Abstract

Driving behavior such as speed reduction is needed for risk aversion while driving although the behavior leads to a decrease in travel utility. In this paper, a driving behavior model applying subjective risk and driving utility is proposed as a fundamental study for 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 changes in the traffic environment is proved. Lastly, applicability of the model is confirmed with 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.
