  • This study aims to provide a methodological framework to estimate the travel demand of hazardous materials transporting vehicles by link and analyze daily traffic patterns on an expressway to develop safety roadway management strategies. Traffic volume of hazardous material vehicles is counted through the on-site investigation at twenty-five tollgates on the expressway, and their demands by a link are predicted through origin-destination flows estimation. The result shows that the number of the domestic hazardous materials vehicles is approximately 51,207 vehicles per day and it indicates that hazardous materials transport vehicles account for 1.5% of total daily traffic on the internal expressway and 6.2% of total cargo traffic volumes. This study roughly estimated how many hazardous materials vehicles pass through the expressway segment. Thus it is expected to be utilized for establishing a systematic highway management strategy in the future by calculating the traffic volume of the hazardous material vehicles traveling on the interstate expressway.

  • Many countries are managing the transportation of hazardous materials under the specific provisions especially, as well as use, storage and management, because of their high risks. For the purpose of the revision of rail safety law for the safe transportation of hazardous materials, amount and kind of hazardous materials transported by rail in Korea are analysed and the standards of classification of hazardous materials are compared in domestic and abroad. There are lots of benefits for national rail safety law to implement an international law because our country's geographic location is convenient to connect the continent and to across the border. It is suggested that implementing a classification and test methods of hazardous materials enable to use internationally for the preparation of rail transportation to be increased.

  • Vehicles transporting hazardous materials can make huge damage to people, properties and environment by traffic accidents. Therefore, transporting hazardous materials is a big issue with the cutting edge technology of communications in these days. However, despite this situation, Korean government gives limited efforts for systematic management, research and investment about hazardous materials. Accordingly, this research suggests the key path finding algorithm about management of real-time schedule and routes for vehicles transporting hazardous materials. Besides, the case study is progressed in transportation networks of Seoul in order to evaluate the reality of algorithm. Specifically, time-space network transformation is performed for time window attributes. In addition, this study proposes the techniques searching for non-dominated paths considering schedule by the multiobjective shortest path algorithm based on dynamic programming in dynamic transportation networks including multiobjective attributes.

  • Ministry of Environment developed ‘Emergency Response Information System (ERIS)’ in 2001, which is in operation. As a next step, currently National Emergency Response Information System (NERIS) is being developed. The main difference among ERIS and NERIS is to enhance the system in the national level, including transportation of hazardous materials. This paper introduces concepts and methods applied to NERIS, especially HAZMAT, and the information system, operating strategies. Based on GIS and transportation-network data, the best route can be offered using Risk Analysis. Strategies for reporting and first-response information systems are also designed for emergencies in the paper.

  • 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.

  • 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.

  • This study evaluated a preventive information communication system for the storage, handing, and transportation of hazardous materials according to the hazardous materials safety management law of Korea. At present, the chemical management system has very little information on accident responses due to a problem in the initial response. Therefore, this study was designed to improve the hazardous materials safety management law as an advanced method for simultaneous accident prevention and response, such as GHS system. This can also cause confusion in industry, such as manufacturing and import-export companies, because safety management laws and the GHS system are very different from the hazard classification systems. This study suggests a harmonization plan between the hazardous materials safety management law and the GHS classification system through an analysis of the hazardous materials classification system of major advanced countries.

  • Controlling the quality of indoor air is important in order to maintain a healthy life. In this study, we investigated the correlation between the hazardous substance concentration of indoor air and circulation based on different ventilation methods in the apartment, which is one of the representative housing types in Korea. As target substances, we considered the hazardous substances which are generated during the cooking process and radon gas which is originated from building materials. We measured the concentrations of carbon dioxide and fine particles in relation to type of food and ventilation methods in order to determine the change in the concentration levels of hazardous substances which are generated during the cooking process. On the other hand, we measured the concentration of radon gas before and after letting fresh air into a room through windows in order to determine the change in the concentration level of radon gas which is originated from building materials. The results show that turning on the ventilation fan plays a major role in reducing the concentration levels of hazardous substances in the kitchen, and that it is more effective to turn on the ventilation fan during cooking than after cooking to prevent the diffusion of hazardous materials produced by cooking through the indoor air. Also, the results indicate that letting fresh air into a room through windows more than one time a day is necessary to reduce the concentration level of radon gas in the room to safe concentration range.
