Optimizing Highway Transportation at the United States Postal Service

The United States Postal Service (USPS) delivers more than 200 billion items per year. Transporting these items in a timely and cost-efficient way is a key issue if USPS is to meet its service and financial goals. The Highway Corridor Analytic Program (HCAP) is a tool that aids transportation analysts in identifying cost saving opportunities in the USPS surface transportation network. Use of this tool is resulting in millions of dollars of annual savings.
