Traffic incident detection,as an important item of all-factor perception on smart highways,has been widely used in recent years.Since the placement of traffic incident detection facilities on smart highways is denser than that on traditional highways,their placement needs to consider the impact that the highway's alignment and profile,traffic signs along the highway and overpass bridges have on the monitoring range of inspection cameras.This paper adopted the method of 3D modeling to establish a federated model that reflects the highway's design,the layout of various kinds of facilities along it,and the camera's effective monitoring range model in 3D space.Then the placement of video traffic incident detectors on highways in 3D scenes was discussed.The guidance for designing the layout of video traffic incident detectors on highways is given.
