의 목적은 음주운전으로 인한 자동차 사고를 줄이기 위한 방법으로 음주운전의 의도에 영향을 주는 여러 가지 요인들을 조사하였다. 본 논문에서는 흡연습관과 운동습관과 같은 운전자의 생활방식뿐만 아니라 사회심리학적인 요인들을 조사에 포함시켰다. 조서결과 음주운전자의 사회심리학적인 특성 중에서 행동통제력지각이 음주운전의 의도에 가장 큰 영향을 미치고, 뒤이어 음주운전의 의도에서 흡연습관, 운동습관 등의 순으로 영향을 미치는 것으로 나타났다. 이러한 연구 결과는 흡연습관과 운동습관과 같은 운전자의 생활방식이 음주운동에 대한 태도나 주관적인 규정보다 음주운전의 의도에 더 큰 영향을 미친다는 것으로 해석될 수 있다. 따라서 음주운전자 교육과정에 금연습관과 운동습관을 포함시킴으로서 음주운전을 감소시킬 수 있도록 프로그램을 개선하여야 한다.

As the main means to cope with the stubborn problem of drunk driving, the inspection of drunk driving has already been paid more attention and thus reinforced. In this paper, we model this scenario as a Stackelberg game, where the police department (called defender) allocates resources dynamically in terms of the traffic situation on the traffic network to arrest drink drivers and drivers who drink (called attacker), whether choosing drunk driving or designated driving service, expect to minimize their cost for given travel routes. However, with the number of resources are limited, our goal is to calculate the optimal resource allocation strategy for the defender. Therefore, first, we provide an effective approach (named OISDD) to fulfill our goal, i.e., generate the optimal strategy to inspect drunk driving. Second, we apply OISDD to directed graphs (which are abstracted from Dalian traffic network) to analyze and test its correctness and rationality. The experimental results show that OISDD is feasible and efficient.

Recently, occurrence of alcohol-involved traffic accidents is increasing while all the accidents by violation of law except drunk driving. Traffic accidents by drunk driving has a great external cost. In detecting drunk driving, blood alcohol content Many studies reported close correlation between blood alcohol content and traffic accidents by drunk driving. The risk of traffic accidnet increases exponentially as blood alcohol content increases. To control traffic accidents by drunk driving, decide target population. Heavy drinkers are few and responsible for a small part of the loss while casual drinkers are many and responsible for a large part of the loss. Casual drinkers need to be included in the targer population for the control of traffic accident by drunk driving. Stragegies to reduce the quantity of alcohol consumed, change the pattern of drink, such as frequency of drinking, raise of perceived risk of accident need to be sought.

본 연구는 운전자가 음주 후 운전여부를 결정할 때 가장 중요하게 고려하는 음주운전결정요인에 대해 탐색하고, 이들 요인들에 대해 음주운전자와 비 음주운전자 간 차이를 보이는지를 알아보는 것을 목적으로 한다. 이를 위하여 본 연구에서는 집단심층면접과 기존 문헌 고찰을 통해 얻은 음주운전에 영향을 미치는 인지적·사회심리적 요인들을 종합하여 설문지를 작성하였다. 전체 조사대상자는 음주운전 경험이 있는 운전자 136(남자 122명, 여자 13명)명이었다. 연구결과를 살펴보면, 우선 운전자들은 음주 후 운전여부를 결정할 때 1) 음주정도, 2) 음주 후 경과시간 정도, 그리고 3) 다음날 이동시의 불편함, 4) 집과의 거리 정도를 가장 중요하게 고려하는 것으로 나타났다. 다음으로 음주 후 운전여부를 결정할 때 중요하게 고려하는 요인들에 대해 음주운전자와 비 음주운전자 간 차이를 검증해 본 결과, 크게 세 가지 차원에서 차이를 보이고 있다. 첫째, '잘못된 신념'에 해당하는 요인들로 음주운전자들이 비 음주운전자들에 비해 음주단속에 걸리지 않을 것이라는 신념을 가지고 있으며, 음주단속과 교통사고 발생가능성을 낮게 평가하고, 자신의 운전실력을 과신하는 경향이 있다. 둘째, '목전단기이익 추구 경향성'에 해당하는 요인들로 음주운전자들이 비 음주운전자들보다 음주 후 차를 두고 갈 경우 야기되는 비용부담, 다음날 이동시의 불편함 그리고 집과의 거리 정도에 더욱 민감한 것으로 나타났다. 마지막으로 음주운전자들이 비 음주운전자들보다 마신 술의 양(음주량)에 대해 더욱 과소평가하는 것으로 나타났다. 본 연구는 이와 같은 연구결과들을 바탕으로 향후 음주운전에 대한 개선 방안을 함께 제시하고자 한다.

Objective: Drinking drive is a nationally recognized social problem. This research aimed to describe the relationship between drinking behavior and drinking drive based on the social demographic characteristics. Methods: This paper used secondary data for analyses which was derived from the national representative samples of adults; National Health and Nutrition Surveys by Korea Institute for Health and Social Affairs in 1998 and 2001. For data analyses, univariate analysis, Chi-square test and logistic regression analysis were adopted for the samples of male adults who were driving and 20 years old and more. Results: The prevalence of drinking drive varied significantly among socio-demographic characteristics. The year prevalence rates of drinking drive were 29.1% in 1998 and 16.4% in 2001. In the rates of drinking drive, males were higher than those of females in both years. By age, twenties to thirties showed the highest ratio of drinking drive(odd ratio=18.8), compared with the sixties. Related to the occupation, the persons who were engaging in farming and fishery showed the highest ratio(odd ratio=3.73) of drinking drive in comparison to the unemployed. Conclusions: People who drink alcohol frequently tended to have more experiences of drinking drive. In addition, the drivers who drink more amount of alcohol drinking were significantly associated with higher rates of drinking drive, as well. Strategy based on the socio-demographic characteristics may provide a promising prevention of reducing drinking drive. Community-based efforts, education, self-awareness and public-awareness to address drinking and drinking drive problems are effective in reducing drinking drive. Enacting comprehensive regulations which control drinking drive can reduce both alcohol use and drinking drive.

In order to prevent drink-driving by detecting concentration of alcohol from driver's exhale breath, twenty chemical sensors fabricated. The one of purposes for sensor array which consists of those sensors is to discriminate between target gas(alcohol) and interference gases($CH_3CH_2OH$, CO, NOx, Toluene, and Xylene). Wilks's lambda was presented to achieve above purpose and optimal sensors were selected using the method. In this paper, step-wise sensor elimination based on Euclidean distance was investigated for selecting optimal sensors and compared with a result of Wilks's lambda method. The selectivity and sensitivity of sensor array were used for comparing performance of sensor array as a result of two methods. The data acquired from selected sensor were analyzed by pattern analysis methods, principal component analysis and Sammon's mapping to analyze cluster tendency in the low space (2D). The sensor array by stepwise sensor elimination method had a better sensitivity and selectivity compared to a result of Wilks's lambda method.
