Abstract

Hazardous materials (HazMats) are substances that are flammable, explosive, toxic, or harmful, if released into the environment. Since the transportation of HazMats increases in many developed countries, HazMat transportation has the key function in the process of HazMat usage to trace information of production, storage, shipment, usage, and waste disposal. The Korean Ministry of Environment (KMOE) and the National Emergency Management Agency (NEMA) have developed many laws, regulations, and standards for hazardous materials. However, the Korean HazMat laws, regulations, and standards do not guarantee accurate information of HazMat origin-destination (O-D) shipments, though the HazMat O-D movement is the critical information in safety and security of HazMat transportation. The objectives of this research are: (1) to investigate emerging and recurrent issues in Korean HazMat transportation, and (2) to develop the estimation method of O-D matrices for hazardous materials under limited data sets. The sodium hydroxide waste shipment among forty candidate HazMats is selected as the sample research case. The growth-factor method is applied to estimate the 2005 O-D matrix of sodium-hydroxide waste shipment. The column-and-row factoring process is used to calibrate the estimated sodium-hydroxide O-D matrix. The result shows the applicability of the O-D estimation process for hazardous materials. The Sodium Hydroxide Waste Origin-Destination Matrix is obtained to trace routes and paths of the Sodium Hydroxide transportation.

유해물질은 만일 누출된다면 화재 폭발 독성 및 위해성이 있는 물질을 말한다. 많은 선진국에서 유해물질의 수송이 증가하고 있기 때문에 유해물질의 생산 저장 수송 사용 및 폐기에 대한 정확한 정보는 매우 중요하다. 유해물질의 수송은 유해물질의 사용과정에서 핵심적인 기능이라고 말할 수 있다. 정부는 유해물질에 대해 많은 법령과 규제, 기준들을 개발해 왔다. 그러나 한국의 법령, 규제, 기준들은 비록 유해물질의 이동이 유해물질 수송에 대한 안전과 방재차원에서 중요한 정보임에도 불구하고, 유해물질의 O-D수송에 대한 정확한 정보를 보장하고 있지 못한 실정이다. 본 연구의 목적은 한국의 유해물질 수송에 대해 새롭게 대두되거나 기존에 제기된 이슈들을 조사하고, 제한된 자료를 가진 상황에서 유해물질에 대한 O-D매트릭스를 예측하는 기법을 개발하는 것이다. 본 연구는 유해물질 수송사례에 대한 40개의 후보군 중에서 수산화나트륨 폐기물에 대한 수송이 사례 연구로 선정하였다. 성장률법이 수산화나트륨 폐기물 수송의 2005년 O-D매트릭스를 추정하는데 적용되었다. 행렬보정기법이 추정된 수산화나트륨 O-D매트릭스를 보정하는데 사용되었다. 본 연구는 유해물질에 대한 O-D추정기법의 적용가능성을 제시하였다. 본 연구를 통해 도출된 수산화나트륨 폐기물 O-D 매트릭스는 수산화나트륨 수송의 수송로와 수송구간을 추적하는데 사용되어 진다.
