The new GPS-enabled scanners that have recently been deployed to letter carriers of the U.S. Postal Service transmit digital “breadcrumbs” back to Postal Service delivery manager computers that can be used to find and retrace the steps of letter carriers making their appointed rounds. Many letter carriers have already been briefed on the capabilities of the new scanners, and warned to do their daily duties accordingly or risk being identified by the new Delivery Management System (DMS) software program. For example, carriers have been warned that spending more than five minutes with another carrier on the street will result in an alert on the delivery manager’s computer. The DMS program has a host of tracking tools, including creating alerts when a carrier is running late. One of the most powerful tools of the DMS software is the Breadcrumbs feature that plots letter carrier movements throughout the day. The feature can be used to find a carrier, or the data can be played back to see where the carrier was minute-by-minute throughout the day. For example, in the above image of the Breadcrumbs feature in the DMS, the carrier has just started his day in the 6400 block of Anita and he has delivered one side of the block and is halfway down the other side of the block. Additional digital “breadcrumbs” will be added to the map as the letter carrier progresses on the route. A delivery supervisor can play back these breadcrumbs, with the corresponding time shown, to get a detailed view of a carrier’s day.
