Hálózati-, idő- és költségtávolságok összehasonlítása a magyar vasúthálózaton

Absztrakt

The aim of this study is to discuss the differences between geographical, network, time and cost distances by the help of a small part of the Hungarian railway network. The source of data is the timetable of Hungarian Railway. In the first section the outline of the paper will be given. The second section deals with the validity of metrical axioms in time and cost space. Time and cost space are more complex than geographical space, because there is just one and only air kilometers and the kilometer distance between points of network can be determined more or less exactly. Time distances and cost distances fall into an interval and at best only about shortest or typical distances, shortest or typical lengths of time and least or typical costs can be spoken. The third and fourth sections compare the geographical space and the time and cost spaces, first by the help of detour indices and then with multidimensional scaling.
