The proposal opens the opportunity to project driver assistance symbols on the road ahead the vehicle as part of the Adaptive Driving Beam by introducing angular limits for the placement of these projections as well as luminous intensity limits in order to guarantee a good perceptibility of the symbols for the driver at night time without distracting other road users.

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.
