Evaluation methods for rail transit projects [PDF]
Transportation Research Part A: General, 1989 The demand for rail transit funds greatly exceeds available monies. Worse, there is widespread disagreement over the wisdom of building rail systems in American cities. The Urban Mass Transportation Administration's (UMTA's) transit analysis methods have relied on cost-effectiveness measures with little attention devoted to the analysis of economic ...
