UN Regulation No. 157 was the first to establish worldwide uniform provisions for the type-approval of SAE Level 3 (L3) Automated Driving Systems (ADS) called Automated Lane Keeping Systems (ALKS). To ensure the safety of the systems, detailed test provisions were introduced, which include mandatory public road tests. The present work is focusing on public road testing and safety assessment of ALKS systems and reports on the methodology, challenges and lessons learned from a proof-of-concept experimental campaign. In line with the regulatory requirements concerning the minimum duration of system verification on public roads, various traffic circumstances and mandatory traffic scenarios were all considered in carrying out the experimental campaign. Since there was no suitable ADS on the market, a vehicle equipped with an SAE L2 system was used instead. The effort was aimed at providing a practical proof of concept for the regulatory provisions and not verifying the compliance of the vehicle under test. By carefully planning test execution, the authors managed to encounter the required traffic density conditions in all needed traffic scenarios with their necessary repetition number, within four testing days. In conclusion, the experimental campaign put in place under UN R157 proved to be a feasible exercise.
