However, in practice, there are many factors that influence cost of edges such as weather, time of day, and vehicle type. Then, the costs of edges in graphs always change over time. Therefore, finding shortest path needs to be considered not only distance but also factors affecting road speed. In this paper, we addressed the problem of computing fastest paths underlying future transportation with traffic speed patterns to non-stop intersections. A system model is proposed to show how a finding path processing is performed in future transportation. By defining the path cost, we propose an efficient finding path algorithm to compute a costoptimal path.
