Abstract: To address the di±culties for current parking systems, this paper presents a novel urban parallel parking system based on the ACP method. This system is consisted of three main steps: the construction of the artificial parking system, the computational experiments to provide a decision method for the management and control of the parallel parking system, and the parallel execution between the artificial parking system and the actual parking system to achieve the rolling optimization for the management and control of parking systems. The proposed parallel parking system can not only bring the more convenient parking process and the more effective parking resource allocation, but also provide the optimum implementation scheme for the parking lots. Finally the urban parking problem could be solved effectively for different parking needs.
