| Outline of Final Research Achievements |
We developed a method to grasp rat-run traffic situation based on vehicle probe data. Then, we conducted a field experiment to analyze the impact of the an incentive program on drivers' rat-run route choice behavior. The results show that, on average, the percentage of rat-run route use was reduced by about 40% and that the effect by the reward concept was greater than that by the penalty concept. And more, we estimate the amount of reduction in the number of accidents and the amount of expected insurance payments by insurance companies due to the introduction of a telematics insurance for reducing rat-run traffic. The results showed that the maximum reduction of accidnets is 77% and the average reduction is 52% by subjects.

| Academic Significance and Societal Importance of the Research Achievements |
本研究におけるフィールド実験および事故減少量，保険会社の期待支払保険金額の減少量の試算の結果，保険会社の期待支払い保険金額の減少は実験で用いたインセンティブ額と比較すると低くなっているものの，当該実験対象区間という限られた経路での事故減少による試算であることや，サポート人件費といった考慮できていない要素もあり，対象範囲の拡大により逆転する可能性があることが示唆された．本成果は，抜け道抑制型テレマティクス保険の実用化に向けた検討に資するものと考えられる．
