Sustainable Transportation Concepts:
A Mini-Lecture Series from the NCST

The NCST is excited to announce a new series of recorded mini-lectures on sustainable transportation from our faculty and researchers! These short videos will be available for professors to use for free! in their courses as supplemental lectures.

Check out our first mini-lecture from the NCST's Director, Dr. Susan Handy, "Sustainable Transportation Concepts: A Mini-Lecture Series from the NCST," and keep an eye out for more soon!

A New Web Tool to Calculate Induced Travel
Thursday, May 23, 2019, 10:00am – 11:00am PDT

Speaker: Jamey Volker | Ph.D. Candidate, Transportation Technology and Policy Program, UC Davis
Guest Respondents: Chris Ganson | Senior Advisor for Transportation, Governor's Office of Planning and Research; and Gordon Garry | Senior Staff, Sacramento Area Council of Governments (retired)

Attempts to address traffic congestion commonly rely on increasing roadway capacity, e.g., by building new roadways or adding lanes to existing facilities. But studies continue to show that adding capacity is at best a temporary fix: adding roadway capacity in congested areas actually increases network-wide vehicle miles traveled (VMT) by a nearly equivalent proportion within a few years, which reduces or negates any initial congestion relief. That increase in VMT is called “induced travel.” The induced travel effect is explained by bedrock economic principles of supply and demand: adding roadway capacity reduces travel time; and as that effective “price” of driving goes down, the quantity of driving increases. The magnitude of that increase is commonly measured as the elasticity of VMT with respect to lane miles. Studies generally show that a 10-percent increase in roadway capacity is likely to increase network-wide VMT by 6 to 10 percent (an elasticity of 0.6 to 1.0). Yet methods of calculating project-level induced travel frequently vary and are often opaquely explained in transportation impact studies. NCST researchers developed a 
web-based induced VMT calculator to help with that. 

This webinar will:

  • Give an overview of the induced travel concept;
  • Summarize the academic research on induced travel elasticities;
  • Introduce the new induced VMT calculator developed by NCST researchers; and
  • Provide discussion on the calculator from two California transportation planning and policy experts.
Incorporating Long-distance Travel into Transportation Planning in the United States
Speaker: Dr. Lisa Aultman-Hall  | University of Vermont
Guest Respondants: Rebekah Straub Anderson | Ohio DOT Office of Statewide Planning and Research; and Karen Faussett | Michigan DOT Office of Statewide and Urban Travel Analysis

This webinar presents information regarding changes in demand for long distance travel over time as well as the relationship between long distance travel and sustainability. Dr. Aultman-Hall also touched on prior long-distance travel research and provided a framework for moving forward with long-distance travel data collection.

Applications of Integrated Energy and Emissions Modeling Tools
Speakers: Dr. Randall Guensler & Ph.D Student Hanyan (Ann) Li Georgia Institute of Technology

This webinar presented an overview of the various NCST-supported modeling tools that allowed the research team to model on-road and lifecycle energy use and emissions for a U.S. Department of Energy ARPA-TRANSNET project.

NCST's Leadership Council

The NCST convened its Leadership Council in March 2019 in Davis, California, and took a new, more engaging approach to the meeting. The NCST Leadership Council provides guidance on research priorities and project design to maximize impact and assists with translating research findings into actionable strategies and policies. Participants, including NCST faculty, researchers, students, and staff, engaged in a series of roundtable discussions and think tanks to discuss policy, research, and stakeholder engagement.
