Anomalous phenomena detector
View Patent ↗Techniques are disclosed that utilize various devices, sensors, and/or systems as data points in a transportation system to establish normal operation of the transportation system and determine when one or more of the devices, sensors, and/or systems provides anomalous data indicative of a problem in the transportation system.
