In order to realize the safety evaluation of freeway alignment design in the design and construction stage and find out the potential traffic safety hazards, carry out a study on the expressway traffic accident prediction model. Based on the relevant alignment design, traffic characteristics and accidents data, build the primary accident prediction model, considered different conditions of alignment design and traffic control features of the influence of the traffic accident, adjusted the primary accident model by accident correction factor, established an active expressway accident prediction model based on alignment design and traffic characteristics, and carried out the goodness of fit test and example verification. The results show that the fitting effect of the model is good, and the accident prediction results are close to the actual accident data, which proves the validity of the model. The research results can provide theoretical basis for freeway improvement measures in the design and construction stage and improve the level of freeway traffic safety.
