QHM: The quantitative hierarchical model for network-level traffic management

The QHM framework offers a scalable approach to network-level traffic management, in short: Network Management (NM), which is the coherent management of traffic in large road networks. The framework consists of a recursive decomposition of large networks and a recursive control strategy. The framework distributes the complexity of NM among different levels and, per level, among a number of subnetworks, such that each management instance has only a limited amount of complexity to cope with. In this way, NM becomes feasible and scalable, such that it can be applied to heterogeneous networks of arbitrary size.
