Abstract

The huge number of accidents makes the study of accidents causation one of the priorities in the design of roads, location of traffic signs, specifying the permitted ages for driving, improving license procedure and to provide local data to predicate the behavior. The characteristics of drivers affect results in roads. Drivers' data, vision test and reaction time of the drivers taken, head cover and spectacle considered in the drivers' abilities and accidents background involvements in the questionnaire form. Drivers' reaction time and drivers' accidents rate (accidents+1/experience) through the years of driving experience are modeled. The results revealed the negative impact of head cover and/or spectacle on vision abilities, while it didn’t show obvious effect on accidents rate The best reaction time is 0.5708 (sec) for age group (29-39) years, while the worst reaction time is 0.6974 for age (>=51) years. The maximum accident rate is 0.482 for age group (18-28) and decreases with age increase to a minimum accidents rate of 0.0808 for age group >=51.
