The disclosure is directed to a pathway article, such as an enhanced sign, that provides information about characteristics of the vehicle pathway to a computing device onboard a vehicle. An enhanced sign may include additional information that may be interpreted by an autonomous vehicle or a human operator. The additional information that may be processed by the onboard computing systems of the vehicle, along with information from the other sensors on the vehicle GPS information and other information about the pathway. The computing system may adjust one or more functions of the vehicle in response to vehicle pathway characteristics. The pathway articles of this disclosure may also have advantages in applications such as for vehicles operating in warehouses, factories, airports, airways, waterways, underground or pit mines and similar locations.
