Road accident death toll forecasting based on unbiased gray verhulst model

On the basis of analyzing the road accident figures of the past a few years, we predict the Road accident Death toll by introducing the unbiased gray verhulst model. By comparing and analyzing the forecasting results of unbiased gray verhulst model and Gray verhulst model, we find the former is more precise than the other. As it is shown, unbiased gray verhulst model forecasting results preferably show the road accident development trend and are feasible.
