Purpose
This procedure provides information for vehicle operators for how to use the MDT during revenue service. This procedure assumes the schedule has been pushed to the in-vehicle CAD/AVL system. The process covers adherence to schedule, reporting schedule issues, communicating with Dispatch, using emergency alarms, fare collection, and various possible in-service events.
Operational Impact and Metrics
Operational Impact: The CAD/AVL system streamlines several common operator tasks during service and helps identify and address problems as routes are running and efficiently provide relief operators or replacement buses as necessary.
Metrics: On-time performance, Vehicle capacity, Bus bunching on route

Video Tagging
- Use during hostile situations ( as defined by agency policy and practice)
