Abstract

A system includes a mobile platform that moves under remote and/or autonomous control, a sensor package supported by the mobile platform that obtains information relating to a component of a transportation network, and one or more processors that receive the sensor information and analyze the information in combination with other information that is not obtained from the sensor package. The processors also generate an output that displays information relating to one or more of a status, a condition, and/or a state of health of the component of the transportation network; initiates an action to change an operational state of the component; identifies a hazard to one or more vehicles traveling within the transportation network; and/or collects the information relating to the component. Optionally, the component is not communicatively coupled to an information network and the mobile platform provides the information obtained by the sensor package to the information network.

displays information relating to one or more of a status, a condition, or a state of health of the component of the transportation network,

initiates an action to change an operational state of the component,

identifies a hazard to one or more vehicles traveling within the transportation network, or

collects the information relating to the component,

wherein the component is not communicatively coupled to an information network, and the mobile platform provides the information that is obtained by the sensor package to the information network.

2. The system of claim 1, wherein the information relating to the component of the transportation network is one or more of a condition or a state of health of the component.

3. The system of claim 1, further comprising a control unit configured to control a path of travel of the mobile platform.

4. The system of claim 3, wherein the control unit is configured to autonomously prevent the mobile platform from moving outside of a determined multi-dimensional movement envelope or from moving into a restricted airspace.

5. The system of claim 3, wherein the control unit is further configured to respond to a signal from a beacon to avoid controlling the mobile platform into a collision with an object operably coupled with the beacon.

6. The system of claim 4, wherein the control unit is further configured to control the mobile platform to move to a safe position or operating mode in response to the mobile platform being located within a defined distance of a beacon or being located outside of the movement envelope.

7. The system of claim 4, wherein the control unit is further configured to communicate with an air traffic control system prior to controlling the mobile platform from moving from within the movement envelope to commercial airspace.

8. The system of claim 1, wherein the information obtained from the sensor package is video or image data;
