Materials handling vehicle operating system comprising remedial indicator tags

A materials handling vehicle operating system comprising a materials handling vehicle, a tag layout, a tag reader residing on the materials handling vehicle, a reader module, and a vehicle controller, wherein:

• the materials handling vehicle comprises storage and retrieval hardware and a vehicle drive mechanism;
• the tag layout comprises a plurality of sequenced tags positioned along a travel path comprising a restricted navigation zone;
• the restricted navigation zone comprises an entry threshold and an exit threshold along the travel path;
• the sequenced tags comprises an entry tag set arranged along the travel path at the entry threshold of the restricted travel zone and an exit tag set arranged along the travel path at the exit threshold of the restricted navigation zone;
• the entry tag set comprises a restriction tag and an indicator tag;
• the exit tag set comprises a release tag;
• the indicator tag is positioned between the restriction tag and the restricted navigation zone along the travel path;
• the restricted navigation zone is positioned between the indicator tag and the release tag along the travel path;
• the tag reader and the reader module cooperate to identify the release tag, the restriction tag, and the indicator tag of the sequenced tags of the tag layout;
• the vehicle controller executes restricted or unrestricted operational functionality of the materials handling vehicle in accordance with the identification of the restriction tag and the release tag along the travel path by the tag reader and the reader module;
• and
• the tag reader and the reader module further 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 according to a sequenced portion of the stored tag data.

A materials handling vehicle tag layout comprising a plurality of sequenced tags positioned along a travel path comprising a restricted navigation zone, wherein:

• the restricted navigation zone comprises a plurality of entry/exit thresholds along the travel path;
• the sequenced tags comprise a plurality of entry/exit tag sets arranged along the travel path at different ones of the entry/exit thresholds of the restricted navigation zone;
• each entry/exit tag set of the plurality of entry/exit tag sets 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 along the travel path;
• and
• the restriction tag is positioned between the release tag and the indicator tag along the travel path.
