An NTUA Diploma Thesis titled “Correlation of declared and revealed driver behaviour using smartphone sensors” was recently presented by Nadia Kokkali. 19 drivers naturalistic driving data were collected through the OSeven smartphone application and the respective questionnaire. Two regression poisson statistical models were developed, indicating that driving experience, driver age, number of injury accidents in which the driver was involved, vehicle age, fines received by the driver during the last 3 years are all associated with increased harsh events. In most of the cases, a convergence between stated and revealed behaviour was observed.
