PURPOSES: According to accident statistics for road built in 2004, the ratio of accidents on frozen roads to normal roads is 0.9%, whereas the fatality ratio is 2.7%. The risk of accidents on frozen roads is very high. Measures taken every year to prevent traffic accidents of frozen roads in the winter season are still insufficient. Additionally, measures have been established mainly on rural roads. Therefore, for urban roads, analyses and measures to prevent accidents are lacking. In this study, data on accidents on frozen roads was used to search for the causes behind these accidents and measures to reduce accidents have been recommended. METHODS: In this study, collected data from the TAMS (Traffic Accident Management System), which were collected by the Seoul National Police Agency was used. The data were divided into vehicle, people, and condition of road. The analytical model used here was the Logistic Regression Model, which is frequently used for traffic safety and accident analysis. This study uses the odds ratio analysis to search for variables related to frozen road traffic accidents in each category. A total of 18 out of 47 variables were found to be the causes of accidents. RESULTS: From the results of the comparative analysis of 18 variables, the category of the condition of the road was found to be the most critical. Contrary to expectations, more accidents occurred in clear weather than in other conditions. Accidents on bridges occurred frequently, and its odds ratio was the highest compared with other road types. When BPT is operated, the probability of accidents on frozen roads is lower than in general conditions, and accidents occurred frequently on roads with less than four lanes. CONCLUSIONS : Based on the results of this study, suggestions for reducing the risk of future domestic road accidents in freezing conditions are indicated as follows. First, it is necessary to perform a technical review of the urban road traffic accidents caused by frozen roads. Second, it is necessary to establish criteria for the study of the road environment based on the major causes of road accidents on frozen roads. Third, improvements in urban road environmental factors should be made.

도로불편민원 데이터 기반 도로 낙하물 발생 유형 분석

김진국,전우훈 차세대컨버전스정보서비스학회 2023 디지털예술공학멀티미디어논문지 Vol.10 No.4

Despite the government's efforts to crack down on cargo trucks, traffic accidents caused by road drops continue to be repeated every year. It is very important to prevent road maintenance because the fatality rate of road drop accidents varies depending on the type of drop object, but it is about 28%, twice as high as the fatality rate of all traffic accidents. The purpose of this study is to lay the basis for basic data for establishing road maintenance policies by analyzing the types of road debris that mainly occur on the road based on road inconvenience complaint data. As a result of analyzing civil complaint data related to road drops from 2014 to 2022, three key topics were derived: the location of the road debris, animal carcasses (cat, roadkill, elk, etc.), and road driving risk factors (rocks, garbage, soil, traffic accident debris, etc.). Since traffic accidents caused by road drops are highly likely to lead to large accidents, rapid processing is essential in the event of road debris. It is necessary to prepare measures to prevent this in advance through education for business vehicle drivers, crackdown on cargo truck loading defects, and continuous real-time monitoring. Through these active efforts, it will be possible to secure efficient road maintenance and traffic safety. 정부의 화물차 등 적재불량 단속의 노력에도 불구하고 도로 낙하물로 인한 교통사고는 매년 지속적으로 반복되고 있다. 도로 낙하물 사고의 치사율은 낙하물의 종류에 따라 상이하지만 약 28%로 전체 교통사고 치사율에 비해 2배나 높기 때문에 도로 유지관리 측면에서 이를 예방하는 것은 매우 중요하다. 본 연구의 목적은 도로불편민원 신고 데이터를 기반으로 도로 상에서 주로 발생하는 낙하물의 유형 분석을 통해 도로 유지관리 정책 수립을 위한 기초자료의 근거를 마련하는 데 있다. 2014년부터 2022년까지 도로 낙하물과 관련된 민원 데이터를 분석한 결과, 낙하물 발생 위치, 동물사체(고양이, 로드킬, 고라니 등), 도로주행 위험요인(낙석, 쓰레기, 토사, 교통사고 잔해 등)과 같이 3개의 주요 핵심 토픽이 도출되었다. 도로 낙하물로 인한 교통사고는 대형사고로 이어질 확률이 매우 크기 때문에 낙하물 발생시 빠른 처리가 필수적이다. 사업용 차량 운전자 대상 교육과, 화물차 적재불량 단속, 그리고 지속적인 실시간 모니터링을 통해 이를 사전에 예방할 수 있는 대책 마련이 필요하다. 이러한 적극적인 노력을 통해 효율적인 도로 유지관리업무 및 교통안전 확보가 가능할 것이다.

The Mapping for Relationship between Road Accidents and Traffic Congestion for Expressway Management Decision

S. Sarifah Radiah Shariff,A. Dinnul Firdausi Mohamad Ibrahim KINFORMS 2020 Management Review Vol.15 No.1

Traffic congestion and road accidents are part of the major transportation problems across the globe. In a developing country like Malaysia, traffic congestion and road accidents are among serious problem that have impacted many sectors namely economic and social sectors. In this study, the relation between traffic congestion and road accidents is explored based on data collected from main expressway in Klang Valley. The objective of this study is to identify the locational pattern between traffic congestion and road accidents (if there is) as well as to propose method of data collection that provides the information. Descriptive analysis and Single Factor ANOVA are used to explore and analyse the primary data set of traffic congestion and the secondary data set on road accidents obtained from the selected Expressway. It is found that heavy traffic congestion occurs the most especially during morning peak hours on weekdays. However, road accident happens randomly at various location and time. From the mapping and test done, it shows there is no significant relation between traffic congestion and road accidents, yet some locations are prone to both traffic congestion and road accidents.

Dynamic behaviour of high-sided road vehicles subject to a sudden crosswind gust

Xu, Y.L.,Guo, W.H. Techno-Press 2003 Wind and Structures, An International Journal (WAS Vol.6 No.5

High-sided road vehicles are susceptible to a sharp-edged crosswind gust, which may cause vehicle accidents such as overturning, excessive sideslip, or exaggerated rotation. This paper thus investigates the dynamic behaviour and possible accidents of high-sided road vehicles entering a sharp-edged crosswind gust with road surface roughness and vehicle suspension included. The high-sided road vehicle is modelled as a combination of several rigid bodies connected by a series of springs and dampers in both vertical and lateral directions. The random roughness of road surface is generated from power spectral density functions for various road conditions. The empirical formulae derived from wind tunnel test results are employed to determine aerodynamic forces and moments acting on the vehicle. After the governing equations of motion are established, an extensive computation work is performed to examine the effects of road surface roughness and vehicle suspension on the dynamic behaviour and vehicle accidents. It is demonstrated that for the high-sided road vehicle and wind forces specified in the computation, the accident vehicle speed of the road vehicle running on the road of average condition is relatively smaller than that running on the road of very good condition for a given crosswind gust. The vehicle suspension system should be taken into consideration, and the accident vehicle speed becomes smaller if the vehicle suspension system has softer springs and lighter dampers.

도로교통법에 나타난 교통사고 발생시 조치의무에 관한 고찰 -도로교통법 제50조 제1항을 중심으로-

정광정 ( Gwang Jeong Jeong ) 청주대학교 법학연구소 2005 法學論集 Vol.25 No.-

This paper treats Clause 1 Article 50 of Road Traffic Act prescribing the measures when a traffic accident occurs. The measures at a traffic accident refer to those for minimizing the damages on human life, body and properties when a traffic accident occurs. Since the implementation of this obligation is closely related to the life of the victim, they prescribe severe punition if this obligation is not implemented. Then, what is the traffic accident to which such measures must be applied? For this, this paper constructs the concepts by bringing up a question and regarding each respective provision. And it classifies into the stages such as stopping car and measures for injury relief in order to specify the scope of the measures obligation in a traffic accident. Then it treats the legal limitations of the obligation of injury rescue measures. Since there is not a provision about how they should do such injury rescue measures, they depend on the judicial precedent that such measures shall be taken as much as they are required by a sound consciousness in consideration of the accident situation including accident details and degree of damage. To improve these problems, it is necessary to ① establish the injury rescue measures on site in order to permit taking appropriate measures where they are needed, ② expand the scope because it has a problem that if the scope of such obligation as the injury rescue measures is applied only to the road, it could not be applicable to an accident happening in a place that is not included in the definition of the road, ③ clearly prescribe the concept because some argue that the concept about the injury protection measures at a traffic accident is limited only to an accident occurring on a public road under Article 5-3 of Traffic Accident Disposition Exemption Act and Specific Crimes Aggravated Penalty Act, and finally ④ expand the scope of punition because the penalties under the Road Traffic Act cannot be applicable if someone incurs a traffic accident provoking property damages and runs away on a place that is not the road, by reason that the place cannot be included in the legal definition of the road. To conclude, it is required to reinforce the injury rescue function by improving the problems in the measures obligation at a traffic accident and to legislate in the way not to make unreasonable damages even to the driver who incurred a traffic accident.

결빙구간의 교통사고 심각도 영향 요인 연구

이상준 한국안전학회 2017 한국안전학회지 Vol.32 No.6

A frozen road surface increases traffic accidents during the winter season. Hence, information on easily-frozen road sections and their specificities are required to prevent traffic accidents. Frozen road surfaces are determined by equipment measuring road surface temperatures. However, there are limitations in investigating the entire road network. Therefore, it is imperative to develop new methods that effectively determine road surface freezing risks. Meteorologically, road surfaces are frozen when the actual temperature cools down to the dew point temperature. Under this condition, there is likely to be frost if relative humidity reaches 100% and frozen road surfaces as the temperature gets lower. Meteorological characteristics give us an alternative to a direct measurement road surface temperature to estimate risks of road surface freezing. Based on the clues, the relationship between severity of traffic accidents and temperature changes is empirically investigated using Paju weather data. The results reveal that as the temperature gets lower and changes in current temperature are relatively small, the severity of traffic accidents become higher. In addition, the same is true when the difference between current temperature and the dew point temperature is relatively small, as it increases possibilities of road surface freezing. Future studies must investigate how current temperature and the dew point temperature affect road surface freezing and thereby establish a time-space scope to estimate possible road surface freezing sections using only weather and road material type data. This would provide invaluable information for predicting and preventing frozen road accidents based on weather patterns.

산악관광도로 위험구간의 교통사고 요인분석 및 감소방안

오재환(Oh, Jae-Hwan),황경수(Hwang, Kyung-Soo),김경범(Kim, Kyung-Bum),양정철(Yang, Jeong-Cheol) 한국산학기술학회 2016 한국산학기술학회논문지 Vol.17 No.1

본 제주도 산악관광도로를 대표하는 교통사고가 잦은 지방도 1100도로, 516도로, 비자림로를 중심으로 교통사고를 유형별로 구분하여 사고특성을 분석하고, 통행 AHP 분석을 통해 주요 사고요인을 분석하고 지점속도의 분포와 교통사고에 영향을 미치는 요인들을 비교 분석하였다. 도로특성상 관광객이 통행이 많고, 렌트카의 혼합율이 1100도로 및 비자림로는 36.70%∼71.60%로 분석되었으며, 현재 조사 대상 지방도는 60km/h의 제한속도로 규제하고 있으나, 도로선형 및 기후, 경관 등의 운전자 시거를 고려할 경우 제한속도를 40km/h로 규제할 필요성이 있으며, 조사대상 지방도의 40km/h이상 과속비율이 516도로는 87.0%, 1100도로는 88.57%, 비자 림로는 93.1%로 분석되어 과속의 비율이 높은 것으로 분석되었으며, 과속에 따른 사고위험에 노출되어 있는 것으로 분석되 었다. 516도로, 1100도로, 비자림로의 과속비율이 87.0%∼93.1%로 무인과속단속시스템은 한 지점의 속도만으로 과속을 단속하는 시스템으로 단속지점에서만 속도를 줄이는 캥거루효과가 발생하고 있어 연속적인 속도감소 효과를 기대할 수 없다. 따라서 제주도의 도로특성상 연속적인 위험이 존재하는 도로구간에서는 교통사고 예방을 위해서는 위험구간의 평균속도로 과속차 량을 단속하는 무인구간속도 위반단속시스템 도입이 필요하다. In Jeju-Do, there is the 1100 Road, 516 Road, and Bijarimro, which are typical mountain sight-seeing roads in Jeju. These roads are local roads that have been the location for many traffic accidents. This study focused on these roads, categorized the type of traffic accident and analyzed the accident characteristics. The major accident factors were analyzed through trip AHP analysis, Comparative analysis of the velocity distribution and the factors affecting traffic accidents were analyzed. Tourists took many trips on these roads. The mixing rate of the rental cars was 36.70%~71.60% in 1100 road and Bijarimro. Currently, these local roads are regulated by a speed limit of 60km/h. However, it might be necessary to reduce the speed limit to 40km/h considering the geometric line form of the road and the climate in these areas. The speed limit of more than 40km/h is found 87.0% on 516 Roads, 88.57% on 1100 roads, and 93.1% on Bjarimro, In these roads, the speed ratio is higher as described above. Therefore, these roads have been found to have a higher risk of traffic accidents by overspeeding driving. The overspeed driving ratio of these roads was 87.0%~93.1%, The overspeed driving enforcement method at one spot has only the effect of reducing the speed at that enforcement place; the effect cannot be expected for the other places or sections. It is necessary to introduce a section overspeed driving enforcement system utilizing the average velocity in these areas to prevent traffic accidents.

생활도로에서의 교통행태와 교통사고특성에 관한 연구 - 서울특별시를 중심으로

이수일,임준범,최종철,주성갑 대한토목학회 2016 대한토목학회논문집 Vol.36 No.1

In Korea, the number of crash accident victims per 100,000 population is three times higher than the average of OECD. In particular, 60% of it occurs on the community road. Thus, this study intends to analyze the causes of such accidents through a pedestrian and vehicle traffic survey. The purpose is to establish practical safety enhancement measures for community roads. In recent years, lots of changes have occurred in the pedestrian environment. A traffic survey shows that 65% of pedestrians walk on the right and 17% of people use smart-phones while walking. An eye camera experiment shows that the operation load of drivers on the community roads is more than 4 times higher than those in urban roads. According to a speed survey, 62% of vehicles drive at 30km/h or above. The characteristics of accidents on community roads are as follows. First, the ratio of accidents on the edge of the road is 2.3 times as high as those on other roads. Second, when people walk on the right, the ratio of accidents is 2.5 times as high as that of walking on the left. Third, it becomes more dangerous when people cross the road from the right to the left. The majority of accidents is caused by unsafe driving (84.4%). When a vehicle makes a left turn, the likelihood of accidents is 2.3 times as high as those caused by a right turn. The ratio of accidents caused by vehicles going backwards is 14% among all accidents. In community roads, the focus of drivers should be at least 4 times higher than those on urban roads. Thus, walking in the opposite direction of vehicles and careless behaviors are highly likely lead to accidents. 우리나라의 인구 10만명당 차대사람 사망자 수는 OECD평균보다 약 3배 높고, 특히 생활도로에서 60% 이상 발생하고 있다. 따라서 본 연구에서는 보행자 및 차량의 통행실태 조사를 통해 사고원인을 분석하여 생활도로의 실질적인 안전성 증진방안을 도출하고자 하였다. 최근 보행환경은 우측보행 비율이 증가하고, 보행 중 스마트폰 사용자가 증가하는 등 많은 변화가 일어나고 있다. 통행실태 조사결과, 우측보행이 65%로 높고, 보행중 스마트폰 사용율도 17%로 나타났다. Eye Camera 실험을 통한 운전자의 운전부하량은 생활도로가 도시부 도로에 비해 4배 이상 높게 나타났으며, 속도조사 결과 30km/h이상 주행하는 차량이 62%로 높게 나타났다. 생활도로의 사고특성은 가장자리 통행사고 비율이 전체도로 대비 2.3배 높으며, 우측보행 시 사고가 좌측보행 시에 비해 2.5배 더 많고 우측에서 좌측으로 횡단할 때 더 위험한 것으로 분석되었다. 사고원인은 대부분 안전운전불이행(84.4%)이고, 차량이 좌회전할 때 사고가 우회전대비 2.3배 높고 후진사고의 비율이 14%로 높게 나타났다. 생활도로에서는 운전자가 일반도로에 비해 4배 이상 많은 운전집중력을 가져야하기 때문에 차량을 등지고 보행하거나 부주의한 행동을 하는 것은 사고로 이어질 개연성이 큰 것으로 분석되었다.
