GRVA-1 agreed to reconsider based upon a formal document at GRVA-2 taking into account particularly concerns over the impact of the filtering change on tolerances and interpretation of results.

53. The expert from France introduced GRVA-01-38 (based on GRRF-86-13) addressing the accuracy of interpretation of data produced during system assessment. The expert from Germany welcomed the document and proposed to consider the filtering provisions together with the tolerances. Other experts welcomed the document and agreed to study it until the next session. GRVA agreed to resume consideration of this item at its January 2019 session.

Outcomes from the discussion of the proposal from France to clarify requirements of the optical signal for a CSF intervention to ensure sufficient flashing tell-tale visibility for the driver, to specify the duration of such ACSF signals, to ensure a safe hierarchy of signals (e.g., ESF over CSF) by priority, to clarify that deactivation when departing an ODD means the “off mode”, and to add a cross-reference pointing to paragraphs that define cases of manual and automatic deactivation.
