Abstract

The road network investment that has been carried out continuously is one of the most important projects and is still needed. After the Great East Japan Earthquake, the road network evaluation methods independent from the probability of disaster occurrence is required. Based on these backgrounds, this research attempts to evaluate an impact of road investments in a long-term period by using the network topological method, that is independent of event occurrence probability and traffic demand. The road networks from 1985 to 2024 in Gifu Prefecture are evaluated by an eigenvector centrality analysis considering traffic capacity and link length as weights. The result verifies that the impact of road investments on the road supply performance can be identified by the proposed method.
