Over the last decade, NYSDOT has made important strides in improving the condition and efficiency of its infrastructure. For instance:
|Economic analysis is contributing to a more dynamic and accountable decision-making process within NYSDOT. At the program and project levels, economic methods will play an essential and larger role within the TAM framework.|
NYSDOT has not, however, completed a formal study of the specific contribution attributable to economic analysis techniques to this improved performance. The application of economic analysis to infrastructure investment decisions has developed gradually over time, making it difficult to define a before-and-after case study. In addition, it is problematical to separate the impact of economic analysis from important managerial and process reforms and higher funding levels introduced during the last 15 years. Finally, a significant innovation made by NYSDOT--the TAM Tradeoff Model--has not yet been incorporated into the decision-making process.
There is recognition within NYSDOT, however, that economic analysis is contributing to a more dynamic and accountable decision-making process. In May 2003, five years after the development of its "Blueprint," NYSDOT announced the adoption of TAM as the framework for managing all infrastructure investments. Economic methods at both the program and project levels will play an essential and larger role in this framework.
