Benefit-cost analysis can be a powerful tool for informing infrastructure investment decisions. New York City’s Department of Transportation has been using this tool in the early stages of funding and design for select projects to identify alternatives that provide the greatest benefit to the public at the lowest cost. This talk demonstrates how the agency applied benefit-cost analysis on a major street redesign and on several bridge rehabilitation projects to save tens of millions of dollars while maximizing safety, mobility, and infrastructural benefits for the public. It also includes a discussion on how this benefit-cost analysis helped city government leadership select and fund the alternative that best advanced the city’s strategic objectives. The presenters will include senior executive management and the department’s policy office.
