Trinium MC3 is a mobile app designed for truck drivers who work for intermodal trucking companies that use Trinium TMS (transportation management system) as their back office operating system. MC3 is installed on handheld devices for use by truck drivers. MC3 is an extension of the main Trinium TMS application, enabling improved productivity throughout the operation of the intermodal trucking company. MC3 functionality includes mobile dispatch workflow, document capture, signature capture, GPS tracking, and geofencing capabilities. MC3 is used by owner operators and employees drivers alike. To operate MC3, the trucking company must have active Trinium TMS and Trinium MC3 licensing or subscription agreements.
