Light Vehicle Basic Toll/Parking Payment'Vehicle Basic Toll/Parking Payment' includes the traditional on–board systems that pay for tolls and parking electronically. It includes the in–vehicle equipment that communicates with the toll/parking plaza and an optional interface to a carry–in payment device. See also 'Vehicle Payment Services', which provides a broader range of payment services.False
Light Vehicle Interactive Traveler Information'Light Vehicle Interactive Traveler Information' provides drivers with personalized traveler information including traffic and road conditions, transit information, maintenance and construction information, multimodal information, event information, and weather information. The provided information is tailored based on driver requests. Both one–time requests for information and on–going information streams based on a submitted traveler profile and preferences are supported.False
Light Vehicle Payment Service'Light Vehicle Payment Service' supports vehicle payments including VMT– and zone–based payments and payments for other services including fuel/charging services, tolls, and parking. To support VMT–based payment, this application tracks the location of the vehicle at specific times and reports this VMT data along with vehicle identification. A variety of pricing strategies are supported, including strategies that include credits or incentives that reward desired driving patterns and behavior. The onboard equipment supports secure short range communications with connected vehicle roadside equipment to support secure payments.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 Control Automation'Vehicle Control Automation' provides lateral and/or longitudinal control of a vehicle to allow 'hands off' and/or 'feet off' driving, automating the steering, accelerator, and brake control functions. It builds on the sensors included in 'Vehicle Safety Monitoring' and 'Vehicle Control Warning' and uses the information about the area surrounding the vehicle to safely control the vehicle. It covers the range of incremental control capabilities from driver assistance systems that take over steering or acceleration/deceleration in limited scenarios with direct monitoring by the driver to full automation where all aspects of driving are automated under all roadway and environmental conditions.False
Vehicle Control Warning'Vehicle Control Warning' monitors areas around the vehicle and provides warnings to a driver so the driver can take action to recover and maintain safe control of the vehicle. It includes lateral warning systems that warn of lane departures and obstacles or vehicles to the sides of the vehicle and longitudinal warning systems that monitor areas in the vehicle path and provide warnings when headways are insufficient or obstacles are detected in front of or behind the vehicle. It includes on–board sensors, including radars and imaging systems, and the driver information system that provides the visual, audible, and/or haptic warnings to the driver.False
Vehicle Environmental Monitoring'Vehicle Environmental Monitoring' collects data from on–board sensors and systems related to environmental conditions and sends the collected data to the infrastructure as the vehicle travels. The collected data is a byproduct of vehicle safety and convenience systems and includes ambient air temperature and precipitation measures and status of the wipers, lights, ABS, and traction control systems.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 Loading Zone Access'Vehicle Loading Zone Access' collects information on loading zone availability and makes this information available to the driver. It also provides the capability to reserve loading zone space prior to arrival.False
Vehicle Platoon Operations'Vehicle Platoon Operations' provides the capability for vehicles to operate in cooperative platoons with short fixed gaps and a designated lead vehicle. These capabilities are provided by systems on board the vehicle that coordinate with other vehicles and regulate acceleration and braking and provide higher–level functions that enable vehicles to join and depart from vehicle platoons.False
Vehicle Queue Warning'Vehicle Queue Warning' detects vehicle queues and reports queues to other vehicles using V2V communications and to the infrastructure using V2I communications. Vehicle–based queue warning builds on the exchange of vehicle location and motion and maneuvers that supports connected vehicle safety applications. This application also receives information about downstream queues using I2V communications. Individualized queue warnings and queue characteristics relevant to the vehicle are provided to the driver.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
Vehicle Situation Data Monitoring'Vehicle Situation Data Monitoring' is the highest–level representation of the functionality required to collect traffic and environmental situation data by monitoring and storing the experience of the vehicle as it travels through the road network. Collected data is aggregated into snapshots that are reported when communications is available and with flow control based on parameters provided by the infrastructure. Note that this functional object supports collection of data for areas remote from RSEs or other communications infrastructure.False
Vehicle Speed Management Assist'Vehicle Speed Management Assist' assists the driver in operating the vehicle within the current speed limit. It monitors current vehicle speed and communicates with the infrastructure to receive current speed limits and associated road configuration change notifications. Driver warnings are issued when unsafe or excessive speeds are detected based on the provided speed limits and current conditions.False
Vehicle Traveler Information Reception'Vehicle Traveler Information Reception' receives advisories, vehicle signage data, and other driver information of use to all types of vehicles and drivers and presents this information to the driver using in–vehicle equipment. Information presented may include fixed sign information, traffic control device status (e.g., signal phase and timing data), advisory and detour information, warnings of adverse road and weather conditions, travel times, and other driver information.False
