Download in .pdf format Download in .docx format

Proposal to permit the manufacturer to specify its own formula for the calculation of scritical. The current formula does not take the dynamic behaviour of vehicles into account and therefore requires gaps that under some traffic conditions don’t usually occur. Since there are different ways of addressing the dynamic behaviour of the vehicles with regard to the original formula, this proposal would allow the manufacturer to specify its own formula provided the safety principle is maintained.
