Preparing pavement markings for AV and ADAS Machine Vision Systems

Tuesday, June 10, 2025
4:45 PM – 6:00 PM MT
Abstract: The significant challenge underway in the US and abroad is the transition of the vehicle fleet from legacy vehicles with human drivers where the only interaction between the vehicle and roadway is where the tire and roadway touch, to a quickly developing era with vehicles driven by humans with conveniences and safety features that assess the road to provide travel more efficient and safer.

By 2025, there will be approximately 75 million vehicles in the US equipped with ADAS including Camera (Machine Vision) systems reading the road ahead to provide automated vehicle safety features. Of all the objects that the camera based systems are trained to recognize (vehicles, pedestrians, roadway debris, roadway assets, etc.), pavement markings are always on the top of the list in the roadway asset category.

In 2022 the FHWA Mandatory Minimum Pavement Retroreflectivity Requirements came into force 6th September 2026. This welcome update to the Manual on Uniform Traffic Control Devices (MUTCD) will play a key role in reducing transportation-related fatalities and serious injuries. The ruling will also help to support the operation of Autonomous Driver Assisted Systems (ADAS) that are increasingly dependent on high quality longitudinal pavement markings to operate correctly.

Research is starting to demonstrate that human drivers and vehicle-based Machine Vision systems such as ADAS (Advanced Drive Assisted Systems) i.e., “Lane -Keep- assist” & “Lane Departure warning” systems) all need good quality pavement markings in order to operate safely & efficiently. Depending upon the road user type (human versus machine vision), these needs are different. This abstract will explore the needs of human drivers and ADAS Machine Vision technologies differ and how new pavement marking assessment technologies can assist agencies with road readiness for these vehicle technologies & also be compliant with the MUTCD Mandatory Minimum Pavement Retroreflectivity Requirements

Learning Objectives:

Attendees can expect to learn the following from this session:
  • Illustrate from previous and on-going research to show the different needs between human and ADAS machine vision requirements.
  • Introduce some new criteria for pavement markings that would provide safer operating conditions for vehicle-based MV systems (ADAS)
  • Propose possible solutions on how road readiness of pavement marking condition can be assessed to assist agencies with this transition the introduction of Machine Vision systems
  • Understand the implications of the MUTCD mandatory retroreflectivity requirements for pavement markings and how to implement a maintenance plan before 2026 deadline & possible solutions to meet these requirements..
