| Abstract: | Considered the limitation that ARC/INFO Pathfinding function only works on ArcNode Data Model, the paper discusses the case of public transportation network (PTN) and presents the tracing algorithm of two-way comparison. And the pathfinding function is extended to the Dynamic Segmentation Data Model. Therefore, a solution to the problem of the minimum cost path on PTN is provided. |
