Advanced Driver Assistance Systems (ADAS) are becoming more common in vehicles. These technologies represent important advances in vehicle safety and it is crucial to optimize their potential. At the same time, ADAS design and technology is evolving rapidly, so standard specifications do not exist yet for their design and performance.
In ADAS, warning and control each have an important role to play for safety enhancement. Effective warning has a potential of compensating for the known limitations of drivers and thus preventing road trauma. This document is therefore intended to provide a set of recommendations to be observed by the designers and manufacturers of ADAS with regard to imminent warnings for driver assistance purposes.
Regarding the characteristics of warnings, no common policies exist at the moment for their design. Meanwhile, there is concern that drivers might be confused by the presence of various types and permutations of warning systems on the market. Consequently, we recognise the importance and the need for a global approach rather than multiple different local solutions.
This document was prepared by the IHRA working group on Intelligent Transport Systems (ITS) to support the activities of the UNECE WP.29 ITS informal group. While hoping that the document will be used widely for the design and manufacture of warning systems, IHRA also recognizes that it is the UNECE WP.29 who will decide on utilization methods of this document on the basis of recommendations from its ITS informal group.
Finally, some advanced safety technologies have already been commercialized, but many are still under development. Consequently, we have a good opportunity to lay down principles and guidelines in a manner that should not hinder advances in technologies; rather it should encourage the research and development of warning system assessment methods, including testing procedures and performance measures.
