Roadway information detection systems consists of sensors on automonous vehicles and devices for the road

A system comprising:

• a vehicle comprising a first processor, a first memory storing first executable instructions for execution by the first processor, a control system, a navigation system and a first transceiver operating according to a predetermined wireless protocol;
• a plurality of devices deployed with respect to a section of roadway;
• wherein
• a first subset of the plurality of devices are active devices, each active device of the plurality of devices associated with a predetermined element of the roadway comprising a second processor, a second memory storing second executable instructions for execution by the second processor and second transceiver operating according to the predetermined wireless protocol;
• a second subset of the plurality of devices are passive devices, each passive device of the plurality of devices associated with a predetermined element of the roadway;
• the first executable instructions when executed by the first processor configure the processor to execute a first process comprising:
• transmit a discovery signal from the first transceiver;
• receive data via the first transceiver from a device of the plurality of devices, the data generated by a device of the plurality of devices in response to the discovery signal and transmitted as a response signal;
• process the received data to determine whether first information with respect to the roadway has been received and second information with respect to the roadway has been received;
• determining whether first information was received within the processed received data and upon a positive determination passing the first information to the control system for controlling an aspect of the vehicle;
• and
• determining whether second information was received within the processed received data and upon a positive determination passing the second information to the navigation system;
• the second executable instructions when executed by the second processor configure an active device to execute a second process comprising:
• receive the discovery signal from the first receiver;
• compile data for transmission in dependence upon the element of the roadway with which the active device is associated;
• and
• transmit the compiled data with the second transceiver as the response signal.
