Local Control of Traffic Flows in Networks: Self-Organisation of Phase Synchronised Dynamics — Stefan Lämmer¹, •Reik Donner¹, and Dirk Helbing² — ¹TU Dresden, Andreas-Schubert-Str. 23, 01062 Dresden, Germany — ²ETH Zürich, Universitätstr. 41, 8092 Zürich, Switzerland

The effective control of flows in urban traffic networks is a subject of broad economic interest. During the last years, efforts have been made to develop decentralised control strategies that take only the actual state of present traffic conditions into account. In this contribution, we introduce a permeability model for the local control of conflicting material flows on networks, which incorporates a self-organisation of the flows. The dynamics of our model is studied under different situations, with a special emphasis on the development of a phase synchronised switching behaviour at the nodes of the traffic network. In order to improve the potential applicability of our concept, we discuss how a proper demand anticipation and the definition of a priority function can be used to further optimise the performance of the presented strategy.
