Limitations of an Integral Safety Concept in Longitudinal Traffic to Meet Vision Zero 2013-01-0728

In order to meet the growing requirements on vehicle safety, additional safety systems are usually integrated that then fulfill a certain function. The function only becomes active in the defined use cases, since it could have a negative effect on the vehicle safety in other situations, or the necessity of intervention is not at all recognized. For the implementation of a traffic system without traffic fatalities, it is very difficult to implement this method, since an infinitely large number of situations have to be taken into consideration. In an integral safety concept, the individual safety systems are closely networked and act interdependently with each other. This paper will examine in simple scenarios whether it is possible to ensure accident-free driving such that the so-called Vision Zero can be realized in any case.
