Abstract
A system and process for detecting a traffic lane boundary before it is potentially violated by a moving vehicle traveling in the lane. Passive RF tags or labels are embedded in a paint stripe running along pavement. A sensor in the vehicle emits an RF signal at a frequency to which the tags or labels are responsive. When the emitted signal is incident on a tag or label with strength indicative of straying of the vehicle from the lane toward incipient violation of the lane boundary defined by the stripe, the tag or label issues a return signal that is received by the sensor for on-board signaling of the potential violation to alter the driver so that corrective action can be taken.
