Abstract:
Urban areas significantly impact crash injury severity due to high traffic density and complex road patterns. This study analysed factors influencing fatal and non-fatal injuries in single-vehicle crashes on urban roads in Ghana from 2017 to 2020, using data from the Driver and Vehicle Licensing Authority (DVLA). The Random Parameter Logit Model revealed that younger drivers (under 20) are at higher risk for both fatal and non-fatal injuries. Crashes involving saloon cars, pickups, and minibuses had higher injury risks. Severe frontal damage increases the likelihood of both non-fatal and fatal injuries. Newer vehicles (under 5 years) showed lower injury risks. Crashes at controlled intersections and daytime crashes were less likely to result in fatal injuries. Failure to yield the right of way and mechanical failures were significant contributors to injury severity. The study highlights the need for targeted road safety interventions.
