A Diploma Thesis titled “Identification of critical driving parameters affecting speeding using data from smartphones” was recently presented by Aris Kokkinakis. Data collected from sixty- eight drivers who participated at a naturalistic driving experiment for fifteen months were analyzed with the use of linear regression modelling. The results revealed that key parameters like distance, high intensity harsh accelerations and braking, harsh cornering, average deceleration and mobile usage, had statistically significant on driver speeding behaviour. The number of high intensity harsh brakings had the most significant impact on speeding, whereas for each type of road separately, distance was the most significant parameter.
