Functional Objects
| Functional Object | Description | User Defined |
|---|
| Transit Vehicle On–Board Connection Protection | 'Transit Vehicle On–Board Connection Protection' monitors vehicle schedule performance and provides it to the transit center for connection protection processing. It receives operator instructions relating to managing connection protection and recognizes individual travelers who have arranged for connection protection and provides connection protection information to the transit center. | False |
|---|
| Transit Vehicle On–Board Fare Management | 'Transit Vehicle On–board Fare Management' supports fare collection using a standard fare card or other non–monetary fare medium and detects payment violations. Collected fare data are made available to the center. | False |
|---|
| Transit Vehicle On–Board Maintenance | 'Transit Vehicle On–Board Maintenance' collects and processes transit vehicle maintenance data on–board the vehicle, including mileage and vehicle operating conditions. This maintenance information is provided to the management center and used to schedule future vehicle maintenance and repair. | False |
|---|
| Transit Vehicle On–Board Trip Monitoring | 'Transit Vehicle On–Board Trip Monitoring' tracks vehicle location, monitors fuel usage, collects operational status (doors opened/closed, running times, etc.) and sends the collected, time stamped data to the Transit Management Center. | False |
|---|
| Transit Vehicle Passenger Counting | 'Transit Vehicle Passenger Counting' collects transit vehicle loading data and makes it available to the center. | False |
|---|
| Transit Vehicle Schedule Management | 'Transit Vehicle Schedule Management' monitors schedule performance and identifies corrective actions when a deviation is detected. It provides two–way communication between the transit vehicle and center, enabling the center to communicate with the vehicle operator and monitor on–board systems. | False |
|---|
| Transit Vehicle Security | 'Transit Vehicle Security' provides security and safety functions on–board the transit vehicle. It includes surveillance and sensor systems that monitor the on–board environment, silent alarms that can be activated by transit user or vehicle operator, operator authentication, and a remote vehicle disable function. The surveillance equipment includes video (e.g. CCTV cameras), audio systems and/or event recorder systems. The sensor equipment includes threat sensors (e.g. chemical agent, toxic industrial chemical, biological, explosives, and radiological sensors) and object detection sensors (e.g. metal detectors). | False |
|---|
| Transit Vehicle Signal Priority | 'Transit Vehicle Signal Priority' provides the capability for transit vehicles to determine eligibility for priority and request signal priority at signalized intersections, ramps, and interchanges through short range communication with traffic control equipment at the roadside. | False |
