Abstract: In order to realize the cooperative control for two adjacent intersections,the signal control for two intersections is put forward based on the method,which the traffic signal control for an isolated intersection has been resolved by Q-Learning.According to the switching-model for two intersections,the combination phase of two intersections is advanced in order to transform two intersections to a single one.So the coopera- tion control for two intersections can be resolved by general Q-Learning.It is illustrated by Paramics simula- tion software that the method is effective and feasible.
