The development of high-speed rail (HSR) is expected to significantly change the long- distance travel structure and transportation patterns. The changes are expected to be not only the increase in the number of tourists who use HSR service (direct effect), but also the change in the regional travel structures by encouraging the growth of several zones as network hubs (indirect effect). In this paper, a methodology to understand the change in the residential - travel destination zone matrix derived from mobile phone location data is proposed. The developed methodology is applied to determine the effect of the Hokuriku HSR on the nationwide long- distance travel patterns. The proposed methodology decomposed the matrix into two meaningful matrices, which can be understood as the direct and indirect effects of HSR. The decomposed results indicate the following three features of the HSR effects: First, the changes before and after the development of the Hokuriku HSR on the residential - travel destination zone matrix are mostly explained by two patterns of change by direct and indirect effect. Second, the direct numerical effects are less significant than the indirect effects. Third, the changes are asymmetric in direction in several zone pairs, because of the indirect effects.
