Based on the traffic interrupted flow characteristics of a urban road network, this paper introduced the microscopic method of signal intersection delay calculation into the macroscopic theory for equilibrium network signal setting problem, establishing a medium bi-level programming model to optimizing the urban road network intersection signal, devising an optimization algorithm based on the genetic operation. One road network was set to test the model and its algorithm, and the superiority of the model was proved by comparing with the two signal setting methods, which was in microscopic and macroscopic view, respectively.
