Series A - General Colloquium:

The intention is to present general information not only to experts, but also to students and guests from outside the mathematical institutes.

A Paradoxon in Traffic Flow

The travelling time of a vehicle in a road network depends on the flows on the links. Therefore the traffic for each origin/destination pair is often distributed on several routes. It is a difference whether a system optimizer assign a route to every vehicle or each user tries to find the best route for himself. Therefore, in some situations it can happen that an addition of a new road to the network induces an increase of the travelling time for all drivers. The same effect can occur on the internet, but there the deterioration is bounded by 33 %.
