Task force in-session amendments to the proposal to amend para. 0. to introduce provisions for vehicles of category Y and Automated Driving Systems, amend para. 1.4. to exclude category Y vehicles and exempt certain category N₁ vehicles, add sentences to paras. 2.8., 2.22., 2.29., 2.32., 2.45. defining or clarifying applicability for category Y vehicles, amend para. 2.44. to define windscreen test area for category Y vehicles without windscreens, and replace language in para. 5.3.1.2. to refer to active ADS rather than ADS performing the Dynamic Driving Task.

Safety Performance Indicators (SPIs) are measurable metrics monitoring and evaluating ADS safety in operation, including lagging indicators recording outcomes like crashes and injuries, and leading indicators capturing precursors like near misses and risky behaviours. Research tested time-based and distance-based SPIs on the SHRP2 dataset containing 1402 crashes and 5262 near-crashes, achieving Area Under the Curve values of 0.883 for Distance Headway and 0.832 for Time-to-Collision in distinguishing crashes from normal driving. SPIs support safety cases, in-service monitoring and reporting requirements, and continuous ADS deployment monitoring, with future work extending analysis to additional datasets and field data collection.
