Why response time must be reduced
For rescue operations ‘response time’ is one of the measures for effectiveness. In emergency situations response time should be as short as possible as this could be crucial for saving lives or properties at danger. Accordingly, much effort is put into reducing response times. But actually, what is response time?
Some products are so functional and effective that there is little potential to improve them. The violin, for example, was designed by the Italian master violin-makers in the 17th century. Countless efforts have been made to challenge its basic construction in order to improve it, but in vain. The violin is so close to perfect that no one has come up with a fundamental improvement during the last 350 years.
Black ice on the road is rightly considered very dangerous when driving. Still, many drivers are not watchful enough in weather conditions where there is the risk of black ice. But, what is this black ice – and what should I know about it?
Typically, black ice is invisible. It’s a thin coating of glaze ice on the road surface. Since it’s thin and transparent, the black road surface is clearly seen through it, and that is why it’s called blackice.
The typically low levels of noticeable ice pellets, snow, or sleet surrounding black ice means that areas of the ice are often practically invisible to drivers. Accordingly, the driver is not prepared of the slippery road area, and there is a risk of unexpected loss of traction. This in turn may result in subsequent accident.
Black ice sometimes forms from super-cooled rain which freezes into ice and constitutes a particular risk to winter traffic because it is extremely slippery and hard to spot. The temperature may be above freezing but the road surface may still be slippery.
The road surface can be well below freezing temperature – while the vehicle thermometer suggests it is not freezing.

Response time is a sum of parts
The total response time could be split into three clearly different phases:
It’s quite obvious that the potential for reducing response time will differ considerably depending on what phase we’re looking at.
