Abstract
Rural areas play important roles in national land planning. However, with rapid changes related to the ever-declining birthrate and graying of society as well as financial reforms due to financial constraints, "village collapse" has become increasingly obvious, and the survival of rural areas is now at risk. In light of this situation, journey-time reliability of road transportation could become an important key in supporting the sustainable development of production and living-related activities in rural, mature communities in the future. In this study, the importance of journey-time reliability of road transportation for the activities of rural residents is examined by referring to the concept of a time-space path and the population movement theory. In addition, the value of journey time reliability is quantified using the stated preference survey.
