The present Diploma Thesis aims at the investigation of the impact of road lighting in urban and rural roads on the frequency and severity of accidents. For the achievement of this objective, appropriately processed data were used from the database of the Department of Transportation Planning and Engineering of the National Technical University of Athens (NTUA) and lognormal regression models were developed. The application of these models led to the investigation of the influence of road lighting and other parameters such as weather conditions, accident type, vehicle type etc. on the number of casualties and injuries. It appears that road lighting contributes to the reduction of the number of accidents and their severity and that this influence increases with the increase of the severity of the accidents.
