Statistical Overview of Factors Influencing Traffic Accidents Severity On El-Brega Coastal Freeway in Libya

Background:Globally, Road Traffic Accidents (RTAs) are one of the significant causes of fatality and injury. In Libya, RTAs have resulted in disabilities andwere the third leading cause of death. However, there is a lack of information on RTAs and road safety in Libya. Objective:The present study aims to fill the knowledge gap by performing a statistical analysis to identify the factors associated with road accident severity inEl-Brega Coastal Freeway. Methods:RTAs data extracted from police investigation reports in Ajdabiya Municipality for the period from 2001 to 2010. Then descriptive analysis andBinary logistic regression model (BLM) are applied to analyzing the data. Results:Descriptive analysis results showed that between 2001 and 2010, approximately 45% of RTAs in Ajdabiya Municipality occurred on El-BregaCoastal Freeway, and more than 1225 individuals lost their lives or sustained injuries in these RTAs. Furthermore, Sixty-two percent (n = 137) ofthose who died in accidents were from the 20-45 age group. BLM Results concluded that only eight predictors have statistical significant withaccident injury severity. Five of them increase the likelihood of injury severity. A head-on collision is the prime influence factor to increase injuryseverity odds, followed by high-speed driving, Weekends, horizontal curves, and driver’s age. While accident injury tends to be less severe withthe other predictors like rollover collision, rear-end collision, and accidents involving animals.Conclusion:Thus, implementing the use of seat-belt and speed control regulations, with activating ambulance services are the urgent countermeasures toenhance road safety.
