Accuracy of Surface Visibility Scans and Reporting

The objective of our audit was to evaluate the accuracy of Surface Visibility scans and reporting for Highway Contract Route (HCR) and Postal Vehicle Service (PVS) trips. This audit was requested by the Postal Service’s Surface Logistics group. Surface transportation includes HCR, PVS, maritime, and rail service contracts. The Postal Service uses HCRs to transport mail and other products between plants and other designated stops for distances generally over 50 miles. PVS operations are internally operated by the Postal Service and trips are generally within a 50-mile radius of Postal Service facilities.
