A system for acquiring, processing, storing, analyzing and reporting data relating to the condition of a road or other pavement surface ( 102 ) in real time. The system includes a digital camera ( 104 ) mounted on a vehicle and positioned relative to a pavement surface ( 102 ) so as to capture images of the pavement surface ( 102 ) while the camera ( 104 ) is moving relative to

Feb 17, 2021 · The studies about road surface type classification using inertial sensors we were able to identify were conducted in two vehicle types: wheeled ground robots [23, 43, 49] and cars [48, 51, 52]. Since the structure between the two vehicle types is very different, and there is a vehicle dependency property, the papers using wheeled ground robots

Answer (1 of 2): It all depends on the type of pavement. i.e., if it’s flexible or not. Usually, concrete roads (not cement roads) are considered non-flexible. The load the tyre imparts to the non-flexible pavement is almost given back to the tyre itself wearing it down as opposed to a flexible p

The pavement dynamic response under vehicle moving load can further be used to obtain traffic information, including vehicle speed, vehicle type, and vehicle weight among other characteristics. The weight-in-motion (WIM) system is one of the most popular technologies for traffic monitoring, which can be divided into two types [11] .

Dec 30, 2019 · The vehicle is the focus of attention in this study, and the region of interest in the image is thus the highway road surface area. At the same time, according to the camera’s shooting angle, the road surface area is concentrated in a specific range of the image. With this feature, we could extract the highway road surface areas in the video.
