A freeway with vehicles transmitting traffic-related messages via short-range radio is a technological representation for a complex network: A dynamical process runs on a network with dynamical topology. Here the network dynamics can strongly influence the message propagation because it is of the same timescale. In addition, if the cars generate the messages concerning irregularities in the traffic flow and also react to such information generated by other cars, the system has a feedback loop from the network topology to the generation of messages and from the message propagation to the network topology. The complexity of this system is restricted by its one dimensionality, i.e., the network nodes are distributed in one dimension, but moving in different directions. By microscopic simulation of congested freeway traffic, where a certain fraction of cars are equipped with inter-vehicle-communication facilities, we investigate how the equipment level influences the efficiency of transmitting traffic related information such as the position of jam fronts.
