The Automated Vehicle Safety Consortium (AVSC) announced the availability of its fourth published best practice titled, Data Collection for Automated Driving System-Dedicated Vehicles (ADS-DVs) to Support Event Analysis. This best practice recommends thirty-nine data elements to be collected for SAE Level 4 and Level 5 automated driving systems (ADS).

When an ADS takes the place of a human driver, new considerations are introduced related to sensing, processing, and control systems. Data collection becomes even more important for event reconstruction and analysis of critical driving scenarios.

An event is a collision or collision-like situation. Existing methods used to determine human inattention, disobeyed traffic controls and attempted avoidance maneuvers may be insufficient to determine factors related to AV control systems and saliency. The new data collection best practice supports producing lessons learned for AV events. Specific recommended data elements should do the following:

  1. Provide information about what the AV “saw” and “did”, and;
  2. Help identify the technology-relevant factors that contributed to the event.
