Abstract(in English) | This study proposes a framework to detect hazardous spots on roads by combining mobile sensing on commercial-use vehicles with vehicle-to-vehicle (V2V) opportunistic networking. In the proposed system, a vehicle periodically makes a tentative decision regarding the state of the road using its own sensing data by a machine learning (ML)-based technique; however, the final decision is made by applying the Viterbi algorithm. In addition, our study introduced a V2V cooperative data processing technique to achieve higher accuracy in the detection of perilous spots. Numerical simulation analyses were conducted by using the dataset of "working car project" commissioned by NICT. It was shown that the Viterbi algorithm significantly improved the accuracy of detecting hazardous spots. It was also demonstrated that the proposed V2V cooperative framework had the potential to enhance the accuracy of detecting hazardous spots for all the vehicles in a community. |
