Abstract
Road safety is an issue of vital concern to road authorities. Detecting accidents risk factors can contribute to make a road more efficient, safe and comfortable. The research is focused on safety problems related to road surface conditions, traffic facilities, and road users' behavior. Eight major national highways were selected to serve as the case study and assumed to represent highway networks in Sudan. A field survey of the current safety conditions was conducted on the selected highways. For each highway, the previous occurred accidents, road surface problems, and inadequate traffic control facilitieswhich directly related to road safety were visually surveyed. To achieve the research objective, a new rating system called "Risk Factor Index" (RFI) was established and adopted to measure the safety hazards condition on the selected highways. The results showed that all the surveyed highways scored "Medium" level of RFI except one road scored "low" level of RFI. It was found that the major risk factors of the highest RFI are improper road width, absence of median and deficiency in road lighting and marking. Based on the study findings, recommendations of necessary corrective measures were provided to enhance road safety.
