Connected Vehicle Roadside Equipment --> Micromobility Vehicle OBE:
intersection geometry

Definitions

intersection geometry (Information Flow): The physical geometry of an intersection covering the location and width of each approaching lane, egress lane, and valid paths between approaches and egresses. This flow also defines the location of stop lines, cross walks, specific traffic law restrictions for the intersection (e.g., turning movement restrictions), and other elements that support calculation of a safe and legal vehicle path through the intersection.

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.
