Abstract
A miniature autonomous vehicle for operation on the public roads is disclosed. The small size allows efficiency for small payloads, but produces a danger of being overlooked by other vehicles. The size of the vehicle is less than driver operated vehicles and may be restricted to less than 200 pounds. Sensors determine the vehicles speed and the presence of environmental vehicles and use a processor to calculate the need for additional visibility. A visibility structure and support structure with lights or markers is controlled by the processor. The markers are controlled in their operation or position by the processor on the basis of the sensor data. Extending or raising and retracting or lowering the structure affects the air resistance and stability of the vehicle. The structure can be raised when the vehicle stops or is in traffic and lowered at road speeds in light or absent traffic.
