This paper examines evaluation of traffic crash fatality, causes and effects in Nigeria: A re-appraisal. Despite huge investments in new technology and transportation infrastructure, terrible accidents still remain a reality of traffic in Nigeria. With a total road network of 194,394km, Nigeria has the largest road network in sub-Saharan African. The majority of these roads were built years ago when vehicular traffic was limited and alternate modes of transit, such as trains, were available. However, the rise in automobile traffic has not been matched by an increase in road development at a comparable rate. It is therefore, a priority for Nigeria to have an appropriate accident information system and that they carryout appraisals and re-appraisals from time to time as well as evaluation studies of intervention measures.
