Effectiveness of Transportation Funding Mechanisms for Achieving National, State and Metropolitan Economic, Health and Other Livability Goals

Rob Zako Rebecca Lewis
The Moving Ahead for Progress in the 21st Century Act (MAP-21), adopted in 2012, established national performance goals for Federal-aid highways in seven areas. (Federal Highway Administration, n.d.) MAP-21 requires states and metropolitan planning organizations (MPOs) to establish performance-based planning processes, set targets (performance measures), and link planning and funding to these targets. States and MPOs have different mechanisms for allocating funding from various sources to… Read More

Developing Data, Models, and Tools to Enhance Transportation Equity

Amy Lubitow Julius McGee , Raoul Liévanos
Data from travel surveys are used to forecast demand, inform transportation investments, and craft urban policies. Because these data are so essential to shaping our transportation system, it is critical that hard-to-reach populations—such as low-income, minority, and transit-dependent people—have their travel behavior accurately reflected. The limited survey coverage may lead to inaccurate estimation of their transportation access and behavior, impede policy changes related to transportation… Read More
