Autonomous vehicle maneuver in response to construction zone hand signals

A system comprising:

• an autonomous vehicle configured to travel along a road, wherein the autonomous vehicle comprises at least one sensor;
• a control device associated with the autonomous vehicle and comprising a first processor configured to:
• access sensor data captured by the at least one sensor, wherein the sensor data provides information about at least a portion of an area in front of the autonomous vehicle;
• detect, from the sensor data, a construction zone;
• detect, from the sensor data, that a construction worker is altering a traffic flow using a construction zone-related hand signal, wherein the construction worker is on a traffic lane adjacent to the construction zone and facing oncoming traffic;
• determine an interpretation of the construction zone-related hand signal;
• determine a proposed trajectory for the autonomous vehicle according to the interpretation of the construction zone-related hand signal;
• and
• transmit at least one of the proposed trajectory and the sensor data to an oversight server;
• the oversight server operably coupled with the control device, and comprising a second processor configured to:
• receive the at least one of the proposed trajectory and the sensor data;
• determine whether the construction zone-related hand signal is in use to alter the traffic flow;
• in response to determining that the construction zone-related hand signal is in use to alter the traffic flow, determine whether the proposed trajectory causes the autonomous vehicle to go outside of an operational design domain that indicates pre-mapped geographical areas where the autonomous vehicle is able to autonomously travel;
• and
• in response to determining that the proposed trajectory does not cause the autonomous vehicle to go outside of the operational design domain, transmit, to the control device, an instruction that indicates to perform the proposed trajectory.
