Night-Vision Display Unlit during Uneventful Periods May Improve Traffic Safety

摘要: It is always uncertain if a new assistance system will enhance traffic safety or not: empirical studies indicate that driving style may deteriorate when the driver experiences increased margin created by an advanced system. To minimize this negative effect on style, we redesigned night vision so it appeared differently to driver: let system's head-up display be turned off during operation, lit up only detected obstacle (e.g., pedestrian animal) road ahead. This presentation was compared in simulator study traditional solution of constantly lit-up display. The results drivers reacted more reliably (showed less variance reaction times) using system, which implies lighting IR-display constituted effective warning. Also, greater extent drove at normal (slower) speeds re-designed More generally, systems offering discontinuous support (i.e. critical situations) have as their presence not felt vividly driver.
