As a result, anomaly detectors tested against simulated data and found effective may prove ineffective when deployed in real networks monitoring real traffic, he says.
DeVale说，因此，根据模拟数据测试并且发现有效的异常探测器在部署到真实网络中去监视真实流量的时候也许是没有效的。
The controller got flows and queues from its detectors to estimate traffic intensity, which was then used to determine whether the current signal phase should be extended or terminated.
控制器通过检测器获得的各车道交通流量和排队长度来判断各个相位的交通强度，进而决定是否延长或终止当前的信号相位。
