Earthwork transportation refers to the large amount of earthwork generated by construction projects, which needs to be transported to other places for disposal. The disposal methods include using earthwork for off-site backfilling or transporting excess earthwork to other places for unloading. However, in the traditional earthwork site management process, the number of transportation vehicles in the earthwork site lacks scientific management, which easily leads to too many transportation vehicles in the earthwork site, resulting in too high vehicle density in the earthwork site, frequent congestion in the access channels, and affecting construction efficiency; Moreover, due to the heavy load and high center of gravity of earthwork transportation vehicles, driving on potholes will cause unstable driving of vehicles, increase the risk of traffic accidents such as rollover and collision; At the same time, when vehicles are transporting slag in the earthwork site, the slag is easy to adhere to the vehicle, and the vehicle will bring the slag to the road during driving, causing road pollution and dust pollution, affecting the city's environmental sanitation and air quality.
