Since accidents of hazardous material transport vehicle on roadways cause severe damage in the form of disaster, foreign countries have long been engaged in systematic management and establishment of relevant laws and policies for the road safety. Recently, over 10-kilometer long tunnel, such as Inje-Yangyang Tunnel and Geumjeongsan Tunnel, has been opened on the expressway and the production of various hazardous materials is increasing with the development of chemical technology. However, road laws related to the safe operation of hazardous materials transport vehicles are still lacking, and policy measures for managing them have not been specified. It is an important task to recognize the risk of accidents of hazardous material transport vehicles and to secure road safety by establishing a management plan for road managers. Therefore, this study analyzed the feasibility of the traffic regulation of expressway tunnel in South Korea and suggested a direction for management. The results of this study can be utilized as the primary data for the revision of law related to hazardous materials transport vehicles on roadways and the derivation of optimal route of hazardous materials transport vehicles.

In order to reduce Green House Gas(GHG) reduction in the road freight sector and thus establish green logistics, running efficiency of goods vehicles is of paramount importance. Providing effective transportation infrastructure can contribute to achieve the green logistics by reducing empty running of heavy goods vehicles and van, increasing the average payload on the vehicle, and shifting the transportation mode. In order to reduce the environmental impact from the road freight sector, it is essential to quantify the amount of environmental loading from the sector. However, any systematic survey on the environmental loading from the logistics companies has not been carried out in Korea. In this study, the environmental index for the road freight sector is defined as the amount of $CO_2$ emission per ton km generated from goods vehicles. The computational analysis shows that the average $CO_2$ emission per ton km generated by the logistics companies in Korea is $363g-CO_2/ton{\cdot}km$. Compared to UK (=$130g-CO_2/ton{\cdot}km$) and France (=$97g-CO_2/ton{\cdot}km$), the efficiency of logistics in Korea is 2.8 and 3.7 times as low as in the advanced countries. It also indicates that the main reasons for the low efficiency are mainly due to the high rate of empty operation of goods vehicles and the low payload.

운송 서비스산업에 대한 지속적인 규제완화는 운송 기업의 진입 및 퇴출을 자유롭게 하였고, 외국 기업의 국내에서의 영업 활동이 가능하게 했을 뿐 아니라, 업종간 분류를 무의미하게 하여 운송기업은 전방위 경쟁을 피할 수 없게 되었다. 이러한 경쟁 환경하에서 운송 기업의 효율적인 운영은 국가 물류비 절감 측면에서, 그리고 해당 기업의 사활 측면에서 매우 중요한 의미를 갖는다. 소화물 일관 수송은 택배 또는 특송이라 불리우는 운송 서비스업의 일종으로, 화주 한명의 화물량이 차량 한 대 분량에 못 미치고, 고객이 원하는 출발지에서 목적지까지 운반해주는 특성을 가지고 있다. 소화물 일괄 수송은 지역을 순화하면서 화물을 접수하여 인근 터미널까지 운반하는 수집과정, 터미널과 터미널을 연결하는간선수송 과정, 터미널에서 최종 목적지까지 운반하는 배달과정을 거쳐 이루어진다. 본 연구를 통하여 터미널과 터미널을 연결하는 간선 수송과정에서 발생하는 비용을 줄이는 화물운송경로를 찾아주는 네트웍 최적화 모형이 개발되었으며, 이를 실제 업무에 적용하여 화물운송 경로를 조정함으로써 적재율 20%이상 개선, 운송비용 10%이상 절감이 가능함을 확인하였다.

The purpose of this study is to improvement strategies for transportation systems of container cargo in Busan port. Therefore, it was forecasted the future container cargo demand using logistic curve formula. In 2011, container cargo demand was forecasted 8.791 million TEU(T/S including 12.559 million TEU). In order to improvement transportation systems of container cargo, this study presented following; $\circled1$ port facilities expansion, $\circled2$ diversity of container transport modes. $\circled3$ make up ICD and exclusive container roads, $\circled4$ the second Seoul-Busan Expressway.

The purpose of this study is to improve the strategies for transportation systems of container cargoes in Busan port. Therefore, container cargoes forecasting is done through logistic methods based on past trends. In 2011, container cargoes demand was forecasted 8.791 million TEU(T/S including 12.559 million TEU). In order to improve transportation systems of container cargoes, the conclusions of this study can be summarized as follows ; \circled1 port facilities expansion, \circled2 diversity of container transport modes, \circled3 make up ICD and exclusive container roads, \circled4 the second Seoul-Busan Expressway.

국내 철도사업은 1899년 경인선이 개통된 이래 1970년대까지 지역 간 수송수단으로써 여객은 물론 산업물자 수송 등을 통해 국가 경제 발전의 초석이 되었으나, 1970년대 이후 고속도로의 투자와 함께 자동차 대중화 시대를 맞이하면서 철도는 도로교통에 지배적 위치를 내어 주게 되었으며 계속되는 투자부족과 수송시장의 변화에 대처하기 어려운 철도운영체계로 인해 서비스 수준 저하, 수요감소, 수입 감소로 이어지면서 경영적자를 야기하고, 이러한 재정적 어려움은 재투자를 어렵게 하는 등의 구조적 악순환이 반복되고 있다.(중략)
