Effect Analysis of Intelligent Speed Adaptation (ISA) in Advisory Mode on Community Roads

ISA is considered as an effective measure to reduce traffic accidents. To make the possibility analysis, an experiment is conducted by using a driving simulator. The outputs from the simulator are analyzed combined with the ages and road conditions. The experiment shows that the ISA can improve recognition to speed limitation and drivers’ behavior. Furthermore, drivers react significantly to voice assisted ISA; audible advisories by the ISA such as reduction of speed are acknowledged by drivers concluding positive effects on traffic safety.
