APTS06-Transit Fleet Management (Service Package*)

Description

This service package supports automatic transit maintenance scheduling and monitoring. On-board condition sensors monitor system status and transmit critical status information to the Transit Management Subsystem. Hardware and software in the Transit Management Subsystem processes this data and schedules preventative and corrective maintenance. The service package also supports the day to day management of the transit fleet inventory, including the assignment of specific transit vehicles to blocks.

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

  1. To automate the maintenance of the transit vehicles, the TRMS sends a request to the Transit Vehicle Subsystem (TRVS) for vehicle performance and maintenance data collected by on-board sensors (request for vehicle measures). The TRVS responds with data containing vehicle performance and maintenance data collected by onboard sensors (transit vehicle conditions). Some of this data is obtained from sensors or systems in the Basic Transit Vehicle (the non-ITS portion of the transit vehicle) as transit vehicle measures.

  2. Transit Operations Personnel manage the overall process of transit vehicle management, inputting transit maintenance requirements, requested maintenance actions, as well as initializing and updating a vehicle assignment (as part of transit operations personnel inputs) to the Transit Management Subsystem (TRMS). The overall status of vehicle's activities as well as status of individual vehicle maintenance would be presented to the Transit Operations Personnel (as a part of transit operations status).

  3. At the beginning of a work day or shift, TRMS will send the transit schedule information to the TRVS in order to initialize the transit vehicle with a vehicle assignment to a particular block, monitor schedule performance, and develop corrective actions on-board.
