The invention relates to the technical field of intelligent traffic, in particular to a ramp road section passing energy efficiency detection method and system. The method comprises the following steps: acquiring image data of a ramp road section, and constructing a virtual road model of the ramp road section; acquiring image data and vehicle position detection data of passing vehicles on ramp road sections, inputting the image data and the vehicle position detection data into the pre-training model, and matching three-dimensional models corresponding to the passing vehicles; and mapping the matched three-dimensional model into the virtual road model of the ramp road section according to vehicle position detection data to display the vehicle passing condition in a three-dimensional visualization manner. According to the invention, the virtual three-dimensional model of the vehicle is mapped to the created virtual road model, three-dimensional visualization real-time display is carried out on the passing vehicle, and the lane changing and line pressing condition of the passing vehicle is judged according to the intersection of the moving track of the passing vehicle and the traffic marking characteristics in the virtual road model and early warning is carried out. Therefore, the three-dimensional visual management and control of the ramp road section can be realized, and the traffic condition of the ramp road section can be mastered in real time instead of traditional snapshot.
