The excessive vehicular speeds coupled with the wide speed variations explain in part the high incidence of traffic crashes and fatalities on the Accra-Kumasi highway. An integrated speed monitoring and control program, and realigning the highway to by-pass small and medium settlements would be required as a long-term measure for the reduction of speed-related road traffic crashes, fatalities, and injuries in Ghana.
This program of research, which was guided by Haddon's Matrix and deterrence theory conceptual frameworks, essentially had five core objectives. These objectives were examined through five independent studies. The studies were broadly interwoven to clarify understanding in three broad thematic areas relating to the impact of alcohol use on road traffic crashes in Northern Ghana: (a) general behaviour (i.e., knowledge, attitudes and practices) regarding alcohol impairment as a risk factor for ii Alcohol Use and Traffic Crash Severity in Ghana road users, (b) police reported alcohol and illicit drug use and the relative risk of road traffic crashes, and (c) the impact of alcohol use on road traffic injury severity.Study 1 (Chapter 5) primarily aimed to determine knowledge, attitudes and practices regarding alcohol drinking and driving in three cities in Ghana. The study was a survey conducted at washing bays, lorry terminals and fuel stations. Study 1 established that 24% of all motorists and 54% of motorists who were current alcohol users reported having driven within an hour after consuming alcohol. Current alcohol users typically consume four standard drinks per drinking occasion. Further, participants who were current alcohol users were significantly more likely to be arrested for traffic violations compared with non-alcohol users. It was apparent that enforcement of drink-driving law and motorists' knowledge of the BAC law were low.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
