Abstract
A materials handling vehicle operating system is provided comprising a tag layout where a plurality of entry/exit tag sets are arranged along a travel path at different ones of the entry/exit thresholds of a restricted navigation zone. Each entry/exit tag set comprises a release tag, a restriction tag, and an indicator tag. The indicator tag is positioned between the restriction tag and the restricted navigation zone. The restriction tag is positioned between the release tag and the indicator tag. The tag reader and the reader module cooperate to compare identified tag data with stored tag data and initiate a remediation operation when an indicator tag is identified in place of a restriction tag. Tag layouts for one-way and two-way travel into and out of a restricted navigation zone are also contemplated.
