Road traffic in South Africa presents some very special challenges: different road surfaces, wildlife on rural roads and many pedestrians in the city as well as in the interurban traffic who often cross lanes completely unexpectedly. Automated and autonomous vehicles have to be aware of these peculiarities and respond in a reliable manner. In the fourth leg of the Mercedes-Benz Intelligent World Drive, the test vehicle - based on the current S-Class series-production saloon - is facing up to South Africa's idiosyncrasies with automated test drives on the roads of the Western Cape and in the city of Cape Town. Mercedes-Benz started the Intelligent World Drive at the Frankfurt International Motor Show (IAA) in September to adapt more highly automated driving functions to national traffic and user practices. The aim is to gather global insights into real-life traffic conditions for the advancement of the technologies. As part of this, up until January 2018 the test vehicle is collecting comprehensive information in a variety of complex traffic situations on five continents and in doing so is sounding out the limitations of the current systems. The focus of the test drives on the Western Cape is on pedestrian detection in many unfamiliar situations in particular, both in dense city traffic as well as on rural roads. Furthermore, the test vehicle based on the S‑Class is collecting information for detecting road signs specific to the country, validating the digital map material of HERE MAPS and testing out a prototype of the innovative light system DIGITAL LIGHT.
