Functional Objects

Functional ObjectDescriptionUser Defined
Transit Vehicle Emissions Monitoring'Transit Vehicle Emissions Monitoring' directly measures or estimates vehicle emissions and provides current and average emissions measures to the Transit Management Center.False
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, 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 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 On–Board Vehicle Signing Communications'Transit Vehicle On–Board Vehicle Signing Communications' provides the capability for the transit vehicle to distribute information to vehicles in the vicinity for in–vehicle display. The information provided supplements external signs and signals on the transit vehicle and may include notification that the vehicle (e.g., a school bus) is making a passenger stop or notice that the transit vehicle is attempting to merge and is requesting gap assistance. It includes an interface to the transit operator and the short range communications equipment that provides information to passing vehicles.False
Transit Vehicle Passenger Counting'Transit Vehicle Passenger Counting' collects transit vehicle loading data and makes it available to the center.False
Transit Vehicle Pedestrian Safety'Transit Vehicle Pedestrian Safety' exchanges current location and motion information with pedestrian–carried devices in the vicinity and uses that information to warn the driver of pedestrians in the vehicle's path. Information from on–board sensors (e.g., radars and image processing) are used to augment the short range communications, if available. In addition to notifying the driver, control information can also be provided to support automated control functions that can avoid the collision.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
Transit Vehicle V2V Safety'Transit Vehicle V2V Safety' exchanges current vehicle location and motion information with other vehicles in the vicinity, uses that information to predict vehicle paths, and notifies the driver when the potential for an impending collision is detected. Information from on–board sensors (e.g., radars and image processing) are used to augment the V2V communications, if available. In addition to notifying the driver, control information can also be provided to support automated control functions that can avoid the collision. This object is similar to the 'Vehicle Basic V2V Safety', but it accounts for crash scenarios that are unique to transit vehicles (e.g., Vehicle Turning Right in Front of Bus). It is also stop–aware since stop locations pose specific crash threats for transit vehicles. Finally, the detection and control algorithms, filters, and timing account for bus performance and risk profiles associated with remote vehicles that are unique to transit.False
Vehicle Basic Safety Communication'Vehicle Basic Safety Communication' exchanges current vehicle location and motion 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. Vehicle location and motion broadcasts are also received by the infrastructure and used by the infrastructure to support a wide range of roadside safety and mobility applications. 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 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
Vehicle Restricted Lanes ApplicationThe 'Vehicle Restricted Lanes Application' monitors and reports its own operating parameters and communicates with roadside equipment to safely enter, operate within, and exit restricted lanes that are relevant to all types of vehicles.False
