47. The expert from GTB presented driver assistance projections as a new feature of the adaptive driving beam with the aim to increase driver’s comfort and road safety (GRE-82-40). The presentation was accompanied by a live demonstration of three vehicles equipped with the new feature. To allow for the driver assistance projections, the expert proposed amendments to UN Regulations Nos. 48 and [149] (GRE-82-04, GRE-82-40).

48. GRE welcomed both GTB presentation and demonstration. Several experts were of the view that the new system could bring safety benefits provided that:

• Road projections symbols are standardized (e.g. according to UN Regulation No. 121).
• Road projections symbols do not distract other drivers.

Proposal to allow the projection of driver assistance symbols on the road ahead of the vehicle as part of the Adaptive Driving Beam (ADB).

23. The expert of GTB tabled a proposal which allowed for projection of driver assistance symbols on the road ahead of the vehicle, as part of the adaptive driving beam (ADB). This proposal was submitted in a package with an amendment to UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2020/4 and GRE-83-30). The expert from OICA presented supporting material for the proposal (GRE-83-33 and GRE-83-34), while the experts from Japan expressed concerns identified in the course of their own study (GRE-83-49). Other experts also expressed various views and concerns, such as the need for possible restrictions and standardization of the projected symbols, and that distraction must be avoided. Based on the comments received and pending further studies on the issue, GRE requested GTB to submit a revised document to the next session and invited all interested parties to contribute. Meanwhile, GRE asked the expert from Finland to liaise with the Working Party on General Safety Provisions (GRSG) which had established a Task Force on Field of Vision Assistant.
