화물자동차의 과당경쟁 및 다단계 운송거래와 같은 화물운송시장의 구조적 문제로 인하여 화물자동차운임은 경유가격 인상 및 운송원가상승 요인으로 운임이 인상되더라도 최종 화물차주에게 까지 적절하게 반영되지 못하는 운임 왜곡현상이 발생하고 있다. 2017년 신정부에서는 "표준운임제"를 토대로 사업용 화물자동차가 과적, 과속 및 과로를 하지 않도록 최소한의 운임을 보장하기 위하여, 운송품목에 대한 원가를 도출한 후 적정이윤을 추가하여 운임을 공표하고 이를 위반하면 행정처분을 하는 "화물자동차 안전운송 운임제"를 도입하게 되었다. 그러나, 본 제도의 도입에 대한 이슈 및 컨테이너운임에 대한 영향에 대한 사전 분석이 필요하다. 따라서 본 연구에서는 "화물자동차 안전운송 운임제"가 도입될 경우 형성되는 운임제도에 관한 이슈와 이에 대한 대책을 분석하고 "화물자동차 안전운송 운임제"의 적용대상인 컨테이너운임에 미치는 지출비용의 영향요인을 분석하여 관련 정보와 시사점을 제시하고자 한다.

Rear collisions to expressway work trucks result many casualties these days. But, currently, no special measure are being taken except deploying sign trucks behind the working trucks. In the U.S and Europe, trucks with TMA(Truck Mounted Attenuator) are being deployed behind the working truck, which is regarded as the standard method for work area safety, thereby reducing the fatality rates and property damage tremendously. Also, standard for the performance of TMA are established and TMA can be used in the field only when it satisfies the standard. In Korea, neither the standard for nor any guide to the TMA exists. In the situation some manufacturer developed TMA without proper performance evaluation and marketed limited number of TMAs in the field. In the study, NCHRP350, which is the performance standard of expressway safety features of U.S. and materials related to the TMA standard in Europe have been reviewed to establish the Korean performance criteria. Based on the review, and incorporating existing Korean standard for crash cushions, domestic standard for TMA has been proposed and applied in developing Korean TMA and crash tested it to verify the performance. The original design developed was crash tested and modified. The newly proposed design was studied using impact simulation program several times. Modifications were made after each simulation and prototype was built and crash tested as per the newly established TMA performance criteria.

Some of the petroleum products contain benzene which is well known as a confirmed human carcinogen. For example, gasoline products contain benzene ranging up to several percents by weight. High exposures to the benzene and other organic solvents would be likely to occur during intermittent tasks and or processes rather than continuous jobs such as sampling, repair, inspection, and loading/unloading jobs. The work time for these jobs is various. However, most of work time is very short and the representative time interval is 15 minutes. Thus, it is preferable to do exposure assessment for 15 minute time weighted average which is known as a short time exposure level(STEL) by ACGIH rather than for 8-hours TWA. It is particularly significant to the exposure monitoring for benzene since it has been known that the exposure rate plays an important role to provoke the leukemia. Due to the large variations, a number of processes/tasks, the traditional sampling technique for organic solvents with the use of the charcoal and sampling pumps is not appropriate. Limited number of samples can be obtained due to the shortage of sampling pumps. Passive samplers can eliminate these limitations. However, low sampling rates resulted in collection of small amount of the target analysts in the passive samplers. This is originated the nature of passive samplers. Field applications were made with use of passive samplers to compare with the charcoal tube methods for 15 minutes. Gasoline loading processes to the tank lorry trucks at the loading stations in the petroleum products storage area. Good agreements between the results of passive samplers and those of the charcoal tubes were achieved. However, it was found that special cautions were necessary during the analysis at very low concentration levels.
