AMPA Regional ITS Architecture Update

Element Expanded Functional Requirements: Independent School District Buses

Functional Area: On-board Schedule Management
  1. The transit vehicle shall receive a vehicle assignment including transit route information, transit service instructions, traffic information, road conditions, and other information for the operator.
  2. The transit vehicle shall use the route information and its current location to determine the deviation from the predetermined schedule.
  3. The transit vehicle shall calculate the estimated times of arrival (ETA) at transit stops.
  4. The transit vehicle shall determine scenarios to correct the schedule deviation.
  5. The transit vehicle shall provide the schedule deviations and instructions for schedule corrections to the transit vehicle operator if the deviation is small, or the transit vehicle is operating in an urban area.
  6. The transit vehicle shall send the schedule deviation and estimated arrival time information to the center.
  7. The transit vehicle shall support the operations of a flexible route service. This may include requests for route deviations that would then lead to schedule corrective actions.
  8. The transit vehicle shall notify the transit center of vehicle location and operational status as the vehicle exits and returns to the transit facility to support future vehicle assignments.
Functional Area: On-board Maintenance
  1. The transit vehicle shall collect and process vehicle mileage data available to sensors on-board.
  2. The transit vehicle shall collect and process the transit vehicle's operating conditions such as engine temperature, oil pressure, brake wear, internal lighting, environmental controls, etc.
  3. The transit vehicle shall transmit vehicle maintenance data to the center to be used for scheduling future vehicle maintenance.
Functional Area: On-board Transit Security
  1. The transit vehicle shall perform video and audio surveillance inside of transit vehicles and output raw video or audio data for either local monitoring (for processing or direct output to the transit vehicle operator), remote monitoring or for local storage (e.g., in an event recorder).
  2. The transit vehicle shall perform local monitoring of video or audio surveillance data collected inside of transit vehicles, and identify potential incidents or threats based on received processing parameters.
  3. The transit vehicle shall output an indication of potential incidents or threats and the processed video or audio information to the center along with the vehicle’s current location.
  4. The transit vehicle shall detect potential threats via sensors for chemical agents, toxic industrial chemicals, biological agents, explosives, and radiation.
  5. The transit vehicle shall detect potential threats via object detection sensors (e.g. metal detectors).
  6. The transit vehicle shall output an indication of potential incidents or threats and the processed sensor information to the center along with the vehicle’s current location.
  7. The transit vehicle shall accept sensor control data to allow remote control of the sensors.
  8. The transit vehicle shall monitor and output surveillance and sensor equipment status and fault indications.
  9. The transit vehicle shall accept emergency inputs from either the transit vehicle operator or a traveler through such interfaces as panic buttons, silent or audible alarms, etc.
  10. The transit vehicle shall output reported emergencies to the center.
  11. The transit vehicle shall receive acknowledgments of the emergency request from the center and output this acknowledgment to the transit vehicle operator or to the travelers.
  12. The transit vehicle shall be capable of receiving an emergency message for broadcast to the travelers or to the transit vehicle operator.
  13. The transit vehicle shall be capable of disabling or enabling the transit vehicle based on commands from the center or authentic inputs from the transit vehicle operator.
  14. The transit vehicle shall perform authentication of the transit vehicle operator.
  15. The transit vehicle shall monitor and output surveillance equipment status and fault indications.
