1. A method of detecting anomalous phenomena in a transit system implemented by an anomaly detector, the method comprising:
- obtaining, over a period of time by the anomaly detector, data from a plurality of data sources of the transit system, the data sources including journey planners, traffic system(s), access control points, transit ticket vending machines, ticket booth computers, emergency sensor(s), user input interface console, and location system(s), all of the transit system;
for each data source of the plurality of data sources, defining, by a data monitoring module of the anomaly detector, a range of data values indicative of normal operation of the transit system, based on data values obtained for the data source over the period of time;
subsequent to defining the range of data values for each data source of the plurality of data sources, obtaining, by the anomaly detector, additional data from a particular data source of the plurality of data sources;
comparing, by the anomaly detector, using a processing unit, a value of the additional data from the particular data source to the corresponding defined range of data values for the particular data source;
determining, by the anomaly detector, based on the comparison, that an anomalous event has occurred in the transit system including a particular one or more transit system station or stop affected by the anomalous event;
in response to determining the occurrence of the anomalous event in the transit system, determining, by the anomaly detector, from a plurality of predetermined response plans, a response plan to implement;
sending by the anomaly detector, at least one message to system devices, personnel and passengers, of the transit system in accordance with the determined response plan to implement; and
implementing the response plan by including automatically aliasing passenger tickets to permit the passenger tickets to work if the passengers exit or enter a transit system station or stop that is before or after a determined affected transit system station or stop.

Abstract
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. Identifying a problem and/or implementing a solution can then be partially or fully automated, to help ensure a quick response and minimal disruption in service.
