Abstract
This study tries to appraise extreme weather events on road accidents over a period of 10 years (2004- 2013) and also examines the frequency of fatal, major and minor accidents in relation to weather conditions along the Lagos-I badan expressway. The data collected include the yearly occurrence of road traffic accidents along the Lagos Ibadan expressway (2004 2013), weather elements such as minimum and maximum Temperature, Rainfall amount, Wind speed, Relative Humidity and Sunshine hours. Data on road accidents (Reported cases, casualties and vehicles involved) were collected from the Federal Road Safety Commission, Moniya, Ibadan and Nigeria Police Force Headquarters Eleyele, Ibadan while weather variables were collected from Nigerian Meteorological Agency Oshodi, Lagos state. Both descriptive and inferential statistics were used for the analysis. Descriptive and inferential statistics including tables, charts, Trend analysis, Analysis of Variance, Regression and Correlation analysis were used to analyze the data. The results revealed that some climatic factors examined work together to cause road accidents. Hence, weather conditions have a pronounced impact on road accidents because fog, slippery roads, flood, erosion, visibility, smoke, dew, heat and radiation one way or the other affect the easy movement of vehicles thereby resulting in different forms of accident. The study recommends that Federal Road Safety Commission and other relevant agencies should organize workshops and seminars for the drivers on the etiquette of being safety conscious on the highways.
