    摘要： A method for predicting failure of a crossing warning system is disclosed. The method includes monitoring an electrical characteristic of a first route when an electric current is injected into the first route. The first route has a crossing intersection with a second route and a crossing signal at the crossing intersection. The electrical characteristic is monitored to detect when a vehicle is approaching the crossing intersection on the first route and to determine when to activate the crossing signal at the crossing intersection. The method also includes identifying one or more changes in the electrical characteristic of the first route, and, based on the one or more changes that are identified, predicting a failure mode of the first route that interferes with detection of the vehicle approaching the crossing intersection.

    摘要： A vibration monitoring system includes an acoustic device that outputs an analog signal to a fiber cable for calibration and location verification. The acoustic device utilizes GPS or communication from wayside bungalow equipment to verify GPS location or real-time clock information. The wayside bungalow contains communication equipment that interfaces with the acoustic device and relays health information to a sensing processor. The sensing processor is configured to detect the acoustic signal output by the acoustic device at a known location and verifies that the cable and device have not moved location by comparing the signal level received against a threshold stored in memory. When the threshold is exceeded, the sensing processor sends an alert that the fiber optic cable or acoustic device at the location have changed.

    摘要： A system includes a detection module, a control module, an input module, and a determination module. The detection module is configured to obtain information from one or more detectors corresponding to a condition of a transportation network. The control module is configured to issue control messages using the information obtained. The input module is configured to receive a request for the control module to enter a test mode corresponding to an alteration of at least one of an input or an output of the control module from an operational mode. The determination module is configured to determine if an authorization condition corresponding to a physical state of one or more functional activity module of the transportation network is satisfied. The control module is transferred to the test mode if the authorization condition is satisfied and maintained in the operational mode if the authorization condition is not satisfied.
