Cools, S.B., C. Gershenson, and B. D'Hooghe (2006). Self-organizing traffic lights: A realistic simulation. Submitted.

Abstract:We have previously shown in an abstract simulation (Gershenson, 2005) that self-organizing traffic lights can improve greatly traffic flow for any density. In this paper, we extend these results to a realistic setting, implementing self-organizing traffic lights in an advanced traffic simulator using real data from a Brussels avenue. On average, for different traffic densities, travel waiting times are reduced by 50% compared to the current green wave method.
