Driving behavior such as speed reduction is needed for risk aversion when driving although it leads to decrease in travel utility. In this paper, a driving behavior model applying "Subjective Risk" and "Driving Utility" is proposed as a fundamental study for the evaluation of traffic safety measures considering the trade-off between safety and travel utility. Then, the mechanism of changing "Driving Behavior", "Subjective Net-Utility", and "Social Net-Benefits" due to the change in traffic environment is proved. Finally, the applicability of this model is confirmed with observed data at non-signal intersections. It is found that this model can be applied in comparing the level of "Subjective Risk" and the assumption is verified.
