Connected Vehicle Roadside Equipment --> Micromobility Vehicle OBE:
personal crossing safety information
Definitions
personal crossing safety information (Information Flow): Current crossing status including permission to cross, crossing time remaining, and warnings in the event that a vehicle reports an imminent intersection infringement that may impact non-motorized users including pedestrians and cyclists.
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.
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 intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. | People will use this information to determine if they can cross, so incorrect information increases the risk of accidents. DISC: THEA believes this to be HIGH: "info needs to be accurate and should not be tampered with (used to warn pedestrians of infringement, etc.); higher because enables accessibility; pedestrians may not be able to see/hear the information" | If this is down, the pedestrian still gets information from the RE and from the rest of the environment. DISC: NYC and THEA believe this to be MODERATE: info needs to be accurate and should not be tampered with (used to warn pedestrians of infringement, etc.); higher because enables accessibility; pedestrians may not be able to see/hear the information; however, overall I level is M, not H, because message is still just information and pedestrian needs to use their own awareness A: needs to be readily available to give permission to cross, time remaining, etc. but cannot guarantee wireless communication; however, worst case is the pedestrian has to wait; also cannot guarantee wireless communication |
