abstract="Upgrade of the Ejisu-Kumasi section of the N6 saw the construction of roundabouts at selected intersections. Their use appears challenging particularly for vehicles with elevated Centre-of-Gravity. The objective of this study was to establish the relative risk of traffic accident deaths or hospitalized injuries at the roundabouts. Five-year crash data covering a 100 m stretch upstream and downstream of the roundabouts were analysed. A total of 119 crashes occurred with 18% casualty hospitalization and 12%fatalities. Compared with the Ejisu roundabout, fatal or hospitalized injuries were significantly higher at the Boadi (OR = 25.6, p = 0.0021) and Kwame Nkrumah University of Science and Technology Police Station Junctions (OR = 48.2, p < 0.001). Occupants of buses, heavy goods vehicles and riders of two wheelers were at elevated risk of deaths or serious injuries. Crash severity at the round abouts was aggravated by night-time, steep gradients and adverse cambers. It is recommended that, signalization and grade separation should be used in the current arrangement where appropriate.<p /> <p>Language: en</p>",
