In addition,
the backward strategy was used to remove some insignificant
items and modify the prediction model. Finally, the improved
model can be applied to predict the traffic fatalities and its
confidence interval. The results show that the recent road traffic
deaths in China have significant linear relationship with GDP,
the number of traffic fines and the number of serious traffic
accidents, and the proposed model can provide an accurate
traffic deaths prediction. In general, this paper contributes to
prediction of the road traffic fatalities, which provides the traffic
management administration guidance for policy development
and resource allocation regarding road safety in China.
