A Diploma Thesis titled ‘Investigation of the impact of mobile phone use to driver behaviour and safety with the use of driving simulator’ was presented by Leonidas Roumpas in February 2010. Lognormal regression and binary logistic methods were used to investigate the influence of mobile phone use as well as various other parameters on the mean speed and the probability of an accident. From the models application it appears that mobile phone use leads to a statistically significant decrease of the mean speed in urban and interurban environment and to an increase of accident’s probability, probably due to distraction of driver attention and as a result, delayed reaction time at the moment of the incident. It appeared that in rainy conditions drivers did not present different driving behaviour, however, they had a high probability of being involved in an accident.
