Multi-Access Edge Computing --> Micromobility Vehicle OBE:
intersection geometry

This flow may also be implemented by 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.

Multi-Access Edge Computing (Source Physical Object): 'Multi-Access Edge Computing' ((MEC) previously known as mobile edge computing) represents computing devices that operate and are managed like a cloud server, but are deployed at the edge of a network (typically a cellular network, but it could be any network). While not in strict proximity to the transportation network, these systems do benefit from vastly decreased distances to the roadway compared to central systems, and so can provide lower latency than strictly backoffice systems

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.

Communication Solutions

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

EU: Signal Control Messages - Secure Wireless Internet (EU)

Solution Description

This solution is used within Australia and the E.U.. It combines standards associated with EU: Signal Control Messages with those for I-M: Secure Wireless Internet (EU). The EU: Signal Control Messages standards include upper-layer standards required to implement signal control information flows. The I-M: Secure Wireless Internet (EU) standards include lower-layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 certificates. A non-mobile (if any) endpoint may connect to the service provider using any Internet connection method.

Basis Map data intended for general use by any C-ITS component than needs it. No information here includes PII or anything else that, if viewed by someone other than the participant, would lead to harm. Map data is used for a host of application purposes. This widespread use means that any corruption in the data has a widespread and far reaching effect. Occasional outages of this flow will delay updates and lead to a loss of accurate function of some applications. Depending on the application this could be HIGH.
