Abstract

<p> The use of ICT in snow plowing and removal operations is being promoted in snowy and cold regions due to an aging workforce and labor shortages. However, the digitalization of the snow removal patrols, which are used to determine the timing of snow removal, is still in preliminary stages. The vehicle-mounted mobile mapping system (MMS), which transforms the snow conditions of roads and shoulders into 3D point clouds, is useful in advancing the digitalization of snow removal patrols. This study develops an MMS integrated with a low-cost GNSS/INS to investigate the possibility of adopting an affordable MMS for snow removal patrols. The accuracy of map coordinates in MMS-generated point clouds in the post-boresight calibration has beenwas evaluated using control points in urban blocks. The map coordinate accuracy has been evaluated to be 0.085 m (3D) and 0.032 m (2D). Based on this result and the availability of inexpensive commercial LiDARs, an inexpensive MMS can be developed for measuring snow cover on roads and shoulders.</p>
