The multipurpose road laboratory for spatial data collection conducted the first field trips
The mobile measuring system was developed by order of the Russian road research Institute. The requirements for the technical equipment of the mobile laboratory were formed based on the results of comparative tests in 2019. A specialized machine has got all necessary to create a digital model of highways with high accuracy. The model will be uploaded to the road Fund control system (a single digital database of all roads in the country).
The work is carried out within the framework of the Federal project “system-wide measures for road development” of the national project “Safe and High-quality roads”. The road laboratory includes a mobile laser system, a GPR system for subsurface sensing, video cameras, equipment for surface diagnostics, and a set of geodetic equipment.
The universal road laboratory is currently used to build a digital model of Federal public roads. According to the survey results, almost 2 terabytes of field data have already been obtained. These are the results of mobile laser scanning, the results of georadar survey (“transparent” layers of road construction), data for assessing the technical condition of the road (measured longitudinal evenness and surface defects are detected).
Then cameral processing is carried out. It includes calculating the exact trajectory of the road laboratory. The trajectory is necessary for forming a point cloud of laser scanning results (visually it looks like a digital double of the road, infrastructure, construction elements, etc.), as well as adding GPR profiles (radarograms of the road surface and roadbed) to the model. Spatial data binding is performed using networks of reference (satellite) stations.
“Sections of the R-298 Kursk-Voronezh highway-the R-22 Kaspiy highway with a length of 150 kilometers and the R-193 Voronezh – Tambov highway with a length of 200 kilometers have already been surveyed. Point clouds were formed along the 56-kilometer segment of the first section. Structural lines have already been drowned,” says ROSDORNII.
A contractor is also being selected to supply two more road laboratories to create a digital road model. It is planned that the machines will start working by the beginning of next year. In 2021, as well as in 2022, work will continue on Federal highways, and the regional network is expected to start “digitizing” in 2023.
