Intersection Movement Assist
The Intersection Movement Assist (IMA) application warns the driver of a vehicle when it is not safe to enter an intersection due to high collision probability with other vehicles at stop sign controlled and uncontrolled intersections. This application can provide collision warning information to the vehicle operational systems which may perform actions to reduce the likelihood of crashes at the intersections.

Includes Enterprise Objects:
Enterprise Object | Description |
---|---|
Application Certification Entity | The body that determines whether an application may be deployed and operated in the Connected Vehicle Environment. This entity's composition, the requirements it applies and the procedures it uses to verify those requirements may vary with application type. For example, applications with human safety component (crash avoidance, movement assistance etc.) may have stringent requirements and extensive testing in a variety of conditions, while applications that provide strictly mobility functionality may have far less testing requirements; possibly as little as just making sure the application doesn't interfere with any other applications. |
Device Certification Entity | The body that determines whether a device may be deployed and operated in the Connected Vehicle Environment. This entity's composition, the requirements it applies and the procedures it uses to verify those requirements may vary with device type. |
Driver | The 'Driver' represents the person that operates a vehicle on the roadway. Included are operators of private, transit, commercial, and emergency vehicles where the interactions are not particular to the type of vehicle (e.g., interactions supporting vehicle safety applications). The Driver originates driver requests and receives driver information that reflects the interactions which might be useful to all drivers, regardless of vehicle classification. Information and interactions which are unique to drivers of a specific vehicle type (e.g., fleet interactions with transit, commercial, or emergency vehicle drivers) are covered by separate objects. |
Federal Regulatory | Federal regulatory bodies that have legal authority to control and/or provide input to policies regulating transportation infrastructure and operations. This includes entities such as the Federal Communications Commission and US Department of Transportation. |
Remote Vehicle OBE Owner | The owner of the Remote Vehicle OBE |
State Regulatory | State regulatory bodies that have legal authority to control and/or provide input to policies regulating vehicles, transportation infrastructure and operations. This includes entities like Departments of Motor Vehicles, property tax authorities and tolling agencies. |
Vehicle Basic Safety Installer | Application Component Installers are specified more by role than by function. Installers are responsible for the installation of the application component, which may require a support system, and may entail agreements and relationships between end users and application providers. |
Vehicle Basic Safety Maintainer | Application Component Maintainers are specified more by role than by function. Maintainers are responsible for the maintenance (configuration changes, patches and updates, hardware repairs) of the application component, which may require a support system, and may entail agreements and relationships between end users and application providers. |
Vehicle Basic Safety Provider | Application Component Providers are specified more by role than by function. Providers are responsible for the development of the application component, including initial creation, enhancement and bug fixes. Delivery of the application to the end user may require relationships with other entities (installers, maintainers) if the provider chooses not to fulfill those roles. |
Vehicle Manufacturer | The entity that builds, assembles, verifies and validates the Vehicle in which the Vehicle OBE will eventually operate. |
Vehicle OBE Manufacturer | The entity that builds, assembles, verifies and validates the Vehicle OBE. This can be an OEM-equipped OBE, retrofit or aftermarket equipment. |
Vehicle OBE Owner | The entity, individual, group or corporation that owns the Vehicle On-Board equipment. This could be the same as the Vehicle Owner, but it could be a third part that licenses the use of the OBE to the Owner. |
Vehicle Owner | The individual, group of individuals or corporate entity that is identified as the registered owner of the Vehicle under state law. |

Remote Vehicle OBEs | 'Remote Vehicle OBEs' represents other connected vehicles that are communicating with the host vehicle. This includes all connected motorized vehicles including passenger cars, trucks, and motorcycles and specialty vehicles (e.g., maintenance vehicles, transit vehicles) that also include the basic 'Vehicle OBE' functionality that supports V2V communications. In CVRIA, this object provides a source and destination for information transfers between connected vehicles. The host vehicle on-board equipment, represented by the Vehicle OBE physical object, sends information to, and receives information from the Remote Vehicle OBEs to model all connected vehicle V2V communications in CVRIA. |
Vehicle | The conveyance that provides the sensory, processing, storage, and communications functions necessary to support efficient, safe, and convenient travel. These functions reside in general vehicles including personal automobiles, commercial vehicles, emergency vehicles, transit vehicles, or other vehicle types. |
Vehicle Basic Safety | "Vehicle Basic Safety" 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. |
Vehicle Databus | The 'Vehicle Databus' represents the interface to the vehicle databus (e.g., CAN, LIN, Ethernet/IP, FlexRay, and MOST) that may enable communication between the Vehicle OBE and other vehicle systems to support connected vehicle applications. The vehicle system statuses and/or sensor outputs available on the databus will vary based on the equipment installed on the vehicle and availability on databus. System statuses and sensor outputs may include select vehicle systems and sensors such as accelerometers, yaw rate sensors, and GPS derived location and timing information. In CVRIA, this physical object is used to represent the onboard interactions between the Vehicle OBE and the other systems included in a host vehicle. Note that the vehicle databus interface is not standardized across all vehicle classes. Also, some Vehicle OBE implementations will not have access to the vehicle databus. See 'Vehicle OBE' for more information. |
Vehicle OBE | The Vehicle On-Board Equipment (OBE) provides the vehicle-based processing, storage, and communications functions necessary to support connected vehicle operations. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle OBE. This communication platform is augmented with processing and data storage capability that supports the connected vehicle applications. In CVRIA, the Vehicle OBE includes the functions and interfaces that support connected vehicle applications for passenger cars, trucks, and motorcycles. Many of these applications (e.g., V2V Safety applications) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle OBE includes the common interfaces and functions that apply to all motorized vehicles. |
