Most importantly, the safety and comfort benefits of each driver support system need to be thoroughly evaluated as to minimise unsafe behaviour in the form of behavioural adaptation, driver distraction or high workload.
In collaboration with the United States Agency for International Development (USAID) and Family Health International, the Ministry of Health of Jordan has implemented a workplace-based unsafe sexual behavioural prevention programme in QIZs and small businesses.
Unsafe system behaviour stems from the behavioural safety constraints not being met (Leveson 2012).
'Unsafe acts' are a behavioural aspect of safety widely considered to have a significant impact on the frequency and severity of accidents in many industries, an idea stemming from the earliest days of safety science (e.g. Heinrich 1959).
Biomechanics looked at vehicle features that contributed to more and more severe injuries, civil engineers looked more closely at road environment features, and behavioural scientists looked at unsafe road behaviours contributing to crashes and injuries.
It seems that this study was successful in countering a trend towards unsafe sex within steady relationships, a difficult behavioural goal to achieve in HIV prevention.
These risks are varied - from the structural violence of poverty, environmental degradation, lack of access to health care services and unsafe working conditions - to seemingly modifiable behavioural risk factors such as tobacco use.
Food safety behaviours are often subdivided into specific behavioural constructs such as personal hygiene, adequate cooking of foods, avoiding cross-contamination, keeping foods at safe temperatures, and avoiding food from unsafe sources [ 78].
While the less educated and the poor most likely travelled more often by foot, they might also have been exposed to undetermined environmental (neighbourhoods with unsafe roads), biological (poor vision or decreased mobility due to poor health) and behavioural (alcohol or other substance use) risk factors for pedestrian death.
In their paper about behaviourally relevant road categorisation, Weller et al. [6] argue that "unsafe situations are likely to occur if the perceived message conveyed by cues or affordances does not match the normative behavioural expectations of the official road category.
