In order to improve road safety, automobile manufacturers have been developing several types of Advanced Driver Assistance Systems (ADAS) including collision warning, arouse attention and so on. This paper describes effects of collision warning and arousing attention on driver behaviour in different driving situations by using a high fidelity driving simulators. First it was investigated how car-following behaviour was influenced in response to different types of driver support systems. Next it was investigated effect of collision warning and arousing attention on car-following behaviour and its impact on driving safety when critical situations occur. The results showed that arousing attention may contribute to longer time headway during car-following depending on driving situations. Moreover there was a possibility that combining the use of collision warning and arousing attention may induce decreased collision risk compared to driving condition in which only collision warning is available. Potential implication of these results includes how to design driver support systems with arousing attention.
