Public transit agencies, like everyone else, must try to balance their expenses and incomes. Faced with an anticipated vehicle replacement shortfall of more than $200 million in the next 10 years, the Los Angeles County Transportation Commission, in conjunction with 13 Los Angeles County transit operators, conducted a study to develop cost-effective vehicle replacement guidelines. The study built on the results of research recently completed under an Urban Mass Transportation Administration-sponsored program directed by the Transportation Research Board under the National Cooperative Transit Research and Development Program. The result was a simple, efficient method for evaluating cost impacts of alternative vehicle replacement schedules. The method is presented in this article, along with guidelines for its application. When the guidelines were applied to each bus fleet owned by the 13 Los Angeles County transit operators, the alternative replacement schedules produced an estimated cost saving of $117 million (in 1989 dollars) over 10 years. When the guidelines were applied to the van and support vehicle fleets, the alternative replacement schedule, which required replacing the vehicles earlier than planned, produced an estimated cost saving of about $8 million.
