Abstract

Background: Road traffic crash threaten human health due to  crash injury mainly occurred by drivers fault.

Objective:  Estimating Exposure-Controlled Crash Risk at Roundabout among drivers in Addis Ababa City Administration.

Method: A case control study was conducted for driver of two vehicle crash paired by collusion. A total of 162 cases and 162 controls were randomly selected. Crash data were collected from November 2018 to March 2019. A statistical analysis of quasi-induced exposure and conditional logistic regression were conducted using STATA 14 software. Ethical clearance was obtained from Addis Ababa University, College of Health Science ethical review board.

Result: The vast majority of drivers were males (95.3% of the cases and 93.8 of the controls). The mean age of cases and controls was 34.3 + 9.0 and 34.6 + 10.7 years respectively. The study indicated that 37% cases and 30.9% controls have made fault of drive following too close driving, where as 30.3 % cases and 20.4 controls have made a fault of blocking the overtaking vehicle path.

Under 5-year vehicle age cause crash at a rate of 2.8: 1. Taxi drivers (OR=2.5 95% CI=1.0- 5.9) were at higher risk of crash responsibility compared to Automobile driver.

Conclusion: the majority of road traffic crash risk at roundabout were males, younger vehicle, taxi deriving and the driving fault like blocking the other overtaking vehicle path. Therefore, increasing number of lane & skilling up the driver to proceed cautiously at roundabout were recommended.
