Flows of cars and neural spikes enhanced by colored noise Academic Article uri icon

abstract

  • The problem of interaction between cars at road junctions has been studied for a long time. It is well-known that the interaction generally decreases the traffic efficiency and that randomness in the car flow can help cross-junction traffic efficiency. We show that proper long-range correlations in the flow noise, related to 1/f-like noises, provide superior traffic properties as compared to Poissonian or periodic car traffic. Moreover, a stochastic resonance phenomenon sensitive to the shape of the spectrum occurs. By a small modification, the model can be made relevant for neuronal spike traffic. Spike trains generated by Gaussian 1/f noise show superior spike traffic properties and efficiency of information transfer. (C) 2000 Published by Elsevier Science B.V.
