Lane Assist systems do not always function the way they should. ANWB and Royal HaskoningDHV carried out a road test with four different car models and a questionnaire answered by approximately 100 car drivers, ANWB members, using Lane Assist systems. The problems are not always originating from the system itself, but conditions surrounding use of the car, such as information to end-users on expectations of the system.
Drivers tend to overestimate the accuracy of these systems, as they use the Lane Assist functions without sufficient information on its limitations. This lack of knowledge means risks to traffic safety, because tests on the road revealed the system does not recognise road markings under all circumstances. This is mostly due to a reduced visibility of the road markings, which leads to the car not reading the road and not supporting the driver as intended. The system not being flawless combined with drivers who overestimate the Lane Keeping capacity can lead to a decrease in traffic safety. The research of ANWB and Royal Haskoning leads to some recommendations to improve safe usage of the systems.
