Status of ITS/AD Informal Group consideration of guidance for WP.29 working parties on the regulation of automated driving technologies, especially concerning automatically commanded steering under UN R79.

This proposal aims to align the UN Regulation 106 with international standards (ETRTO, T&RA and ISO 4351-2 table 2). This proposal will also avoid any possible misunderstanding for the application of the EC Regulation 167/2013 that refers to UN R106.

This proposal is an alternative to that represented in document GRRF/2015/9 and GRRF-79-19.

European countries are considering new requirements to require the fitment of snow tyres for use in severe snow conditions on specific axles of heavy duty vehicles. New tyres are approved under UN R117; however, a large percentage of heavy duty vehicles are fitted with retreaded tyres which are outside the scope of UN R117. This proposal would transpose the relevant requirements for new snow tyres into UN R109 in order of avoid the exclusion of retreaded tyres from such applications/markets.

The overall aim of the study is to propose policy options concerning the use of tyres for improvement of traffic safety. Centrally to this, is the idea that end users need to make the correct assessment in relation to the tyre condition in order to achieve a level of safety as high as possible. Within this context, the tyre condition is considered in relation to technical elements (tyre inflation pressure, tyre tread depth, tyre damage, tyre age, and meteorological influences) and one information element (driver awareness). The study addresses the topics of tyre usage and the impact on road safety (which are the potential safety improvements related to tyre usage from a technical perspective) and how can road users be supported to use tyres that have a better safety performance by policy options.
