Connected Vehicle Roadside Equipment --> Commercial Vehicle OBE:
intersection status
Definitions
intersection status (Information Flow): Current signal phase and timing information for all lanes at a signalized intersection. This flow identifies active lanes and lanes that are being stopped and specifies the length of time that the current state will persist for each lane. It also identifies signal priority and preemption status and pedestrian crossing status information where applicable.
Connected Vehicle Roadside Equipment (Source Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices (i.e., Roadside Units (RSUs)) equipped with short range wireless (SRW) communications technology, as well as any other supporting equipment that leverage the RSU and are not described by other objects (e.g., a local roadside processor). CVRSE are used to send messages to, and receive messages from, nearby vehicles and personal devices equipped with compatible communications technology. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.
Commercial Vehicle OBE (Destination Physical Object): The Commercial Vehicle On-Board Equipment (OBE) resides in a commercial vehicle and provides the sensory, processing, storage, and communications functions necessary to support safe and efficient commercial vehicle operations. It provides two-way communications between the commercial vehicle drivers, their fleet managers, attached freight equipment, and roadside officials. A separate 'Vehicle OBE' physical object supports vehicle safety and driver information capabilities that apply to all vehicles, including commercial vehicles. The Commercial Vehicle OBE supplements these general ITS capabilities with capabilities that are specific to commercial vehicles.

| Basis | This data is intended for all vehicles in the immediate area of the sender. | If this is compromised, the Vehicle OBE will receive messages that are inconsistent with what the traffic signals are displaying. This could lead to confusion and reduce the ability of the application to provide value. | If this is down, the Vehicle OBE doesn't get the information it needs to stay in synch with the actual signal state, reducing or eliminating the value add from having this application. We assume that the Vehicle OBE will detect a lack of availability and choose not to send out-of-date information, so a failure of availability cannot have worse consequences than a failure of integrity which we have previously assessed at MEDIUM. | |
