교통사고는 인적피해, 물적피해, 사회적피해와 거시적으로는 심리적 피해까지 일으키며 많은 비용을 발생시킨다. 이처럼 교통사고로 인해 발생하는 다양한 피해요소를 비용으로 환산하여 추정하는 것은 교통안전사업의 절감편익을 산정하거나 기타 교통관련사업의 효과를 적용하기 위하여 활용할 수 있다. 하지만 현재까지 이루어진 사고비용 산출에 대한 연구론은 1당사자와 2당사자 구분없이 사고 전체를 아우르는 피해비용을 산출하는 방식의 접근 방법과, 사상자 1인 기준으로 발생되는 피해비용을 산출하는 방식의 접근 방법으로 나뉘며, 두 접근방법 모두 비용분석의 대상을 단일 객체로 간주하고 분석하는 한계를 지니고 있다. 이에 본 연구에서는 특정한 상호작용효과가 있을 것으로 예상되는 고연령 구간을 확인한 뒤 고연령 구간과 전체 연령 구간 사이에서 발생된 사고를 비교분석하여 1당사자와 2당사자가 모두 고연령 구간일 때 추가로 발생되는 사고비용을 산출 및 검정함으로서 고령자 사고감소효과 및 절감편익에 활용될 수 있는 상호작용 효과에 따른 추가 절감편익을 산출하였다.

Environmental Impact is getting more attention in many feasibility studies for railroad-related projects and research items. For sustainable growth and green transportation, the benefits typically used for feasibility studies in railway-related projects, are composed mostly of economic criterions which is not considering growing attention on changing paradigm. Based on the analysis of current methodologies, improvements in estimating environmental impact especially on noise and pollution are suggested.

수도권 광역상수도는 관로 매설 이후 30년 이상 경과하여 수도관로 사고 발생빈도가 증가하고 있다. 이에 노후관로를 갱생하여 사고예방과 용수공급 안정성 강화를 도모할 필요가 있으며, 이러한 사업의 수행 여부에 대한 판단을 위해서는 사업 시행으로 발생하는 경제적 편익에 대한 정량적 정보가 필요하다. 노후관로 갱생사업의 경제적 편익은 크게 관로사고 피해저감 편익과 복구비용 절감편익으로 구분되는데 후자는 공학적 접근을 통해 비교적 쉽게 평가할 수 있는 반면에, 전자는 평가가 어렵다. 이에 본 논문에서는 조건부 가치측정법이라는 경제학적 기법을 적용하여 관로사고 피해저감 편익을 추정하고자 한다. 수도권 광역상수도 갱생사업의 수혜지역 주민 600 가구를 무작위로 추출하여 수도권 광역상수도 갱생사업이 시행되지 않을 경우 관로사고가 발생할 수 있음을 설명한 후, 관로사고를 막기 위한 지불의사액을 조사하였다. 분석결과 관로사고 피해 회피를 위한 가구평균 지불의사액은 톤당 약 41.7원이었다. 이 정보는 노후관로 갱생사업에 대한 의사 결정시 활용할 수 있다.

The accident rate in South Korea is simply classified according to the road type and the number of lanes, but other countries apply various factors affect accidents. In this study, national highways where accidents occurred were divided into urban, rural, older, and modern roads using TAAS(Traffic Accident Analysis System) data, and a model of accident costs savings is suggested. As a result of analyzing 1,416.2 km, the fatality rate(person/100mil-vehicle·km) was 4.21 for urban-older, 1.37 for urban-modern, 2.18 for rural-older, and 0.99 for rural-modern roads. The rates of urban roads had a higher result than rural. The injury rate(person/100mil-vehicle·km) for urban-older was 182.63, that for urban-modern was 103.42, that for rural-older was 67.44, and that for rural-modern road was 42.96, which showed a similar pattern to fatality rates. Accident rates of a modern road were much lower than the KDI Guideline. The benefit of applying the result of this study was calculated and the valuation of accident costs savings is increased from 0.6% to 14.1%, while B/C is improved from 0.626 to 0.724.

This study aims to analyze the freight transport demand and benefit for the introduction of an automated freight transport system focusing on the Global Industry and Logistics City (GILC) in Busan. In pursuit of this aim, four alternatives were calculated - using the freight volume estimating methods and included, the number of businesses, the number of employees set up, future estimated cargo volume, and switched volume from other transport modes into the GILC. Economic benefits were analyzed against social benefits and costs accordingly. The result of the freight transport demand forecast found, the cargo volume of "Alternative 2-1" to be the most advantageous, applying the number of employee unit method and proportion of employees in Gangseo-gu, Busan. In addition to the conventional analysis of direct benefit items (reduction of transport time, traffic accidents and environmental costs), this study also considered additional benefit items (congestion costs savings, and road maintenance costs in terms of opportunity cost). It also considered advanced value for money research in guidance on rail appraisal of U.K, Federal Transport Infrastructure Plan 2003 of Germany, and RailDec of the United States. The study aims to further contribute to estimating minimum cargo transport demands and assess the economic feasibility of the introduction of new intermodal automated freight transport systems in the future.

The relationship between climate changes and transportation could be separated by two approaches. One of methods was to find how climate changes affected transportation, and the other way was how transportation affected climate changes. In this study, we reported from the former standpoint, how climate changes affected transportation fields. When there is a lot of snowfall in Seoul, it starts ripple effect through the travel patterns. They can be explained by travel time and operating cost. The travel costs were calculated in this paper for analysing the effect of disbenefit by climate changes. Snow Melting System was also studied for relieving negative influences under the unpredictable weather condition. As a result, the system was effective for minimizing disbenefit by climate changes.

Visibility of lane marking is impaired at night, or in case of rain, and thereby threatens traffic safety. Recently, various studies and technology have been developed to improve lane marking visibility, such as the extension of lane marking life expectancy (up to 1.5 times), improvement of lane marking equipment, improvement of lane marking visibility (32.7%) by applying phosphorescent material mixed paint, and expressway lane design standards alternative (length 6m, gap 12m, width 13cm: 27.8% of painted surface are reduced) adoption with ergonomic analysis. In this study, a set of cost-benefit analyses was performed for the cases where such techniques were applied. Based on the literature review, 26.9% of traffic accidents would be prevented by improving lane marking visibility by 32.7%; accident reduction benefit was calculated as much as 12.5 billion KRW. Meanwhile, total increased cost when introducing phosphorescent material mixed paint and lane design standards alternative is calculated as 30.6 billion KRW. However, economic feasibility could not be secured with 0.41 of cost-benefit ratio when applied to the expressway network as a whole. Additionally, cost-benefit (B/C) analysis was applied to each of the top 20 night accident hot spots and the results of B/C ratios were between 0.67 and 4.20, showing that 11 out of 20 spot sections of expressway can have economic feasibility. This results indicate, with this kind of pavement marking applied to accident hot spots in rural expressway, better visibility and economic feasibility can be guaranteed through traffic accident reduction. Some limitations and future research agenda have also been discussed.

Visibility of lane marking is impaired at night or in the rain, which thereby threatens traffic safety. Recently, various studies and technologies have been developed to improve lane marking visibility, such as the extension of lane marking life expectancy (up to 1.5 times), improvement of lane marking equipment productivity, improvement of lane marking visibility by applying phosphorescent material mixed paint. Cost-benefit analysis was performed with considering various benefit items that can be expected. About 45% of traffic accidents would be prevented by improving lane marking visibility. Additionally, accident reduction benefit and traffic congestion reduction benefit were calculated as much as 246 billion KRW per year and 12 billion KRW per year, respectively, by reducing repaint cycle due to enhanced durability. 45 billion KRW per year is expected to reduced with improved lane detection performance of autonomous vehicle. Meanwhile, total increased cost when introducing phosphorescent material mixed paint to 91,195km of nationwide road is identified as 1922 billion KRW per year. However, economic feasibility could not be secured with 0.16 of cost-benefit ratio when applied to the road network as a whole. In case of "Accident Hot Spot" analyzing section window (400m), one or more fatality or two or more injured (one or more injured in case of less than 2 lanes per direction) per year were caused by pavement marking related accident, economic feasibility was secured. In detail, 3.91 of cost-benefit ratio is estimated with comparison of the installation cost for 5,697 of accident hot spot and accident reduction benefit. Some limitations and future research agenda have also been discussed.
