“…This suggests that, as drivers gain experience and trust in ACC, mind wandering rates may come to align with those found when driving manually. Increased trust of ACC may even cause users to overrely on the technology (Kovordányi et al, 2005), such that mind wandering rates and the associated reductions in driving performance would come to exceed those found among manual drivers. The lack of variability in experience using ACC among the participants in the current study prevented empirical assessment of this issue.…”

Objective This field study examined the effects of adaptive cruise control (ACC) on mind wandering prevalence. Background ACC relieves the driver of the need to regulate vehicle speed and following distance, which may result in safety benefits. However, if ACC reduces the amount of attentional resources drivers must devote to driving, then drivers who use ACC may experience increased periods of mind wandering, which could reduce safety. Methods Participants drove a prescribed route on a public road twice, once using ACC and once driving manually. Mind wandering rates were assessed throughout the drive using auditory probes, which occurred at random intervals and required the participant to indicate whether or not they were mind wandering. Measures of physiological arousal and driving performance were also recorded. Results No evidence of increased mind wandering was found when drivers used ACC. In fact, female drivers reported reduced rates of mind wandering when driving with ACC relative to manual driving. Driving with ACC also tended to be associated with increased physiological arousal and improved driving behavior. Conclusion Use of ACC did not encourage increased mind wandering or negatively affect driving performance. In fact, the results indicate that ACC may have positive effects on driver safety among drivers who have limited experience with the technology. Application Driver characteristics, such as level of experience with in-vehicle technology and gender, should be considered when investigating driver engagement during ACC use. Field research on vehicle automation may provide valuable insights over and above studies conducted in driving simulators.

“…LDWS are assumed to improve drivers' situation diagnosis through their ability to capture a driver's attention (Ho et al, 2005;Spence and Ho, 2008). However, situation diagnosis also implies that drivers must make a cognitive assessment of the situation, taking into account various contextual elements, before acting (Kovordányi et al, 2005;Navarro et al, 2007). Thus, situation diagnosis requires some time to be completed and is dependent on both the context of the situation and the design of the warning signal delivered.…”

Influence of lane departure warnings onset and reliability on car drivers' behaviors

et al. 2017

Lane departures represent an important cause of road crashes. The objective of the present study was to assess the effects of an auditory Lane Departure Warning System (LDWS) for partial and full lane departures (onset manipulation) combined with missed warnings (reliability manipulation: 100% reliable, 83% reliable and 66% reliable) on drivers' performances and acceptance. Several studies indicate that LDWS improves drivers' performances during lane departure episodes. However, little is known about the effects of the warning onset and reliability of LDWS. Results of studies which looked at forward collision warning systems show that early warnings tend to improve drivers' performances and receive a better trust judgement from the drivers when compared to later warnings. These studies also suggest that reliable assistances are more effective and trusted than unreliable ones. In the present study, lane departures were brought about by means of a distraction task whilst drivers simulated driving in a fixed-base simulator with or without an auditory LDWS. Results revealed steering behaviors improvements with LDWS. More effective recovery maneuvers were found with partial lane departure warnings than with full lane departure warnings and assistance unreliability did not impair significantly drivers' behaviors. Regarding missed lane departure episodes, drivers were found to react later and spend more time out of the driving lane when compared to properly warned lane departures, as if driving without assistance. Subjectively, LDWS did not reduce mental workload and partial lane departure warnings were judged more trustworthy than full lane departure ones. Data suggests the use of partial lane departure warnings when designing LDWS and that even unreliable LDWS may draw benefits compared to no assistance.

“…The driver may turn-off the system at periods, or may ignore the system's warnings when other priorities rule (e.g., getting to a meeting in time). Even more importantly, drivers may (partly unconsciously) adapt their driving style by driving faster and paying less attention to the traffic when supported by ADAS [2]. This phenomenon has been commonly termed negative behavioral adaptation in the empirical research literature [3]- [7].…”

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

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