Proposal to increase the usability and safety of the ELKS and to align the technical requirements with technological progress:

• Ensure that an ELKS is not adversely affected by magnetic or electrical fields
• Clarify when the system shall automatically deactivate to prevent unintended consequences, which should be at least detailed in the vehicle’s operating instructions as a minimum
• Include dashed lane markings for CDCF and road edges for ELKS, ensuring all systems fitted meet the highest safety standards and utilise the latest technology to prevent unintended lane departures 1
• Include the latest lane markings located in Annex 3 to UN Regulation 130. This is important as the 01 series of amendments to UN Regulation 130
  includes Australian lane markings, ensuring compatibility
• Eliminate the option for an acoustic warning for LDWS to reduce confusion with the CDCF intervention acoustic warning required in paragraph 6.6.4.
• Correct minor grammatical errors
• Enhance usability by establishing system response limits, where recent research has highlighted the prevalence of consumers turning these lifesaving systems off
• Ensure consistent and repeatable testing.

Proposal to reinstate the obligation for the granting approval authority to inform the approval authority of each of each Contracting Party in whose territory the manufacturer intends to deploy the ALKS pending approval before granting the approval (according to Annex 1–Appendix 2).

Proposal to require the approval authority to upload information received from the manufacturer concerning remedial action(s) addressing an ALKS design to the DETA platform and to clarify the use of DETA with regard to ALKS approved under UN R157.

The draft document identifies potential research questions for ACPE (Acceleration Control for Pedal Error) systems across three categories: basic data collection on system specifications and cost-benefit analysis; performance requirements and test procedures; and human factors analysis.
