Driver reliability and behavior study based on a car simulator station tests in ACC system scenarios

Research on human safety is a complex, time consuming, and extremely important process. Especially in the car industry which is a huge market. Such research contains both crashworthiness of a vehicle structure, biomechanical study and research on driver behavior and his/her reactions. It may be tested either by means of computer simulations or real crash experiments. Simulations are time consuming but provide recurrent test. Unfortunately, they need a validation in a form of an experiment [33], which could be expensive. Moreover, sometimes it is impossible to make a recurrent experiment and there is a considerable risk of failure, i.e. in crash tests it may reach 13% [27]. In research on a driver behavior and reaction, both questionnaire studies and simulators can be distinguished. Questionnaire research covers many issues and often relates to the simulator one, i.e.: user knowledge about ADAS [29], in-depth exploration of perceptions towards automated vehicles [4], evaluation of the HMI intuitiveness [8]. Simulator research is being used from 60’s of XX century, when development of car simulators in UCLA [32], GM Styling Staff [3], Table 3. Steady state availability versus for Case 2
