摘要： A method includes the steps of detecting a trigger for speed scale setting for a vehicle autonomously operating at an underground worksite and executing a drive order, defining a speed scale for the vehicle on the basis of traffic flow of vehicles at the work site, transmitting a speed scale control message to the vehicle during execution of the drive order, the speed scale control message comprising a speed scale information element indicative of the speed scale, and transmitting, in response to detecting trigger for speed scale cancellation on the basis of updated traffic flow information, a speed scale cancel control message to the vehicle executing the drive order, wherein the speed scale cancel control message indicates cancellation of the speed scale.
