Claim 0:
1. A barrier transfer machine for picking up and repositioning a plurality of road barriers, the barrier transfer machine comprising:
an entry snout for picking up the road barriers from a road surface;
an exit snout for placing the road barriers back onto the road surface;
a conveyor system positioned between the entry snout and the exit snout for transporting the road barriers from the entry snout to the exit snout; and
a tracking system for tracking a location of each of the road barriers as it is placed onto the road surface, the tracking system comprising:
a location sensor mounted on the barrier transfer machine for sensing the location of each of the road barriers as is it placed onto the road surface;
a memory configured to retain location data representative of the location of each of the road barriers as it is placed onto the road surface and temporal data representative of at least one of a date and time of placement of the road barriers onto the road surface so that the temporal data is mapped to the location data, the location data for each of the road barriers including a plurality of coordinates corresponding to ends and a center of the road barrier; and
a processing system in communication with the location sensor and the memory, the processing system being configured to:
store the location data and the temporal data on the memory as a first entry;
generate a searchable log of the location data and temporal data via the memory;
add location data and temporal data to the searchable log each time the road barriers are repositioned on the road surface while retaining all previously stored location data and temporal data such that the searchable log forms an evidentiary chain of locations of the road barriers going back to the first entry;
after the road barriers have been repositioned on the road surface, query the searchable log via the temporal data; and
output location data based on the query for determining a location of one of the plurality of road barriers at a temporal point represented by the temporal data.
