According to the coordinated control problem of urban region transportation, this paper presented a traffic cloud computing platform, in which considered the relationship between different control nodes, to allocate control strategy for getting more reasonable the signal timing for different intersections in urban transportation, the growing Internet of things provided reference recommendations on the development strategy for transportation managements based on the characteristics of dynamic change of execution status among different control nodes and the random mutations in running of cloud computing platform. The experimental result shows that the proposed coorderate control cloud strategy is not only increase the traffic efficiency, but also reduce significantly the running energy consumption of cloud computing platform.
