For the first time, researchers have shown that installing light rail on an existing travel corridor not only gets people out of their cars, but reduces congestion and air pollution.
In the study, planners at the University of Utah measured impacts of a new light rail line in Salt Lake City (University Line) on an existing major thoroughfare (400/500 South). Their analysis showed that traffic near the University has fallen to levels not seen since the 1980s, even as the number of students, faculty and staff at the university has increased, and the commercial district along the corridor has expanded.
"This is the first study to document important effects of light rail transit on traffic volumes,” said Reid Ewing, professor of city and metropolitan planning at the University of Utah and lead author on the study. “Since the University TRAX line opened, there has been increased development in the 400/500 South travel corridor, yet traffic on the street has actually declined. Our calculations show that without the University TRAX line, there would be at least 7,300 more cars per day on 400/500 South, and possibly as many as 21,700 additional cars. The line avoids gridlock, as well as saves an additional 13 tons of toxic air pollutants. This is important knowledge for shaping future transportation policies.”

The NITC program's executive committee has selected a new roster of projects for funding under the National Institute for Transportation and Communities, or NITC, program. The committee chose 10 projects, totaling $900,000, under the NITC theme of safe, healthy and sustainable transportation to foster livable communities.
The projects are national in scope and reflect priority areas including transit supply and outcomes, and pedestrian and bicyclist behavior.
Projects selected include:
- A bicycle and pedestrian miles traveled project for Washington state.
- A study that measures the effectiveness on social media on advancing public transit.
- A look into crowdsourcing the collection of data on transportation behavior.
- A national study of Bus Rapid Transit outcomes.
A complete list of projects and principal investigators is below:
- National Study of BRT Development Outcomes: Arthur Nelson and Joanna Ganning, University of Utah
- Crowdsourcing the Collection of Transportation Behavior Data: Christopher Bone, Ken Kato and Marc Schlossberg,...
