Q

Examples of the effect of heat stress on driving:

A
  • Decreased perception and attention impair driver action
  • Missing and overhearing signals
  • Decreased attention to secondary tasks, e.g. observing speed, emergency vehicle horns, flashing light signals
  • Increase in reaction time (by approx. 22% when the interior temperature rises from 21°C to 27°C) [TAX99]
  • Decreasing visual performance (Visual acuity decreases linearly with the increase in body temperature)
  • Agressive driving behaviour (e.g. determined by drivers’ honking behaviour).

Q

Properties of CSG (Composite Safety Glass)

A

+ Cohesive after breakage (stone impact)
+ Improved break-in safety
+ Less danger of ejection in case of an accident
+ Sound damping
+ Ushering in a new dimension of functions (sensor technology)

  • Costs
  • Weight
  • Cohesivness

CSG - mainly in windscreens
SSG - mainly side and rear windows
