物联网环境下城市交通区域联动的云控制策略

针对城市道路交通中的区域联动控制问题, 利用交通物联网所提供的实时交通信息以及不同交通控制节点之间的关联关系, 构建符合区域协调控制要求的交通云计算平台, 使得道路交通各交叉口之间的控制策略由云计算平台统一支配, 同时强化交通物联网技术在交通信息获取时的相互协同性, 结合各节点控制任务抵达云计算平台的突变随机性, 并考虑道路交通中控制节点执行状态的动态变化特征, 从而建立城市道路交通区域联动控制的云策略模型, 从执行性能和计算功率两方面对云计算平台在多节点联动控制时的运行情况进行分析。实验结果表明, 提出的区域交通联动控制云策略在大幅度降低云计算平台运行能耗的前提下, 保证了道路的通行效率。

Cloud computing strategy of coordinated control inurban region traffic things networking

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 contol 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.
