This paper describes two examples of human factors analyses on driver support systems: (i) a quantitative analysis on time-to-collision (TTC) using naturalistic driving data, (ii) a field operational test of the distance control assist system. The first analysis is to understand usual driving behavior in the real traffic condition and utilize the fundamental knowledge for concept making and design of driver support systems. The other is to identify changes in driving behaviors or driver's workloads using the system and clarify the system effectiveness. These kinds of human factors analyses are essential to the development of driver support systems.
