Kallia Aggeloussi, Angeliki Kanellopoulou, “Identification of road accident human cost and driver sensitivity towards accident risk. Use of methods willingness-to-pay and stated preference”, NTUA, School of Civil Engineering, Athens, March 2002.

The objective of this diploma thesis is the identification of road accident human cost in Greece on one hand and the Greek drivers’ sensitivity towards road accident risk on the other. The definition of the double target is followed by bibliography research, the adoption of the methodologies, the execution of a questionnaire-based field survey on a representative sample of Greek drivers and the related statistical analysis. The human cost is estimated using the willingness-to-pay approach, which is applied in Greece for the first time and the amount the society values a road accident fatality in Greece, was estimated at 668.500 euros. The drivers’ sensitivity towards accident risk is analyzed using the stated preference method, in order to identify drivers’ behavior through the development of a logistic regression model. The result was that most of the drivers wish a risk reduction and that the choice among small and large reduction depends on the gender, the family situation, the driving experience, the annual family income, the cost of a journey and notably the trip duration increase.
