Breakout Session #1

Reading the Road Ahead: Traffic Control Devices and Machine Vision Interactions

Monday, July 9, 1:30 PM – 5:30 PM
Room: Yosemite A


  • Scott O. Kuznicki, P.E., Director of Safety and Mobility Technology Solutions, Transpo Group
  • Brian Watson, Director of New Programs, American Traffic Safety Services Association

Session Description

The 2017 workshop uncovered efforts road authorities are making as they prepare to achieve a high degree of compliance with the functional needs machine vision equipment. Participants discussed consistency in traffic control devices and geometric design, cloud-supported mapping services, and international efforts to harmonize approaches to machine vision compliance despite poor participation from machine vision suppliers.

Determining the suitability of roadway segments for AV operations will aid developers, suppliers, vehicle manufacturers, users, and road network owners and operators. This understanding of the interaction between machine vision systems and the roadway environment will be a critical component of agency planning for autonomous vehicle deployments.


  • Identify Key Failure Modes of Machine Vision Related to TCDs and Infrastructure
  • Identify Key Interactions Between TCDs and Machine Vision Systems
  • Synthesis of Practice Statements for Roadway Rating Systems to Determine Road State Relative to Machine Vision Capabilities

Correlating Machine Vision Performance and Operating Design Domain: Research Problem Statements for Road Rating Systems

  • Moderated by Scott Kuznicki and Brian Watson

This workshop will build on the AVS 2017 work and the workshop to continue development of a framework for implementing a road assessment system and information clearinghouse. Continuing last year’s work, participants will develop a capabilities matrix for machine vision systems and, based on this, develop a corresponding framework for research in the form of TRB Research Problem Statements that will lead to recommendations for roadway readiness based on TCD applications and condition.
