Agv traffic management system

A computer-implemented method performed by a computing system of an autonomous vehicle operating within a workspace, comprising:

• receiving first instructions identifying a path to move within the workspace;
• during execution of the first instructions, receiving a first signal from a transmitter device of the workspace, the first signal having a first transmission range of a first distance from the transmitter device;
• executing a first operation at the autonomous vehicle to reduce a speed of the autonomous vehicle based at least in part on receiving the first signal;
• while operating at a reduced speed, receiving a second signal from the transmitter device of the workspace, the second signal having a second transmission range of a second distance from the transmitter device, the first distance being greater than the second distance;
• and
• executing a second operation at the autonomous vehicle to halt motion based at least in part on receiving the second signal.

An inventory management system, comprising:

• a plurality of autonomous vehicles configured to move within a workspace according to generated paths, an autonomous vehicle of the plurality of autonomous vehicles comprising:
• a receiver configured to receive a first signal of a first frequency and a second signal of a second frequency;
• and
• a transmitter configured to communicate with a management computer system,
• the management computer system configured to:
• receive a first indication from a particular autonomous vehicle of the plurality of autonomous vehicles, the first indication indicating reception of the first signal by the receiver;
• based at least in part on receiving the first indication, instruct the particular autonomous vehicle to reduce a travelling speed;
• receive a second indication from the particular autonomous vehicle, the second indication indicating reception of the second signal by the receiver;
• and
• based at least in part on receiving the second indication, instruct the particular autonomous vehicle to stop moving within the workspace.
