Abstract
A method for cross read mitigation in a monitoring station for vehicles carrying respective wireless tags having tag identifiers includes: receiving, from a first tag sensor disposed to detect wireless tag signals in a first lane of the monitoring station, a first tag read containing a tag identifier; receiving, from a second tag sensor disposed to detect further wireless tag signals in a second lane, adjacent to the first lane, of the monitoring station, a second tag read containing the tag identifier; in response to receiving the first and second tag reads, providing an updated tag detection parameter to each of the first and second tag sensors; receiving, from one of the first and second tag sensors, a third tag read containing the tag identifier; and in response to receiving the third tag read, instructing the one of the first and second tag sensors to report the tag identifier to a monitoring server.
