Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online at 11:30 AM. Stay tuned for an announcement of the fall term lineup.

THE TOPIC 

Empirical research shows that expanding roadway capacity induces more driving - the so-called "induced travel" phenomenon. However, environmental impact assessments and cost-benefit analyses of roadway capacity expansion projects have historically ignored, underestimated, or mis-estimated this induced travel effect. As a result, they frequently overestimate the projects' potential to relieve congestion and reduce air pollution. That spurred our team at the National Center for Sustainable Transportation (UC Davis) to develop an online tool to facilitate estimation of induced vehicle travel from capacity expansion projects. This presentation will explain the induced travel phenomenon, introduce our induced travel calculator and its offshoots, and discuss how transportation impact analysis is changing.

KEY LEARNING OUTCOMES

The audience will hopefully walk away with an understanding of:

  • the induced travel phenomenon,
  • how the induced travel calculators work, and
  • how they are helping change transportation impact analysis.

SPEAKER
