Surface Visibility (SV) may sound like a nautical or even aeronautical term, but to the U.S. Postal Service it refers to multiple systems integrated to scan and track mail transported within the postal network. In fact, if you've ever used USPS Tracking to find where a package is, SV scanning has helped provide the answer.
It takes a lot of vehicles to move 154 billion pieces of mail each year. And a lot of fuel to power those vehicles.
While the Postal Service’s Postal Vehicle Services (PVS) fleet is a small part of the entire fleet — about 4,300 vehicles made up of cargo vans, tractors, and smaller tractor-trailers known as spotter vehicles — it is a crucial part. PVS vehicles move mail between processing facilities, inner-city delivery offices, and local businesses and mailers. Their usual travel distance is about a 50-mile radius.
As package volumes climb, so too has the U.S. Postal Service’s investments in sorting systems. Since 2015, it has deployed 33 Small Package Sorting System (SPSS) machines costing over $141 million. It intended to invest another $23 million to have seven more SPSS machines operational during the current holiday season.
