1. A device for a transportation vehicle, the device comprising:
one or more interfaces configured to communicate with other transportation vehicles in which messages are transmitted and received; and
a data processing circuit configured to:
receive environment information relating to an environment of the transportation vehicle in a message from another transportation vehicle via the one or more interfaces,
validate whether the received environment information is reliable and, based on the validation, generate reliability information indicating a determination of a degree of reliability validation having been determined by the data processing circuit for the environment information, wherein the validation comprises automatic comparison of the environment information with sensor data from at least one sensor of the transportation vehicle performed in response to receipt of the environment information,
embed the validated environment information and the generated reliability information in a message for transmission with control information and payload; and
transmit the validated environment information along with the generated reliability information to the other transportation vehicle,
wherein the validated environment information is assigned to the payload of the transmitted message and the generated reliability information is assigned to the control information of the transmitted message,
wherein the control information also includes an identifier assigned to the message, wherein the identifier and the generated reliability information in the control information of the transmitted message are analyzed by transportation vehicles receiving messages to determine an extent to which received messages with the same identifier require decoding and whether the received messages include environment information that requires validation based on whether the environment information has been previously validated by other transportation vehicles prior to receipt by the transportation vehicle,
wherein the generated reliability information indicates the determination of the degree of reliability validation having been determined for the environment information by a validity counter that indicates a number of times that the environment information has been validated at other vehicles,
wherein the validity counter is incremented prior to transmission of the message to other transportation vehicles in response to the environment information being validated by the comparison with sensor data from at least one sensor of the transportation vehicle performed in response to receipt of the environment information,
wherein the validity counter is decremented prior to transmission of the message in response to other transportation vehicles in response to the environment information in the message being refuted by the comparison with sensor data from at least one sensor of the transportation vehicle performed in response to receipt of the environment information, and
wherein selection of at least one sensor of a plurality of sensors on the transportation vehicle for gathering environmental information for use in autonomous or partially autonomous driving of the transportation vehicle is based in part on the degree of reliability validation previously determined by other transportation vehicles prior to receipt by the transportation vehicle.
