Connected Vehicle Roadside Equipment --> Micromobility 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 that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. 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.
Micromobility Vehicle OBE (Destination Physical Object): The Micromobility Vehicle On-Board Equipment (MMV OBE) provides the vehicle-based sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. The MMV OBE includes general capabilities that apply to bicycles and other low-powered mobility devices such as e-scooters, powered wheelchairs, and power assisted bicycles. The MMV OBE includes the common interfaces and functions that could apply to any low-powered mobility device. The radio(s) supporting V2V and V2I communications are a key component of the MMV OBE. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Advanced sensors, processors, and enhanced traveler interfaces (through PIDs), complement traveler information services so that, in addition to making informed mode and route selections, the vulnerable road user travels these routes in a safer and more consistent manner.

Basis | This data is intended for all vehicles in the immediate area of the sender. | info needs to be accurate and should not be tampered so the vehicle OBE has correct SPaT info for all lanes; however the driver can still see the traffic signals. From NYC: This information will be used by the vehicle ASD to determine whether or not to issue a red light violation warning to the driver. False information could lead to the vehicle ASD not issuing a warning when in fact it should have. The vehicle operator is not using this information to decide whether or not to travel through the intersection. They will still have visual cues, such as traffic lights, indicating whether or not they can travel through the intersection. | needs to be available so the vehicle OBE has correct SPaT info; identifies signal priority and preemption status and pedestrian crossing status information, etc. However availability cannot be guaranteed over a wireless medium. From NYC: Without this information, vehicle ASD may not properly issue a red light violation warning to the driver. The vehicle operator will still use the traffic |
