Evaluation Of Intelligent Vehicle Safety Systems - A State-Of-The-Art Example

This paper describes an example used to evaluate an intelligent vehicle safety system (IVSS). The EU funded project eIMPACT included the evaluation of traffic effects of IVSS. Evaluations can support or counter-weigh the safety benefits of such systems and provide economic feedback as well. For deeper insight into the safety effects, the traffic simulations carried out also indicated so-called surrogate safety measures, which can be used to supplement the dedicated safety evaluations. The author presents both the traffic effects of selected IVSS and the safety parameters as they result from micro simulations. In almost all cases the indirect traffic effects from avoided accidents outweighed the direct effects by far. The author concludes that neglecting such benefits would draw a too pessimistic assessment of the IVSS.
