The high rate of urbanization experienced in developing countries pose a great challenge to transport development in most cities. The study examined traffic congestion problems and their causes at road intersections in Bamenda, Cameroon. Secondary data was obtained from both published and unpublished materials, libraries and internet sources and primary data from field photographs, administration of questionnaires to a sampled population of 220 respondents. The data was analyzed by the use of quantitative and qualitative methods including SPSS and the output presented in the form of graphs, charts and tables. The analysis of data collected revealed that spatio-temporal variations exist in traffic flows and delays at specific intersections. Also poor town planning, poor driving habits, absence of traffic control mechanisms, lack of parking space, road side trading and hawking, were found to be the greatest causes of delays at the road intersections in the city. Based on this, the study therefore recommends that, trading activities and poorly parked vehicles and attitudes of road users be strictly prohibited especially at road intersections to reduce traffic congestion and delays within the city.
