Answer given by Mr Breton

on behalf of the European Commission

(7.6.2021)

Research shows that acoustic feedback is very effective[1]. To respond to concerns over risks of possible driver annoyance raised during the consultation on the draft Intelligent Speed Assistance (ISA) delegated act, the concept of cascaded acoustic warning[2] was introduced to minimise such risk. The cascaded acoustic warning is one of the four feedback technologies allowed by the proposed delegated act and is fully in line with the requirements under the General Safety Regulation (GSR)[3].

The Commission considers that 90% of road signs recognised represents an ambitious target[4]. It will also minimise the error rate under real driving condition as required by the legislation. The draft ISA delegated act was endorsed by the Member States Expert Group on 20 May 2021.

The Commission has proposed to review the performance of ISA systems, once they are deployed and real-world driving data is available, and to amend the draft ISA delegated act, if needed, by end of 2025. This date is well in advance of the overall review of the GSR[5]. Including at this stage phasing-out or phasing-in provisions would be premature and would prejudge the outcome of this assessment.

[2] If initial optical warnings are not followed by the driver (which is indicative of a driver having missed those warnings), an acoustic warning will sound for a few seconds maximum.

[3] Regulation (EU) 2019/2144 of the European Parliament and of the Council of 27 November 2019 on type-approval requirements for motor vehicles and their trailers, and systems, components and separate technical units intended for such vehicles, as regards their general safety and the protection of vehicle occupants and vulnerable road users (OJ L 325, 16.12.2019, p.1).

[4] The views of the stakeholders in the extensive consultation on the draft ISA delegated act were quite diverging on the performance rate for ISA (safety advocacy groups called for requiring ISA to recognize between 95 and 99% of all road signs, including the implicit signs, whereas car manufacturers argued that, due to technology constraints, between 50 and 70% recognition for limited explicit road signs should be required to avoid risk of false warning and driver annoyance).
