• Driving behavior such as speed reduction is needed for risk aversion while driving although the behavior leads to the 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 the changes in "Driving Behavior", "Subjective Net-Utility", and "Social Net-Benefits" due to the changes in traffic environment is proved. Finally, the applicability of the model is confirmed with the data observed at non-signal intersections. It is found that the model can be applied to comparing the level of "Subjective Risk" and that the assumption is verified.
