Multi-Access Edge Computing --> ITS Roadway Equipment:
detected unequipped vehicles and VRUs

This triple is bi-directional. See also ITS Roadway Equipment --> Multi-Access Edge Computing: detected unequipped vehicles and VRUs
This flow may also be implemented by Connected Vehicle Roadside Equipment --> ITS Roadway Equipment: detected unequipped vehicles and VRUs

Definitions

detected unequipped vehicles and VRUs (Information Flow): Notification of a nearby vehicle (light vehicle, commercial vehicle, MMV etc.) or vulnerable road user that does not appear to be equipped with a short range communications device but is detectable using onboard vehicle or infrastructure sensors. The flow communicates detected vehicle/VRU location, physical characteristics, observable kinematics and confidence in those measures.

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

ITS Roadway Equipment (Destination Physical Object): 'ITS Roadway Equipment' represents the ITS equipment that is distributed on and along the roadway that monitors and controls traffic and monitors and manages the roadway. This physical object includes traffic detectors, environmental sensors, traffic signals, highway advisory radios, dynamic message signs, CCTV cameras and video image processing systems, grade crossing warning systems, and ramp metering systems. Lane management systems and barrier systems that control access to transportation infrastructure such as roadways, bridges and tunnels are also included. This object also provides environmental monitoring including sensors that measure road conditions, surface weather, and vehicle emissions. Work zone systems including work zone surveillance, traffic control, driver warning, and work crew safety systems are also included.

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

(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.

InteroperabilityDescription
LocalIn cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides.

Security

Information Flow Security
  Confidentiality Integrity Availability
Rating Moderate High Moderate
Basis This data is intended to be shared with all nearby vehicles, traffic control devices and vulnerable road users; it is essentially public. However, all communications between field infrastructure should be protected from viewing to prevent attackers from analyzing traffic and developing attack methods. This data may be used as input to vehicle situational awareness and thus trigger crash-avoidance actions. If manipulated or incorrect, a crash may occur; though vehicles able to use this data also have sensory capabilities, this flow will often contain data describing objects/vehicles/VRUs that are obscured and not observable by on-board sensors. This data may be used as input to vehicle situational awareness and thus trigger crash-avoidance actions. This data enable collision avoidance actions that are impractical without it, as vehicles able to use this data to sense-by-proxy other vehicles/VRUs/obstacles that are obscured by on-board sensors. Considered MODERATE and not HIGH only because the lack of availability reverts to existing operations and does not actively make safety worse.
