Physical Object: Multi-Access Edge Computing
MEC Traveler Information Communications
Overview
'MEC Traveler Information Communications' distributes information to vehicles for in-vehicle display. The information may be provided by a center (e.g., variable information on traffic and road conditions in the vicinity of the field equipment) or it may be determined and output locally (e.g., static sign information and signal phase and timing information). This includes the interface to the center or field equipment that controls the information distribution and the wireless communications equipment that provides information to vehicles.
This functional object is included in the "Multi-Access Edge Computing" physical object.
This functional object is included in the following service packages:
- PT12: Transit Vehicle at Station/Stop Warnings
- TM16: Reversible Lane Management
- TM17: Speed Warning and Enforcement
- TM22: Dynamic Lane Management and Shoulder Use
This functional object is mapped to the following Functional View PSpecs:
- 1.1.1.6: Collect Vehicle Roadside Safety Data
- 1.1.2.6: Process Collected Vehicle Safety Data
- 1.2.7.3.1: Process In-vehicle Signage Data
- 1.2.7.3.2: Process Vehicle Safety and Environmental Data for Output
- 1.5.10: Collect Vehicle Emissions Messages
- 6.7.3.3: Provide Short Range Traveler Information
- 9.2.3.8: Collect Connected Vehicle Field Equipment Status
- 9.3.3.5: Manage Speeds at Roadside
Requirements
| # | Requirement |
|---|---|
| 01 | The field element shall provide data about transit vehicle movement to approaching vehicles. |
| 02 | The field element shall distribute advisory information, such as evacuation information, wide-area alerts, incident information, work zone intrusion information, recommended speed limit and other special information to passing vehicles using short range communications, under center control. |
| 03 | The field element shall receive transit vehicle movement information. |
| 04 | The field element shall distribute indicator and fixed sign information, including static sign information (e.g., stop, curve warning, guide signs, service signs, and directional signs) and dynamic information (e.g., current signal states and local conditions warnings identified by local environmental sensors) to equipment on-board vehicles under center control. |
| 05 | The field element shall receive dynamic signage information. |
| 06 | The field element shall return system operational status to the controlling center. |
| 07 | The field element shall distribute the location, duration, and operating parameters for lanes that are reserved. |
