Hierarchical routing in traffic networks

In this paper the design of a dynamic Routing system, called Hierar-
chical routing system, has been developed. It splits traffic networks into
several smaller and less complex networks by introducing a hierarchy. The
Hierarchical routing system therefore consists of several distributed Routing
systems where each of it is responsible for one network of the hierarchical
network. The route optimization is done with an adapted version of the
AntNet-algorithm, a decentralized routing algorithm, which uses intelligent
agents that explore the network and find the shortest routes in time. This
algorithm was derived from the behaviour of ants in nature.
