Vehicle Operator SOP 020: Pullout/Start of Shift


This procedure provides information for bus operators to use the MDT of the CAD/AVL system during pull-out or at the start of their shift. This procedure assumes the schedule has been pushed to the on-board CAD/AVL system. The process covers check-in, pre-trip start up and inspection, and vehicle pull-out.  

Operational Impact and Metrics 

Operational Impact: The CAD/AVL system streamlines several common pull-out tasks and helps identify and address problems and improve on-time performance by tracking operator dispatch window check in time, MDT log in time, and pull-out time. The system provides alerts to dispatchers if operators have not hit goal times and allows dispatch to provide relief operators quickly. 

Metrics: Operator check-in time, Operator MDT log-in time, On-time pull-out %
