4.1.1: Process On-Board Systems Data

This process shall collect and process data available to sensors and systems on-board transit vehicles. This data includes on-board data (such as the status of on-board systems), passenger count as they board and exit the vehicle, and collected trip data. This data shall be sent by this process to other processes on-board the transit vehicle and elsewhere in the Manage Transit function for use in determining vehicle schedule deviations and for storage as operations data. This process shall also collect and process vehicle maintenance data available to sensors on-board transit vehicles. When processed, the data shall be sent by this process on request to another process in the Manage Transit function for storage as transit vehicle operating data so that it can subsequently be used for work on future vehicle maintenance.

This process is associated with the Transit Vehicle OBE physical object.
