Public transit equipment and facilities management system (PTMS)

Public Transit prioritizes vehicle replacement and rehabilitation/remanufactured projects annually on a statewide basis based on age and mileage of existing vehicles compared to useful life standards for the specific type of equipment.


  • Accumulated mileage minus standard fleet mileage divided by 3,500 equals mileage score
  • Actual months owned minus fleet life months equals age score
  • Mileage score plus age score equals vehicle score
