Text prepared by the Informal Working Group on Awareness of Vulnerable Road Users proximity in low speed manoeuvres (VRU-Proxi) to establish a new UN Regulation on Blind Spot Information Systems (BSIS) intended to be fitted to heavy goods vehicles.

Revised version of document GRSG/2018/24 as adopted by GRSG during its 115th session.

Password protected file: ISO/CD 19206-4: Road vehicles — Test devices for target vehicles, vulnerable road users and other objects, for assessment of active safety functions — Part 4: Requirements for bicyclist targets. The proposed new UN Regulation on Blind Spot Information Systems refers to this standard presently under development within ISO. The GRSG secretariat controls access to the working party participants.

Proposal to define the scope of the new regulation as vehicles of categories N₂ > 8 t and N₃. The proposal argues against inclusion of M₂ and M₃ vehicles.

Proposal to remove ambient light constraints (e.g., 1000 lux threshold) from the draft blind spot information systems text.

Proposal to increase the 0.25 m gap between the vehicle and the bicycle to 0.50 m in order to avoid excessive false positive warnings.

Proposal to explicitly reference consideration of the time to collision in assessing the blind spot detection system performance.
