On the basis of analyzing the control problems of single intersection, a kind of real-time method with PSO (Particle Swarm Optimization) solving signal timing for single intersection is put forward. On detecting the flow of current cycle and the cycle before, estimating the flow of next circle is proceeded through the linear pre-estimation method. Setting least delay as performance index, each phase time for the next cycle can be obained. A simulation experiment for the traffic model at a four-phase intersection is also demonstrated. The result shows that the method is efficient.
