An NTUA Diploma Thesis titled “Critical driving parameters affecting speeding using data from smartphones” was recently presented by Dimosthenis-Marios Tzoutzoulis.  The aim of this Diploma Thesis is to identify the critical driving parameters affecting speeding using data from smartphones.  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. pdf5 ppt5
