Federal, state and local governments spend roughly 5 percent of their total expenditures on transportation: roads, bridges, tunnels, public transit, ports, etc. Such projects and programs are intended to support the efficient movement of people, goods and services, but also impact livability and other societal goals. The 2012 federal transportation reauthorization, MAP-21, is calling for more performance-based decision-making.

A recent research project examines transportation decision-making in six innovative states: California, Massachusetts, Minnesota, Tennessee, Utah, and Virginia.

This webinar will offer examples of current decision-making practices, note strengths and weaknesses, and highlight significant gaps in linking transportation investment decisions to outcomes.

Key takeaways include a suggested comprehensive framework for performance-based transportation decision-making and ideas for going beyond MAP-21.

Climate change caused by human activity is increasingly recognized as a threat to life on earth.

Despite the lack of a comprehensive national response to this threat, several states have already taken ambitious measures to combat climate change.

A new NITC report examines the approaches used in four leading states—California, Maryland, Oregon and Washington—to identify strengths and weaknesses of the transportation-land use-climate policy framework in each state, and to find opportunities for improvement.

Rebecca Lewis and Rob Zako of the University of Oregon just released their report, Assessing State Efforts to Integrate Transportation, Land Use and Climate

“States have been seen as laboratories of democracy, where we ground-test the ideas that might later apply at the federal level. States should be looking to learn from each other,” Lewis said. “States and cities are the ones taking action.”

The four states examined in this report are progressive in adopting state-level legislation to reduce emissions of greenhouse gases (GHG) from transportation.

Since the transportation sector accounts for almost one-third of all GHG emissions in the United States, transportation planners and policymakers have the ability to take...

Saddling transit-oriented developments with parking requirements better suited to typical suburban developments can make housing and office space near transit scarce and overly expensive. That’s one implication of a NITC research report examining driving and parking at these centers.

It makes sense that transit-oriented developments—dense, walkable centers close to transit that combine residential, commercial and office uses—would generate fewer car trips and need less parking than other development types. But until now, no one has found out how much less parking.

NITC researcher Reid Ewing of the University of Utah took up the challenge and reveals the answer in a report: a lot less. The developments Ewing’s team studied generally generated less than half the driving, and required fewer than half the parking spaces, than standard guidebooks predict. They presented some of their findings Jan. 10 during the annual meeting of the Transportation Research Board in Washington, D.C. Learn more about the conference or download the paper.

Ewing’s team studied transit-oriented developments in five United States metropolitan areas and found the...

States can reduce greenhouse gas emissions with a broad range of approaches, but none will have much luck without continued support from leaders and the public, according to NITC program research from the University of Oregon. In a conference paper for the annual meeting of the Transportation Research Board in Washington, D.C., a team led by Rebecca Lewis took a close look at the efforts West Coast states have made to reduce emissions from the transportation.

Cutting transportation emissions depends on three variables: vehicle efficiency, fuel carbon content and vehicle miles traveled, or VMT. The paper focuses on the last leg: cutting driving. While more efficient automobiles and alternative fuels have come on the market in recent years, a growing population and longer commutes can wipe out any emissions gains from shifts in fuel economy and fuel type.

Washington, Oregon and California have all passed statutes to cut statewide greenhouse gases below 1990 levels by 2020. The approaches vary in their targets, plans and strategies.

Lewis and her team present the research in a poster session Tuesday, Jan. 12 at the annual meeting of the Transportation Research Board in...
