Increasing mobility and the resulting rising traffic demands cause serious problems in urban regions world-wide. Approaches to alleviate the negative effects of traffic include an improved control of traffic lights and the introduction of dynamic route guidance (DRG) systems that take current conditions into account. Based on the self-organising Organic Traffic Control system, we introduce a novel DRG concept for urban road networks. It is inspired by the well-known Distance Vector Routing protocol from the Internet domain and increases the network's robustness with respect to congested or blocked roads. We demonstrate the efficiency of the developed approach in a simulation-based evaluation.
