Roadway information detection sensor device/system for autonomous vehicles

A method comprising:

• providing a radio frequency (RF) module forming part of an autonomous vehicle comprising one or more RF transmitters and one or more RF receivers;
• wherein
• the one or more RF transmitters transmit radio frequency (RI) signals from the autonomous vehicle;
• and
• the one or more RF receivers received reflected RF signals, the reflected RF signals being reflected from a plurality of passive road markers disposed upon a surface being traversed by the autonomous vehicle, each passive road marker of the plurality of passive road markers being in a predetermined spatial relationship to the remainder of the plurality of passive road markers;
• and
• providing a hub forming part of the autonomous vehicle which executes a process comprising:
• processing the reflected RF signals received from the plurality of passive road markers to establish lane marker information, the established lane marker information comprising relative distances of each passive road marker of the plurality of road markers from the autonomous vehicle;
• and
• determining in dependence upon the processed reflected RF signals received from the plurality of road markers a position of the autonomous vehicle relative to the plurality of road markers;
• wherein
• the plurality of passive lane markers comprises passive lane markers defining a current lane the autonomous vehicle is currently travelling within and other passive lane markers defining one or more lanes over from the current lane.
