Abstract
A pneumatic carrier system is provided for distribution and transport of materials between different locations. The system includes a plurality of carriers for conveyance of materials and a control system for controlling the movement of the carriers in the system. The control system uses information associated with the carriers and the status of areas of the system to detect gridlock conditions which inhibit the movement of carriers. The system also includes bypass locations which are used to resolve detected gridlock conditions.
