An NTUA Diploma Thesis titled “Critical driving parameters affecting speeding using data from smartphones” was recently presented by Dimosthenis-Marios Tzoutzoulis.  Data were collected from the OSeven smartphone application of 200 drivers in naturalistic driving and four log-linear regression models were developed correlating speeding with driving characteristics and with answers to dedicated questionnaire. The results demonstrate that the number of harsh accelerations, the percentage of mobile use and the distance of the trip affect the speeding percentage and are correlated with the aggressive behavior of the drivers.  Furthermore, increased average acceleration does not always lead to breaking speed limits. Finally, male drivers tend to drive faster in comparison with women.
