  ;, and the method further includes:
training the safety evaluation model by using the constraint function as the target, and solving, under a constraint condition, safety influence coefficients in the region safety quantification sub-model corresponding to the sub-region and the road safety quantification sub-models, to obtain significance of the safety influence coefficients at a 95% confidence interval, wherein when the safety influence coefficient is positively significant at the 95% confidence interval, traffic data corresponding to the safety influence coefficients increases incidence of traffic accidents on the traffic road; and when the safety influence coefficient is negatively significant at the 95% confidence interval, the traffic data corresponding to the safety influence coefficient reduces the incidence of traffic accidents on the traffic road.
