Maintenance SOP 051: Update Yard Map


This procedure provides information for Yard Coordinators to use the CAD/AVL system to consistently  update yard maps for each service day. The process covers assigning vehicle status (availability) and entering vehicle locations. 

Operational Impact and Metrics 

Operational Impact: The Yard Map should be updated as vehicles return to the bus yard at the end of the operational day and for splits. This includes managing vehicle locations on the yard map and adding the status of that vehicle. Failure to update the yard map daily will lead to an increase in morning pullout time. 

WHY: Vehicles parked based on initial pullout needs, saves the agency time. Updating the Yard Map throughout the service day, to account for splits, etc., also ensures that vehicle availability  is known by dispatch and operators for seamless operation.

Metrics: Pull-in/Pull-out report - Business Intelligence
