“…The use of gas generators (inflators) as a cost-and weight-efficient method to generate overpressure can be found in the literature for other applications than side crash protection with important benefits for crash performance [14]. In the present research, gas generators are also used for creating movement in the seat base and in the door.…”

-This research presents six simultaneous innovative occupant near side lateral impact protection concepts including a dynamic door, high-volume side airbag, a large external airbag that covers doors, sill and B-pillar of the struck vehicle and other concepts for increasing the distance between the occupant and the door panel (active armrest, inflatable door beam and moving seat). All systems are based on pre crash detection of the impact and are activated as soon as 80ms before the impact. This paper details the task of integrating these systems into a vehicle using FE models, sled tests, and full scale crash tests. Sled test dummy responses were compared with and without the countermeasures.

“…If future research shows that the risk due to A-pillar obstruction is indeed larger than hitherto believed due to the illusion of absence, car manufacturers may have reason to invest more resources into the development and implementation of car-design solutions that would reduce or eliminate A-pillar bind zones. Solutions that have been proposed include reducing the A-pillar width (Pipkorn et al, 2012 ; Vaidya et al, 2017 ) and using display solutions that allow the driver to virtually “see through” the A-pillar (Beresnev et al, 2018 ; Tragianis, 2014 ; Ylan, 2019 ). Blind spot monitoring systems (Forkenbrock et al, 2014 ) may also be worth considering.…”

“…Reducing A-pillar width would obviously reduce the risk associated with A-pillar blind spots. The consideration that the A-pillar also needs to be strong in order to protect the driver and passengers in case of roll-over, however, argues in favour of wider A-pillars (Bhise, 2016 ; Pipkorn et al, 2012 ). Thus, when making decisions about optimal A-pillar width, there is an inherent trade-off between competing safety concerns to consider.…”

“…Lastly, when evaluating the potential merits of different conceivable countermeasures aiming at reducing the risk of accidents associated with A-pillar obstruction, interventions based on improvements in A-pillar (Pipkorn et al, 2012 ; Quigley et al, 2001 ; Vaidya et al, 2017 ) or road design (Bez, 2018 ) would appear more promising than attempts at influencing driver awareness or behaviour (Marshall et al, 2012 ) if the illusion of absence plays a central role. The argument for this is that if the illusion of absence is indeed a visual and cognitively impenetrable illusion it may be very difficult or even impossible for people to acquire strategies and behaviours that would reliably make them immune to its deceptive powers.…”

The purpose of the present note is to draw attention to the potential role of a recently discovered visual illusion in creating traffic accidents. The illusion consists in a compelling and immediate experience that the space behind an occluding object in the foreground is empty. Although the illusion refers to a region of space, which is invisible due to occlusion (a blind spot), there is evidence to suggest that it is nevertheless driven by visual mechanisms and that it can be just as deceptive and powerful as ordinary visual illusions. We suggest that this novel illusion can make situations involving blind spots in a road user's field of view even more dangerous than one would expect based on the lack of visibility by itself. This could be because it erroneously makes the road user feel that (s)he has actually seen everything there is to see, and thus has verified that the blind spot is empty. This hypothesis requires further testing before definitive conclusions can be drawn, but we wish to make researchers and authorities involved in the analysis of traffic accidents and on-the-spot crash investigations aware of its potential role in order to encourage registration of relevant data and facilitate further research.
