| Functional Object | Description | User Defined |
|---|
| 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, manages allow/block lists and performs token validation. Collected fare data are made available to the center. | False |
|---|
| Transit Vehicle On–Board Information Services | 'Transit Vehicle On–board Information Services' furnishes en route transit users with real–time travel–related information on–board a transit vehicle. Current information that can be provided to transit users includes transit routes, schedules, transfer options, fares, real–time schedule adherence, current incidents, weather conditions, non–motorized transportation services, and special events are provided. In addition to tailored information for individual transit users, it also supports general annunciation and/or display of general schedule information, imminent arrival information, and other information of general interest to transit users. | 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 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 |
|---|
| Vehicle Basic Safety Communication | 'Vehicle Basic Safety Communication' exchanges current vehicle characteristics, location, and motion (including past and intended maneuver) information with other vehicles in the vicinity, uses that information to calculate vehicle paths, and warns the driver when the potential for an impending collision is detected. If available, map data is used to filter and interpret the relative location and motion of vehicles in the vicinity. Information from on–board sensors (e.g., radars and image processing) are also used, if available, in combination with the V2V communications to detect non–equipped vehicles and corroborate connected vehicle data. This object represents a broad range of implementations ranging from basic Vehicle Awareness Devices that only broadcast vehicle location and motion and provide no driver warnings to advanced integrated safety systems that coordinate maneuvers and may, in addition to warning the driver, provide collision warning information to support automated control functions that can support control intervention. | False |
|---|
| Vehicle Intersection Warning | 'Vehicle Intersection Warning' uses V2V and V2I communications to monitor other connected vehicles at intersections and support the safe movement of the vehicle through the intersection. Driver warnings are provided and the application may also optionally take control of the vehicle to avoid collisions. The application will also notify the infrastructure and other vehicles if it detects an unsafe infringement on the intersection. | False |
