Continuous Flow Intersection (CFI) traffic design mode is one of the Unconventional Intersection Design (UID) modes studied by many researchers. While, most existing researches are specific design cases evaluation or comparison analysis based on traffic simulation software. The lack of systematic and theoretical modeling research for this design mode limits its application in practice. This paper studies the characteristics of the traffic flow’s moving in CFI mode, building the delay and queue model of each traffic flow based on shock wave theory, and put forwards the optimal coordinated timing model and solving methods. The case study shows that the optimal timing model proposed by the paper can run efficiently and produce very good timing schemes; and can provide good theoretical support for the application of CFI traffic design mode.
