The extreme event of natural disaster has had a serious significant impact on transportation infrastructure in recent years. The management financial resources are to have some criteria to show the current condition of infrastructure based on the results from inspection databases. Highway systems are very important to transportation infrastructure, and the highway system in Taiwan is vulnerable to earthquake and typhoon. Vulnerability of a transportation infrastructure system is the susceptibility to incidents that can result in a considerable reduction in transportation network serviceability. Because the major rainfall of Typhoon MORAKOT was focused in mountainous area, most of highway system destroyed was in this mountainous area as well. For example, more than 600 kilometers of highway length and 196 bridges failed or were closed as a result of Typhoon MORAKOT. In addition, the main causes of infrastructure damage were heavy and long periods of precipitation, floods, and upstream watershed debris-flow. In this paper, according to the Typhoon MORAKOT experience learning, we described the impact and assessment of its region of influence in terms of their susceptibility to and the consequences of typhoon occurrences. In addition, a lesson is learned from this study regarding the key issues arising after Typhoon MORAKOT.
