Connected Vehicle Roadside Equipment --> Personnel Device:
personnel safety warning

Definitions

personnel safety warning (Information Flow): Safety alerts and warnings provided to a personnel device. The provided information would identify safety threats (e.g., vehicle encroachment into a work area, personnel infringement into a travel lane)

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.

Personnel Device (Destination Physical Object): 'Personnel Device' represents devices used by emergency personnel or maintenance and construction personnel in the field. In the case of emergency personnel, the devices would include body cameras or smartphones (and their peripherals) that can be used by emergency personnel to provide images or video as well as send or receive data regarding the incident. The devices could also be used for incident scene safety messages to the personnel. In the case of maintenance and construction field personnel, the devices could be cellular phones or specialized safety devices that would be used for work zone safety messages to the personnel.

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: DEN Service - Local Unicast Wireless (EU)

Solution Description

This solution is used within Australia and the E.U.. It combines standards associated with EU: DEN Service with those for V-X: Local Unicast Wireless (EU). The EU: DEN Service standards include upper-layer standards required to implement V2x decentralized environmental notification information flows. The V-X: Local Unicast Wireless (EU) standards include lower-layer standards that support local-area unicast wireless solutions applicable to the European Union, such as G5, LTE, Wi-Fi, etc.

Information Flow Security

Rating Not Applicable High Low
Basis This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. A few false warnings should not have a bad consequence. When an emergency personnel receives a warning they can look around and verify whether or not a vehicle is actually headed towards them. However, a message saying it is safe when there is a car coming could lead to an emergency personnel not moving when they were in danger. It would be better to receive any messages than to not have this application available due to availability requirements. However, the higher the availability here, the more useful the application will be and the more emergency personnel can rely on it.
