Abstract: When studying multiclass-user transportation networks Dafermos made a strong assumption on symmetry in order to prove existence of a user-optimizing flow pattern. In this paper existence is proved without the symmetry-hypothesis and it is shown that the methods of convex programming are not applicable.
