| Outline of Final Research Achievements |
Since natural disasters often occur, constructing a highly reliable highway network for national resilience is an urgent necessity. However, it is difficult to improve all the links due to budget constraints. Therefore, it is important to select a quantitative index for importance analysis; identifying key links to improve network reliability. Then, network reliability is efficiently improved and maintained. Reliability analysis and importance analysis methods are developed by authors. However, there are some subjects in applying these analyses to a large size highway network. Thus, this research discusses these problems.Importance analysis has two major areas of concern; developments of a new index and reduction of calculation work and memory size. Thus, the research aims to develop the relevance of an index proposed by the authors and develop an efficient method for approximate calculations. This paper focuses on the approximate calculation method for a large size highway network.
