Functional Areas

Advanced Rail Crossing

• The field element shall close the highway-rail intersection (HRI) when a train is approaching with enough time for traffic to safely clear the crossing using gates, lights/signs, barriers, and traffic control signals.
• The field element shall collect and process, traffic sensor data in the vicinity of a highway-rail intersection (HRI).
• The field element shall collect pedestrian images and pedestrian sensor data, and respond to pedestrian crossing requests via display, audio signal, or other manner.
• The field element shall determine whether the highway-rail intersection (HRI) is blocked by traffic in the roadway or some other obstruction.
• The field element shall forward rail traffic advisories received from the Wayside Equipment to the traffic management center.
• The field element shall monitor the status of the highway-rail intersection (HRI) equipment, including both the current state and mode of operation and the current equipment condition, to be forwarded on to the rail wayside equipment.
• The field element shall monitor the status of the highway-rail intersection (HRI) equipment, including both the current state and mode of operation and the current equipment condition, to be forwarded on to the traffic management center.
• The field element shall notify the traffic management center and the rail wayside equipment of any intersection blockages, including trapped vehicles or other obstructions.
• The field element shall provide approaching train advisories using field-vehicle communications to vehicles approaching the grade crossing.
• The field element shall receive track status and arriving train information from the rail wayside equipment that can be passed on to the traffic management center. This may include the current status of the tracks and when a train is expected and/or how
• The field element shall support the integrated control of adjacent traffic signals to clear an area in advance of an approaching train and to manage traffic around the intersection.

HRI Traffic Management

• The center shall accept collect highway-rail intersection (HRI) advisory or alert data from rail operations centers.
• The center shall collect highway-rail intersection (HRI) equipment operational status and compare against the control information sent by the center.
• The center shall collect incident information related to a highway-rail intersection (HRI), such as intersection blockages or crashes or equipment malfunctions.
• The center shall implement control plans to coordinate signalized intersections around highway-rail intersections (HRI), under control of center personnel, based on data from sensors and surveillance monitoring traffic conditions, incidents, equipment fau
• The center shall provide the highway-rail intersection (HRI) equipment operational status to rail operations centers.
• The center shall remotely control highway-rail intersection (HRI) equipment located in the field.
