| Tiivistelmä: | This paper presents a modelling of natural obstacles in a road network for improving the commonly applied lower bound on the distance between two points: the Euclidean distance. Then, two applications of this new lower bound are proposed: the estimation of distances and an improvement of the Dijkstra algorithm. In both cases, the numerical experiments performed using the Swiss road network lead to obtaining very good results. |
