Advanced driver support systems and screen interfaces in cars - How do they affect driver behaviour?

Advanced driver assistance systems in cars (ADAS) can contribute to smoother speed, safer distance to the car in front, improved situational awareness, and reduced mental strain in certain contexts. On the other hand, ADAS can increase the chance of performing secondary tasks while driving, reducing the focus on driving. ADAS can also contribute to increased reaction time, lack of reaction, or incorrect reaction, in critical situations because the driver takes a less active part in driving, or has an excessive trust in the system; as well as impairment of manual driving skills due to prolonged use. Knowledge of the use of ADAS and integrated screens in cars is insufficient. Further research should focus on: older drivers, use and design of heads-up displays (HUD), familiarity with, use (including mental load and distraction) and training of ADAS, and use of voice control. A scheme for studying parts of this is presented in the last part of the report.
