Risk Analysis and Ranking Method for an Expressway Infrastructure Protection Plan

Abstract

Critical infrastructure has established the protection plan by designating nine areas such as transportation and energy. State infrastructure is normalized when it is organically moved by referring to the facilities that are of core importance to the country. There are railways, highways, air transportation, and others in the transportation sector. Korea Expressway Corporation is a disaster management authority responsible for highways nationwide. For the normal operation of critical infrastructure, it is necessary to conduct risk assessment of management facilities and establish protection plans. The government requires the selection of key risks through the assessment of relative risk by facility type and disaster type. According to the Guidelines for Establishing Critical Infrastructure Protection Plan, it is necessary to judge the probability of occurrence and the scale of damage (human, economic, and functional) in the risk analysis stage. In this study, we analyze disaster cases and determine the degree of likelihood and the consequences in order to assess the risks according to the characteristics of highways of critical infrastructure. Risk assessment was conducted through the creation of a reference table, and the result of relative risk for each disaster type was derived.

Risk Assessment in Practice: A Case Analysis of the Pohang Steel Mill in Korea

“…In addition, there are various risks arising from rapid social and environmental changes worldwide, such as active inter-industry exchanges and climate change. Therefore, as a national infrastructure and facility with the highest security level, a risk assessment of the Pohang Steel mill is essential [3]. The ultimate purpose of the risk assessment is to analyze and evaluate various risk factors and finally establish countermeasures for each risk factor [12].…”

“…The national infrastructure is closely related to the national economy and people's lives. National infrastructure must be protected from risk factors, such as management crises, accidents, and natural disasters [3]. For the continuous operation of the Pohang Steel mill, it is necessary to identify risks that hinder operations and weaken competitiveness, analyze and evaluate them, and prepare countermeasures accordingly.…”
