Project Details: NMDOT CV Queue Warning


PROJECT OVERVIEW

Project Name:

Project Details: NMDOT CV Queue Warning

Description:

The Connected Vehicle Queue Warning (Q-WARN) application utilizes connected vehicle technologies, including vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communications, to enable vehicles within the queue event to automatically broadcast their queued status information (e.g., rapid deceleration, disabled status, lane location) to nearby upstream vehicles and to infrastructure-based central entities (such as the TMC).

FUNCTIONAL REQUIREMENTS

Click on a Project Inventory element from the list above to view functional requirements.

Roadway Safety Warning System

  • The field element shall collect safety data from passing vehicles including location, vehicle motion (speed, heading, acceleration), vehicle control (brakes, steering, throttle, exterior lights), and additional vehicle status (anti-lock brake activation, stability control activation).
  • The field element shall provide warnings to passing vehicles using field-vehicle communications.
  • The field element shall support remote monitoring and control by an authenticated center.

Vehicle Warning System

  • The vehicle shall provide its location, speed, direction, and other information to field elements.
  • The vehicle shall receive warnings from field elements.
