Abstract: To solve the traffic control problem on oversaturated linear network，the total delay is divided into two parts：the feeding delay and the non-feeding delay，and the control problem is formulated as a conflicted multi-objective control problem.According to the character that the optimal point is not single in the conflict multi-objective control problem and optimal solutions cannot be simultaneously obtained by traditional optimization methods in a single run，a new compatible control algorithm based on preference is proposed，which incorporates user’s preference information into optimization process for obtaining dense Pareto solutions in preference region，and a new selection function is defined to make control objectives stabilized in this region.The proposed compatible optimization control algorithm is used to solve the oversaturated traffic linear network control problem in a core area of seven junctions under the simulation environment.It is proved that the proposed algorithm can handle the oversaturated linear network control problem effectively than the fixed-time control method.
