Abstract: Retroreflective articles comprise a substrate and a bar code provided on the substrate. The bar code comprises at least one human-readable information which provides framing information and a machine-readable information which provides variable information. The human-readable information is visible under a first condition and invisible under a second condition, and the machine-readable information is invisible under the first condition and visible under the second condition.

Abstract: Disclosed is an identification system to improve safety on roads and allow for the driver or for the vehicle itself, if it is autonomous or semi-autonomous, to have readable and useful information about road signs, roadways, and adjacent roadway information. The disclosed identification system comprises a marker with marker communication information that can be read by a vehicle information system to provide information to the vehicle. Information that the marker communication information may convey would allow the vehicle information system to detect or recognize, or both detect and recognize critical road sign, roadway information, and adjacent roadway information. Then, the vehicle information system could respond to the information received from the marker communication information.
