STUDY ON BEHAVIORAL ANALYSIS OF DRIVERS: A SURVEY WITH QUESTIONNAIRES

The road transport system is based on driving characteristics: a large amount of accidents is related to more or less serious violations of rules of the Highway Code. It is obvious that different drivers have different behaviors in the same situations, less obvious is to know what percentage of a given population has some similar behaviors (e. g. due to factors such as driving experience, age and/or sex) and how this knowledge can help in the road studies. To learn the driver's behavior, it can be useful to measure road speed (V85 or operating speed) in some default road situations (geometrical or environmental). Often the recorded data, when numerically significant, tend to a normal distribution. In some cases it is possible to define different data distributions where to was appreciated the contribution of two very different driver's behaviors. In order to better characterize the different driver's behavior a survey with questionnaires is started. The survey modules are composed with multiple sections. The starting section containing personal data is investigated with Dula Dangerous Driving Index (DDDI), Driver Behaviour Questionnaire (DBQ), Traffic Locus of Control Questionnaire (T-LOC), Marlowe Crowne Social Desirability Scale (MCSD), Car Selection (CS), Car Characteristics Selection (CCS). The questionnaire is filled by 300 persons, and the answers are checked and analyzed. For example with the DDDI, different driving styles are identified, with the DBQ some types of recurring errors. At the end it is possible to analyze the responses also in terms of age and sex and these have highlighted attitudes such as the driving anger, the risk perception, the potentially risky behavior, the anxiety, the perception of control, the respect for the rules. The results obtained indicate that the survey must be continued to improve the driver’s characterization.
