본 연구는 교통안전공단과 사단법인 녹색교통운동이 공동으로 개발한 교통문화지수와 관련한 2002년과 2003년의 전국 81개 도시 자료를 토대로 통계적 분석을 행하여 이틀 대상도시들을 유형화하고 집단별 영향요언에 근거하여 교통사고 예방대책들을 제시하고자 하였다. 먼저 교통문화지수와 영향요인들에 대한 주성분분석 결과로는 4개의 주성분으로 구분 지을 수 있었으며,도시 특성별 최적 집단 수는 4개가 적합한 것으로 나타났다. 또한 이들 유형화된 집단별 교통문화지수에의 영향요인을 단계별 다중 회귀분석법을 이용하여 분석한 결과, 4개 집단 모두 높은 설명력을 갖는 회귀모형을 구축할 수 있었다. 이에 따라 각 집단별 교통사고 예방대책들을 구체적으로 제시할 수 있었으며, 아울러 투자된 시설이 얼마나 교통사고 예방에 효과적이었는가를 분석할 필요성이 있음을 향후의 연구 과제로 제시하였다. This study suggests strategies to prevent traffic accidents by utilizing impact factors per each cluster and the typical patterns of 81 cities based on the statistical analysis of the data concerning the TCl which was developed from the partnership of the Traffic Safety Authority and the Green Traffic Movement Corporation in 2002 and 2003. The Principal Component Analysis and Cluster Analysis on impact factors and Tel result in 4 components and 4 clusters. Also as the results of Stepwise Multiple Regression Analysis examining the relationship between impact factors and TCl, R2 values of these models show high to all clusters. According to the results, we suggest strategies to prevent traffic accidents per cluster concretely and it is necessary to analyze how effective the invested facilities are in reducing traffic accidents in the future.

This study examined the effect of police officer’s perceived organization justice to affective commitment. A factor analysis was carried out and a survey with 303 police officers was conducted to test hypotheses. The results showed that police organization justice was consisted of three components, distributive justice, procedural justice, and interactional justice. Multiple regression analysis showed that all three components of organizational justice had a positive effect on affective commitment. Among three components, interactional justice had the strongest effect. Results of this study were partly consistent with those of McFarlin & Sweeney(1992), Lim & Yoon(1998), and Park & Kim(2003)’s studies. Policy implications of these findings were discussed in detail.

정철우(Jeong Cheol Woo),최정호(Choi Jung Ho) 경찰대학 경찰학연구편집위원회 2012 경찰학연구 Vol.12 No.4

The purpose of this study was to provide basic materials for traffic safety policy by analysing the effectiveness of raising punishment severity to traffic law abidance. Data of 2205 drivers' behavior for 8 years, who have traffic law violation records were collected in Yong-In City, Gyongi province since 2003. For the analysis, a data mining method(CART) and Analysis of Covariance method were conducted. The results of this study were as follows. First, the result of CART analysis, the severity of punishment was a very important factor to the driver's traffic law violation. It is the first factor to the driver's violating traffic law than other factors. Second, the result of Analysis of Covariance shows that severer punishment sentenced drivers violated less than those of slighter sentenced. And it's effectiveness lasted for 8 years. The results of both CART analysis and Analysis of Covariance showed that a severer punishment to the traffic law violating drivers can reduce the violation traffic law. This study had two major limitations. First, socioeconomic variables such as education level, marriage status, and economic condition were not controlled. Second, the study area was constrained to only one city, which put restraint on generalization of the study results. Nevertheless, this study made valuable contributions in that the long-term and objective effect of raising punishment severity was proved using CART analysis and Analysis of Covariance.

정철우(Jeong Cheol Woo),조은순(Jo Eun Soon) 경찰대학 경찰학연구편집위원회 2011 경찰학연구 Vol.11 No.2

The purpose of this study is to provide a basic materials in traffic safety policy making by analysing the effectiveness of traffic safety education. Data of 10,000 drivers's(5,000 drivers were educated and 5,000 were uneducated when they got the driver license, respectively) behavior and traffic accident records for 7 years were collected since 2003. To analysing the effectiveness of traffic safety education, analysis of covariance and logistic regression analysis were conducted. The results are as follows. First, there is effectiveness of traffic safety education in reducing traffic accident. Comparing the adjusted means as a result of covariance analysis, average traffic accidents of the educated drivers are more than those of uneducated. Second, comparing the odds ratio as a result of logistic regression analysis, the probabilities of traffic accident in uneducated drivers are 23.4% higher than those of educated. Third, both the results of covariance analysis and logistic regression are the same. Consequently, traffic safety educations to the first driving license acquisitors should be expanded.

고속도로 교통사고 주 원인의 영향요인에 관한 연구

정철우(Jeong Cheol Woo) 경찰대학 경찰학연구편집위원회 2007 경찰학연구 Vol.7 No.1

This study suggests the strategies to research the impactive factors about the major causes in freeway accidents by using binominal logistic regression analysis. The major causes are derived from Spearman's rank correlation coefficient: those are nap driving and over speed driving. To quantify the human, road, and environmental attributes which impact nap driving and over speed driving, we can developed the logistic regression model that classify better than that of basics. The 6th variables, the time of day, the distance of origin, weather condition, ages, horizontal line type, and vertical line type, are statistically significant to the nap and over speed driving. According to the result, we can fine the fact that the probability of nap driving are high at the nighttime, in long driving distance, at Friday, in the fine weather, in the left curve and sag sections, non-work zone and in female, aged drivers, and the probability of over speed driving are high in the weekday afternoon, adversed weather conditions, in the right curve with a turning radius below 500m sections, at the climbing grade over 3% sections, in the work zone and female, aged drivers. The result may used to develop the education program for the drivers causing accidents and to decide the criterion of premium insurance rates. It may also used to establish the standards of freeway design and that of law enforcement agencies activity.

집회시위의 비용 추산에 대한 연구

정철우(Jeong, Cheol Woo),김학경(Kim, Hak Kyong) 경찰대학 경찰학연구편집위원회 2015 경찰학연구 Vol.15 No.3

본 연구는 서울에서 집회시위가 많은 지역을 선정하여 집회시위에 따른 교통상 피해비용을 산출함으로써 집회 시위 주최 측에게 국민 피해의 최소화를 위한 시위문화의 정착을 유도하기 위할 목적으로 수행되었다. 교통량의 변화가 안정을 보이는 평일인 화, 목요일의 14:00-15:00에 도로를 점거하고 행진하는 경우를 가정하여 비용을 추산하였다. 그 결과 집회 시위가 없을 경우 서비스 수준이 C였으나 도로를 점거함으로써 서비스 수준이 급격히 나빠졌으며, 3차로 차단 진행시 시간 당 최대 960만원 정도의피해비용이 발생하는 것으로 추산되었다. 집회 시위 주최 측과 경찰은 서로 합의를 통하여 집회의 자유를 보장하면서도 국민 피해가 최소화할 수 있는 건전한 시위문화 정착에 노력해야 할 것이다. The research is basically geared toward measuring the economic costs of traffic congestions caused by public protest marches in Korea. The Republic of Korea Constitution explicitly provides for the right of the people peaceably to assemble and associate. In other words, the freedom of assembly and association is a constitutional right in Korea, and hence, the Korean National Police should fully protect the freedom of public protests as well. Nevertheless, many opinion polls and studies show that when it comes to public protests, the most serious inconvenience of the general public is a traffic congestion, especially caused by occupation of roads by protesters. Therefore, there is a dilemma that the police should not only protect the freedom of public protests, but also minimize the people’s inconvenience- i.e. paralysed traffic from the perspective of the maintenance of public security. For accomplishing these two conflicting duties, the police need to negotiate with the protesters about the issues in question with the strategy of Negotiated Management Model in a proactive fashion. 29) In this context, the study specifically explores how protest marches influences urban traffic congestions, and further, how much the congestions impose economic costs within the Sungnyemun area in Seoul, where public protest and protest marches most frequently occurs and so, traffic is most seriously affected. Particularly, the research tries to financially gauge the traffic economic costs by employing a traffic flow simulation software program. The rationale for this research is that the protesters can justify their causes of protests by showing the general people that they clearly recognize their inconvenience with a view of traffic costs and so tries to take some diversion, when there is a high risk of serious traffic congestions. Finally, it is anticipated that the findings(measured traffic costs) can contributing to balancing the freedom of public protests against the maintenance of public security in Korea.

본 연구의 목적은 CPTED 구성요소가 범죄 예방 또는 범죄 두려움 감소에 미치는 중요성을 전문가 집단의 의견을 대상으로 분석함으로써 CPTED 전략에 대한 기초적 자료를 제시하는 것이다. CPTED 구성요소는 접근 통제, 감시, 강화로 구분하고 모두 36개 요소의 중요성을 쌍대비교하여 가중치를 산정하였다. 본 연구를 수행하기 위하여 범죄학, 경찰행정학, 경찰전문가 29명에게 설문하였다. 분석방법은 AHP 기법이 이용되었다. 연구결과, 주민들끼리의 유대 강화가 가장 중요한 요소였고, 다음으로 감시, 접근 통제의 순서로 나타났다. 또한 인적 자원 중심의 CPTED 전략보다는 기계와 장비에 의한 접근이 더 효과가 클 것으로 나타났다. 전문가들은 단기적 효과보다 장기적 효과를 고려한 의견이므로 CPTED 전략에 보다 효과적일 것으로 생각한다. The purpose of this study is to suggest a basic material to building the CPTED strategies through analysing expert’s opinion on CPTED element’s importance to the reducing crime and fear of crime. This study categorised the CPTED elements as 4 groups; access control, surveillance, and bonding. And this study compared 36 elements of CPTED by pair-wise. For this study, the AHP(Analytic Hierarchy Process) method was conducted. The results of this study were as follows. First, the most important element of CPTED to the reducing the crime and fear of crime is establishing the friendship between residents. The nexts are surveillance, access control. And it is expected that the CPTED strategy is more effective based on the mechanical elements than human resources.

정철우(Cheol-Woo Jeong),이종화(Chong-Wha Lee) 한국셉테드학회 2017 한국셉테드학회지 Vol.8 No.1

The purpose of this study is to suggest a basic material to establish the Park CPTED strategies aimed reducing crime and fear of crime through Need Analysis method in the views of users. For this study, the three steps required in the Need Analysis, t-test, Borich’s degree of need, and the Lotus for Focus were conducted. Data of 424 users of four urban park in Budang-Gyeongi do were collected. The results of this study were as follows. First, the four elements of Spacial Park CPTED strategy- lighting in the night, entrance control to the park, setting CCTV, regular patrol- were set priority. Second, the three elements of Facility Park CPTED stategy- facilities for anti tramp, CCTV at the bathroom, emergency call-were selected in priority. 본 연구는 공원 CPTED에 대한 연구의 지평을 넓히며, CPTED 전략별 요소에 대한 우선순위를 선정함에 있어 공원을 이용하고 있는 수요자 입장을 고려하여야 한다는 관점에서 수행되었다. 경기도 분당의 네 개 도심 자연공원을 이용하는 시민들을 대상으로 현재 공원 CPTED의 수준과 향후 필요로 하는 바람직한 수준에 대한 요구분석을 통하여 CPTED 전략의 우선순위를 분석 하였다. 본 연구를 수행하기 위하여 요구분석의 세 단계, t 검정, Borich의 요구분석, Borich 요구분석과 the Locus for Focus모델을 이용한 우선순위 선정이라는 과정을 거쳤다. 본 연구의 결과는 다음과 같다. 첫째, 공간별 CPTED 전략 가운데에서는 ‘야간 근린공원 조명과 적정 간격 배치’, ‘공원 안으로 진입 통제’, ‘방범시설(CCTV) 설치’, ‘정기적인 순찰, 방범 활동’이 가장 우선적으로 고려해야 할 요소로 나타났다. 둘째, 시설별 CPTED 전략 가운데에서는 ‘부랑자에 대한 조치’, ‘화장실, 휴게소등 휴식영역에 CCTV, 비상벨 등 안전장치’, ‘비상벨, 비상전화, 인터폰 설치’ 가 가장 우선적으로 고려해야 할 요소인 것으로 나타났다. 셋째, Borich 요구 도와 the Locus for Focus가 일치하지 않은 요소에 대하여 공원 이용자들은 부차적으로 고려해야할 요소로 생각하고 있는 것으로 나타났다. 따라서, 공원 이용자를 위하여 공원 CPTED 전략이 지향해야 하는 점은 기존의 자연적 감시라고 하는 공급자 위주의 전략과는 달라야 한다는 것을 나타내고 있다.

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.
