정철우 ( Cheol Woo Jeong,),장윤식 ( Yung Sik Jang,) 한국경찰법학회 2014 경찰법연구 Vol.12 No.2

The purpose of this study is to make a better incentive policy for traffic safety through analysing effectiveness of ‘Granting license score privilege’ policy. For this study, data of about 600,000 drivers of Suwon, Gyeongi-do were collected. These data is consisted of variables such as a sex, age, the records of law violation, and traffic accidents. Among these drivers, about 20,000 drivers applied to a granting license score privilege which we called it ‘a kind milage’, and the others did not. To analyse the effectiveness of ‘a kind milage’, a covariance analysis method is conducted. The result of this study showed that a one way incentive policy to the drivers are not effective in reducing violation law and traffic accident. The applied group to ‘incentive policy’ is 6% higher in average violation law and 75% higher in average traffic accident than not applied one, This study suggested that government should ask to the drivers a certain duties to settle a better incentive policy rather than only one way incentive giving.

정철우(Cheol Woo Jeong),이상엽(Sang Yeob Lee) 한국셉테드학회 2017 한국셉테드학회지 Vol.8 No.2

본 연구는 CPTED가 범죄 두려움에 대하여 어떠한 효과를 가지고 있는지에 대한 기존의 연구결과를 대상으로 메타분석을 통하여 효과크기를 측정함으로써, 각 연구들이 제시하고 있는 서로 다른 결과를 종합적으로 분석할 수 있으며, 이를 통하여 보다 효율적인 CPTED전략의 실행에 기여하고자 하는 목적으로 수행되었다. 본 연구의 결과는 다음과 같다. 효과크기 분석을 통하여 CPTED의 전략이나 요소들 가운데에서 범죄 피해와 범죄두려움 감소라는 목적 변수에 대하여 하나라도 유의한 효과 크기를 보이는 변수는 긍정적인 효과를 보이는 것으로 ‘감시’, ‘유지관리’, ‘사회적 유대’, ‘활동 지원’, ‘영역성’, ‘활용성’이었으며, 부정적인 효과를 보이는 것으로‘물리적 무질서’,‘사회적 무질서’인 것으로 나타났다. 특히 ‘감시’와 ‘유지관리’, ‘사회적 무질서’, ‘물리적 무질서’는 두 번 이상 유의한 효과 크기가 있는 것으로 나타났다. 한 번도 유의한 효과 크기를 보이지 않는 것은 ‘접근 통제’, ‘지역 역량’, ‘지역 문화’인 것으로 나타났다. 따라서 보다 효율적인 CPTED전략을 실행하기 위해 본 연구결과에서 도출한 전략을 중심으로 실행할 필요가 있다. The purpose of this study was to contribute to the implementation of a more efficient CPTED strategy by measuring the Effect Size of the CPTED through meta-analysis of previous research results on the fear of crime. The results of this study are as follows. In terms of the effect size analysis, among the strategies and factors of CPTED, variables showing significant effects on the objective variable of crime damage and fear of crime decrease have positive effects such as ‘surveillance’, ‘maintenance’, ‘Social ties’, ‘activity support’, ‘territories’, ‘usability’, and ‘physical disorder and social disorder’ as negative effects. Especially, ‘surveillance’ and ‘maintenance’, ‘social and physical disorder’ showed significant Effect Sizes more than once. It was found that ‘access control’, ‘local competence’, ‘local culture’ were the least effective size.

The purpose of this study is to suggest a basic material in making deterrence policy of hit-and-run crashes. Analysing psychological factors that impact to the hit-and-run crashes of drivers will be the first step to prevent those crashes. However, previous studies are focused on the factors of road conditions, types of vehicles, characteristics of victims and drivers, not psychological factor. This study is focused on the psychological factor. For this study, 268 drivers-whose license were suspended for accidents, law violation or drinking driving offending- self-reported data were used. This study analysed the psychological factor to hit-and-run crash. For analysing, multiple regression analysis was conducted. The results are as follows. First, this study categorized the psychological factors as four factors, afraid of accident, probability of arrest, and hiding psychology, absence of surveillance. Second, results revealed that hiding psychology, absence of surveillance are significant factors to the hit-and-run psychology. The most powerful factor is hiding psychology. This study had a major limitation. First, data used this study were not targeted only an hit-and-run crashes experienced drivers. Second, the study area was constrained to only tow provinces, which put restraint on generalization of the study results. Nevertheless, this study made valuable contributions in establishing hit-and-run deterrence policy. Future study should takes this limitation into consideration.

음주운전죄 형량의 영향요인 유형화 및 영향정도 분석을 통한 음주운전 억제에 관한 연구

정철우(Jeong Cheol Woo),권기병(Kweon Ki Byiong) 경찰대학 경찰학연구편집위원회 2012 경찰학연구 Vol.12 No.3

This study quantified the general citizen or a drunk driver by raising his sentence shall be calculated in detail. And the purpose of this study was deterrence the DWI through the threat of sentencing. This study used data of the police enforcement on DWI in cooperation with Geumjeong Police Station, BMPA in 2006. Polices' Interrogation charged with DWI of send opinion was written based on the 2456 event. Also, the data of 625 criminal history of the suspects were analyzed. And this study performed multiple regression analysis to quantify for each factor impact on the sentencing. Results are as follows. First, illegal factor affects the sentence was greater than career factor. Second, the drunk driver's experience(previous criminal record for DWI, criminal record, traffic accident record) has a greater influence on the sentencing. Third, estimation of sentencing due to DWI compared with average monthly income can act as deterrence factor of DWI. Policy proposal for traffic safety, legal and administrative penalties have deterrence effects on traffic safety is at the core of policy effects. Even though it is limited to the enforcement of penalties, but by specific notice of the penalty is possible. If the citizens take advantage of the results of this study in a variety of ways, DWI determined to decline somewhat.

정철우 ( Jeong Cheolwoo ),이상엽 ( Lee Sangyeop ) 한국경찰법학회 2021 경찰법연구 Vol.19 No.3

This study calculated the weight on the probation criteria presented by the sentencing committee to be referred to when a judge is sentenced to probation for theft crimes, so that more objective and reasonable probation can be achieved. The criteria for probation presented by the sentencing committee divided positive (negative) categories into major reasons for consideration and general reasons for consideration, and this study also observed these categories. The weight was calculated by applying the AHP technique to the factors in each categories, and the research results are as follows. As a result of weighting, legal experts judged that it is reasonable to classify "no criminal record" classified as a major reason for consideration among positive reasons as a general reason for consideration, and "negative participation in crime" as a major reason for consideration. Experts judged that "same crime record" and "no recovery from damage" classified as major reasons for consideration among negative reasons should be classified as general reasons for consideration, "lead role of accomplices" and "attempt to conceal evidence" should be classified as major reasons for consideration. The case in which a actual sentenced and a case in which a suspended sentence calculated by applying weights were compared. Of the 23 cases, 7 were inconsistent, and at least 4 cases in which probation sentenced may have involved the judge's will, even though there were more negative factors in the sentence of probation. It is hoped that the results of this study will also be used as an empirical basis for the sentence of probation, and research should be conducted to rationalize the criteria for the sentence of probation with more sophisticated techniques in the future.

교통질서행정에서 인센티브 정책의 행정목적 달성효과 연구

정철우(Jeong Cheolwoo) 경찰대학 경찰학연구편집위원회 2016 경찰학연구 Vol.16 No.3

경찰 질서 행정에서의 패러다임의 전환이 필요한 시점에서 인간의 동기 부여적 측면에 착안한 인센티브 제공 방식이 널리 도입 될 필요가 있다는 주장이 제기된 가운데 경찰청에서 도로교통법 시행령을 개정하여 소위 ‘착한 마일리지’제도라는 인센티브 제도를 도입하였다. 본 연구는 이러한 인센티브 정책이 과연 의무이행 확보의 효과가 있는지에 대한 실증적인 검증을 통하여 인센티브 정책 도입의 확대에 논리적이며 실증적인 기초 자료를 제공할 목적으로 수행되었다. 서울의 4개 경찰서 관할에 거주하는 운전자들을 본 정책의 혜택에 신청한 집단과 신청하지 않은 집단으로 구분하여 그들의 운전 태도변화를 법규위반 비율이라는 기준으로 비교하였다. 포아송 및 음이항 회귀분석, 그리고 공분산 분석 방법을 이용하여 분석한 결과, 인센티브 제공정책인 ‘착한 마일리지’제도는 법규위반 비율을 감소시키는 효과가 나타나는 것으로 나타났다. The traditional methods of securing a performance of duties are based on the ‘forced administrative method’. But it was well known that their effectiveness had some limitations. So the another methods are introduced, for example, imposing the dues, supply rejection, public notification, employment restrictions. These new methods had the limitations, too. Nowadays, it is said that the paradigm of performance securing method should be changed and new paradigm method introduced. For example, the ‘incentive policy’ is most representative one. Three years ago, Korea National Police Agency introduced the ‘a good driving mileage’ as a incentive policy. If drivers promise not to violate the law and not to make traffic accident, and when they keep their promise for one year, Police Agency give them 10 point as a prize. It can compensate their penalty point that given when they violate traffic laws. For this study, data of two group, 42,881 drivers’ traffic behavior for two years were collected. One group asked ‘a good mileage’point, the other group did not. This study compared the violation ratio between the two groups. Negative binominal regression model and Covariance methods were conducted. The result of this study showed that the incentive policy is effective in reducing the violation ratio. This study suggest that lot’s of incentive policies should be introduced and developed in ‘Police Order Administration’ field.

The purpose of this study is to provide a basic materials in traffic safety policy making by analysing the effectiveness of traffic enforcement through driver`s attitude changing. Data of 296 drivers`s behavior and traffic accident records in the ten signalized intersections for 5 years were collected in Pusan Metropolitan since 2003. To analysing the effectiveness of police traffic enforcement through the driver`s attitude changing, analysis of covariance and logistic regression analysis were conducted. The results are as follows. First, there isn`t any effectiveness of traffic accident reduction of traffic enforcement. Comparing the adjusted means as a result of covariance analysis, average traffic accidents of the drivers with enforced experiences are more than those of unenforced. Second, comparing the odds ratio as a result of logistic regression analysis, the probabilities of drivers with enforced experiences are as 4.95 times high as those of unenforced. Third, both the results of covariance analysis and logistic regression are the same. Consequently, the attitudes of enforced drivers aren`t changed through the police traffic enforcement. So, some researchers suggest that the incentive measures rather than the regulatory ones, for example discounts of parking fare, amusement park fare, premium, are more effective in changing the driver`s attitude and in reducing traffic accident. Police Agency should consider these incentive measures into consideration to reduce traffic accidents. Also the periodic and well-organized traffic safety education will contribute to reducing traffic accidents.

교통사고 유발 범칙행위의 벌점 및 범칙금 분류 연구

정철우 ( Cheol Woo Jeong ),권기병 ( Ki Byeing Kweon ) 한국경찰법학회 2011 경찰법연구 Vol.9 No.2

The purpose of this study is to categorize penalty scores and fine based on a heavy dangerousness rate of traffic accidents. 137,995 traffic accidents data, with only one passenger in the vehicle, caused by 11 violation items during 2005-2009 were collected. They can be categorized to 3 penalty score groups and 5 fine groups followed in as current penalty rules through the K-Means cluster analysis method. The results were as follows. First, in penalty scores, 11violation items are categorized to 3 groups. Analysing result reveals that some items should be reclassified. Including signal violation, 7 items were up graded and using cell phone while driving was downgraded. In fine, including the passing the center line, 6 items were up graded, and using cell phone while driving was downgraded. Second, F test was conducted about the penalty score groups and fine groups respectively, there were significant differences between each groups. Third, a result of Spearman rank correlation analysis showed that there is very high correlations between penalty score groups and fine groups. As a whole, including the over speed(20-40km/h), 5 items were under estimated in the view of dangerousness, and using cell phones while driving is overestimated, so they should be assigned rationally than those of current. This study is expected to be a basic material to establish and to operate the traffic penalty score and fine policies.
