1. A system comprising: a computing device configured to receive data associated with each of a plurality of packages being shipped in a delivery network, said data comprising dimensional information associated with at least one of the plurality of packages; a dimensional scanner configured to determine one or more dimensions of at least one of the plurality of packages; a scanner configured to scan a unique identification code displayed on each of the plurality of packages in order to identify in which of a plurality of trailers each of the plurality of packages is assigned and to transmit an identified trailer assignment associated with each of the plurality of packages; and a network entity in electronic communication with the computing device, dimensional scanner, and scanner, said network entity configured to: receive the data associated with each of the plurality of packages from the computing device, the one or more dimensions of at least one of the plurality of packages from the dimensional scanner, and the identified trailer assignment associated with each of the plurality of packages from the scanner; determine one or more dimensions of each package in a first subset of the plurality of packages based at least in part on some combination of the dimensional information of the data received from the computing device and the one or more dimensions of at least one of the plurality of packages received from the dimensional scanner; determine a volume of a second subset of the plurality of packages based at least in part on a weight of the second subset of the plurality of packages and historical average volume data; calculate, for each of the trailers in the plurality of trailers, an aggregate volume of the packages assigned to the trailer based at least in part on the identified trailer assignments, the one or more determined dimensions for the first subset and the determined volume of the second subset of each of the packages; and determine the utilization of each of the plurality of trailers based at least in part on the calculated aggregate volume of the packages assigned to each of the plurality of trailers.
