Abstarct: The aim of the current research is to provide a model of the influence of the interference zone of the ramp and the considered highway that this interference affects the traffic parameters including speed, flow, density and shock wave resulting from this flow interference. The presentation of the model in this research has been done using AnsysFluent finite element software. To achieve these goals, first the studied variables related to interference movements such as the speed of vehicles entering from the ramp to the highway, the speed of vehicles in the vicinity of the ramp, the amount of density of vehicles created on the highway and the considered ramp, the amount of shock wave under the influence of interference movements in the vicinity The ramp and the adjacent lane were examined. The results of checking the speed of vehicles show that the speed in the lane next to the entrance ramp is 25 km/h, and the speed in lane one of the entrance ramp is 26 km/h. The results of the traffic density survey in the studied axis show that the density value of the lane adjacent to the ramp is equal to 60.2 vehicles per kilometer, the density of vehicles in the first lane of the ramp reaches 2.56 vehicles per kilometer. The results obtained from the shock wave created in the studied axis show that its value in the lane adjacent to the ramp is equal to 23.30 km/h and in the lane of a ramp is equal to 0.33 km/h. Analyzing the output of Ansys software shows that due to the occurrence of interference movement in the studied axis, speed and density have an inverse relationship with each other, and also in displaying the shock wave and how the shock wave is propagated on the highway by the interference movement of vehicles at the points where There is interference movement in the flow, the shock wave reaches its maximum value.
