The safety potential of dynamic Intelligent Speed Adaptation (ISA) has been evaluated greater than for fixed options. Before dynamic ISA is ready for the market, problems have to be solved regarding for example reliable detecting of adverse weather conditions. There are also problems to be solved in choosing relevant maximum speed settings for and selecting the safest ISA HMI for adverse weather conditions like ice or snow on the road. Some indications on the problems and solutions regarding dynamic ISA can be received from studies that are carried out on Finnish road network, in a UK driving simulator and by driving tests with an instrumented car of VTT in Finland. These studies are presented together with preliminary conclusions drawn from the results. For the covering abstract see ITRD E123876.
