abstract="This study focuses on the development of a driving risk model based on speed deviation. Speed data were collected via an on-site driving experiment on the Sanyo Expressway in Hiroshima Prefecture in Japan in 2009 to examine the impact of in-vehicle traffic warning information (IVTWI) on traffic safety. To compare the impact of IVTWI provision on traffic safety, we examined three driving scenarios, (i) without IVTWI, (ii) voice-based IVTWI, and (iii) voice and image-based IVTWI. Driving risk was defined by three levels (low, medium, and high) based on the magnitude speed deviation using an ordered response probit model. <br><br>RESULTS show that traffic safety could be improved by IVTWI provision. A high driving risk, as derived from the proposed method, could explain the occurrence of up to 38% of traffic accidents. The results of the constructed model confirm that the probability of driving risk could be reduced by IVTWI provision.<p /> <p>Language: en</p>",
