Abstract

This study examines the daily Road Traffic Crashes (RTC) casualties in Osun state of Nigeria, Comparison of two quality control schemes identified as exponential Weighted Moving Average (EWMA) and Poisson Cumulative sum (CUSUM) control chart techniques were made using data collected from Federal Road Safety Corps (FRSC) Osun-State over a period 120 months our findings revealed that both techniques are capable of detecting small shift from mean level but Cusum is more sensitive. Furthermore, the points of change in the process are clearly identified and easily located on both schemes. The findings provide a proper diagnostic solution in the area of Road Traffic crash (RTC) reduction and control in Osun state Nigeria.
