Title: VALUE OF URBAN TRANSIT OPERATING-COST MODELS AS FORECASTING TOOLS

Availability: Find a library where document is available Abstract: Eight urban transit operating-cost models were reviewed to determine their value as forecasting tools. The models were found to have structural problems. In the average-daily-cost model and annual-cost model, the association inputs with outputs was assumed to have a strong positive correlation. Case-study transit system data were used to test these relationships. The findings indicate that these two models were not reliable because strong positive correlations existed in too few of the expected relationships. The eight models were not designed to include variables that measure the influence of institutional factors on operating costs. The necessity to subsidize transit operations has led to increasing involvement of the public sector in transit operating decisions. Planners are advised to refrain from relying totally on any of the eight models for estimation of operating costs. Such additional techniques should be considered as developing probabilities of changes in cost categories and generating alternate scenarios of operating conditions. (Author)
