Abstract: A method includes receiving a request associated with loading or unloading of cargo at a terminal. The method also includes determining a recommended slot in response to the request, where the recommended slot includes a time slot for loading the cargo onto a cargo vehicle or unloading the cargo from the cargo vehicle. In addition, the method includes transmitting the recommended slot for delivery to a mobile device of an operator of the cargo vehicle. The method may also include receiving a signal from the mobile device to open an entrance of the terminal when the cargo vehicle arrives at the terminal and, in response to the signal, opening the entrance of the terminal to allow the cargo vehicle to enter the terminal. The method may further include, upon completion of the loading or unloading of the cargo at the terminal, wirelessly transmitting a digitally-signed document to the mobile device.
