Dispatch SOP 013: Pullin/End of Shift


This procedure provides information for dispatchers, or other appropriate transit agency staff, to best use the CAD/AVL system for common items occurring at pull-in or at the end of their shift or service. This procedure assumes the schedule has been pushed to the on-board CAD/AVL system (See SP-001-01). The process covers monitoring and managing operator scheduled and actual pull-in times, operator log out, post-trip inspections, yard location, and event recording. 

Operational Impact and Metrics

Operational Impact: The CAD/AVL system streamlines several common pull-in dispatch tasks and helps identify and address problems and improve on-time performance. By having access to yard maps, operator information, vehicle status information, and various monitoring alerts, Dispatchers can make quick adjustments to achieve on time pull-in. 

Metrics: On-time pull-in %
