지자체 단위의 도로이동오염원 배출량을 보다 현실적으로 산정하기 위하여 배출량 산정 시 기초자료인 차량 등록대수를 보정하는 방안을 검토하였다. 국가교통DB를 이용하여 수도권 지역의 특정 차종(RV, 승합차, 버스, 화물차)에 대한 차량 등록대수를 보정한 결과, 지역별로는 서울의 오차율이 가장 크고 차종별로는 버스와 화물차의 오차율이 큰 것으로 나타났다. 또한, 배출량 산정에 영향을 미치는 기존 등록대수와 보정 등록대수 편차의 절대값은 수도권 지자체 모두 화물차가 가장 큰 것으로 나타났다. 배출량 산정 결과, 기존 등록대수 기반의 배출량과 보정 등록대수 기반의 배출량의 차이는 약 9%로 나타났으며, 수도권 지자체 중에서는 인천의 배출량 오차율이 가장 큰 것으로 나타났다.

Average concentration of PM in Seoul metropolitan area satisfied the Korean air quality standard in 2010. Furthermore, concentration of PM in all boroughs across Seoul met the air environment standard in 2012. $PM_{10}$ concentration was relatively higher in center of Seoul in comparison to the rest, while $PM_{2.5}$ concentration showed exactly the contrary result. We analyzed the effect that PM emissions from vehicles would have on PM concentrations across Seoul. The results showed that average annual PM concentration recently decreased in Seoul although the number of vehicles registered annually continued its upward trend. By contrast, average fine dust concentrations in Seoul showed a decline which suggested that correlation between annual average PM concentrations and number of registered vehicles remained low. However, year-on-year vehicle registration rate recently showed a declining tendency in the same way as the trend of changes in average PM concentrations. Particularly, the upward trend in annual average PM concentrations in 2002 and 2007 was consistent with the increase in vehicle registration rate, suggesting that vehicle registration rate was closely associated with changes in PM concentrations.

The fatalities rate for passenger vehicles, vans, and commercial vehicles is 1.23, 1.90 and 2.46 deaths per 10,000 registered vehicles, respectively. This shows that vans and commercial vehicles are vulnerable compare to passenger vehicles. To evaluate the crashworthiness of van and Light Truck Vehicle(LTV), we carried out frontal offset crash test at 64km/h, 40% overlap as per IIHS(Insurance Institute for Highway Safety). The test result show that LTV is very poor to protect occupant at frontal crash cause there is no safety system such as airbag and pretensioner and front end length(distance from front bumper to steering wheel) is short. One of the van rated as the lowest rating even it is equipped with airbag, cause its safety cage was collapsed during the test. This result shows that the structural integrity is very important in terms of occupant protection.

The Korean Auto industry has developed remarkably over the past 30 years. In 2000 alone, Korea produced 3.11 million vehicles, and the number of vehicles registered surpassed the ten million mark. As the number of vehicles registered in Korea has increased, yew after you, a rising number of cars have been scrapped. In 2000, a total of 455,592 automobiles were scrapped, up dramatically from only 101,158 in 1989. The system for handling of ELV(End-of-Life Vehicles) in Korea is governed by the "Motor Vehicle Control Act". The Act places the responsibility for vehicle scrapping directly on the vehicle owners. h vehicle owner can only can eel a vehicle registration after he gets a certificate from an authorized vehicle dismantler showing that his vehicle was properly scrapped according to the law. The take-back rate of ELV reaches nearly 100% in Korea. The vehicle scrapping process in Korea is very similar to those in other countries. fluids such as fuels and oils are first removed, and recyclable parts are collected and separated. Engines and transmissions are dismantled and recycled for use as raw material. Plastics, which are not easily reused, are generally treated as industrial wastes. The "Motor Vehicle Control Act" prohibits reuse of certain parts in order to guarantee the safety of the used auto parts. However, some restrictions on the reuse of auto parts have recently been eased to promote recycling. In this paper, additionally, car recycling policy of the foreign countries such as Japan, Germany and EU were reviewed.

In the last year, the number of registered vehicles in Korea surpassed the 15 million mark, and increase in number continuously. Nowdays, this tendency has raised some problems inevitably in the view of expansion of ELV(End of Life Vehicles) and earth environment pollution resulted from it. A foreign country is strengthening law about a car recycling for to solve this problem. Car recycling technology in Japan was introduced in this paper.

Eco-friendly policies proposed by the government of The Republic of Korea have encouraged the use of eco-friendly vehicles. Hydrogen vehicles have exhibited the highest growth rate, although the current number of registered vehicles is low. In hydrogen vehicles, a thermally activated pressure relief device (TPRD) is installed to prevent explosions in the hydrogen gas cylinder. When discharged due to low ignition energy, hydrogen gas readily forms a jet flame. The risks induced by such jet flames were analyzed through a numerical analysis. Jet flames can activate TPRDs installed in nearby hydrogen gas cylinders. As a result, high-voltage cables exposed in the lower area of a vehicle can ignite within seconds. There was a 9.5-kW/m2 area around the vehicle (which can result in casualties) at a distance of ~5 m from the hydrogen gas cylinder, and a 37.5-kW/m2 area (which can cause significant damage) in the form of an inverted triangle toward the lower section of the vehicle. We believe that the risk factors analyzed herein should be considered for addressing accidents in hydrogen vehicles.

In this paper, we present a dynamic matching methodology for the logistics brokerage agent that intermediates empty vehicles and freights registered to the logistics e-marketplace by car owners and shippers. In this matching methodology, two types of decisions should be made: one is when to match freights and vehicles and the other is how to match freights and vehicles at that time. We propose three strategies for deciding when to match, i.e. real time matching (RTM), periodic matching (PM), and fixed matching (FM) and use Hungarian method for solving tho how-to-match problem. In order to compare the performance of the when-to-match strategies, computational experiments are done and the results show that the waiting-and matching strategies, PM and FM, give better performance than real time matching strategy, RTM. We can expect that the suggested matching methodology may be used as an efficient and affective tool for the brokerage agent in the logistics e-marketplaces

In the FY 2003, the number of registered vehicles in Korea reached 14 million, which is 7.7% increase from the previous year. The increase of number of vehicles has caused a lot of social problem with enormous costs. The social costs related to the vehicles includes environmental costs resulting from pollution and scraping of vehicles, those resulting from life-saving and repairing from car accidents and so on. There have been m any efforts to reduce the social costs in m any areas. As a part of the efforts, there are recent grow ing interests on the damageability & repairability in related industries. In this study, we investigated the cases of two different types of bum per stay. Futhermore, we analyzed their effects on damageability & repairability and reduction of repair cost. So we found that if the manufacturers design new cars with good damageability & repairability, then the total repair cost in crash will be reduced.

우리나라에서 한 해 교통사고로 사망하는 인원은 2004년 현재 6,563명에 이르고 있으며 자동차 1만대당 사망자수는 3.99명으로 미국의 1.85, 일본의 1.10, 영국의 1.14, 독일의 1.23명보다 월등하게 높다. 이 연구는 높은 교통사고 발생률 및 사망률을 보이는 우리나라의 최근 현황을 분석한 경찰청의 통계자료를 주로 활용하였다. 우리나라의 자동차 증가추이를 보면 1997년 천만 대를 돌파했고 1998년 IMF의 영향으로 잠시 주춤했던 자동차 증가추세가 경기 회복이 시작된 1999년 이후 연 평균 86만 대씩 증가세를 보이고 있다. 우리나라 자동차는 2004년 말 현재 1,400만 대를 넘었으며 차량에 의한 과속 등 교통법규 위반과 이로 인한 각종 사고, 차량이용 범죄 및 도난차량 증가 등의 문제는 중요한 사회문제로 부각되고 있다. 여기에서는 경찰이 수집한 교통사고 현황 가운데 몇 가지 중심이 되는 특징을 분석하여 교통안전성확보를 위한 경찰활동을 제언하고자 한다.
