Definitions

personal crossing safety information (Information Flow): Current crossing status including permission to cross, crossing time remaining, and warnings (e.g., a vehicle's trajectory may impact non-motorized users including pedestrians and cyclists).

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

(None-Data) - Secure Wireless Internet (EU) (43)
(None-Data) - Secure Wireless Internet (ITS) (43)

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

Selected Solution

(None-Data) - Secure Wireless Internet (ITS)

Solution Description

This solution is used within Canada and the U.S.. It combines standards associated with (None-Data) with those for I-M: Secure Wireless Internet (ITS). The (None-Data) standards include an unspecified set of standards at the upper layers. The I-M: Secure Wireless Internet (ITS) 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 or IEEE 1609.2 certificates. A non-mobile (if any) endpoint may connect to the service provider using any Internet connection method.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

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
