Abstract
This paper introduces the regression control chart for monitoring the road accident fatalities considering the effect of the external covariate, the number of road accident crashes. The recorded occurrence of road accident fatalities and crashes in a state in the western part of Nigeria was monitored using the conventional individual control chart and regression control chart which integrates two robust methods as the basis of analysis: the linear regression model and the Shewhart control chart theory. The designed conventional individual control chart detects month when road accident fatalities is out-of-control while the regression control chart could not detect any out-of-control. It is therefore recommended that regression control chart be used when the effect of external covariate(s) are being considered.
