|---|
| 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 |

These capabilities are provided by systems on board the vehicle that coordinate with other vehicles and control acceleration and braking. In advanced implementations, the capability to coordinate with the infrastructure to support more advanced clustering strategies and use infrastructure provided target speed and traffic control information to improve performance. | False |

It provides the local user interface through which a user can specify and manage subscriptions. It supports different mechanisms for collecting data for the end–user including one–time query–response as well as publish–subscribe services. | False |
|---|
| Vehicle Electric Charging Assist | 'Vehicle Electric Charging Assist' uses short range communications to coordinate with electric charging stations, providing information about the operational state of the electrical system, the maximum charge rate, and the percentage–complete of the charge. This application also receives current information about electric charging systems in the region and makes this information available to the driver on request. | False |
|---|
| Vehicle Emergency Notification | 'Vehicle Emergency Notification' provides the capability for drivers or collision detection sensors to report an emergency and summon assistance. It gathers data from on–board collision detection sensors, provides a mechanism for the driver to summon assistance, and includes a communications capability to report the collision including indicators of collision severity, the number of passengers involved, and information about the vehicle that may affect the response. | 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 Gap Assist | 'Vehicle Gap Assist' uses V2I communications to collect traffic gap information and associated alerts and warnings that are displayed to the driver who is navigating a stop–sign controlled intersection with a major road. | False |
|---|
| Vehicle Interactive Traveler Information | '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 |
|---|
| 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 |
