Reading Group: Changing commuter behavior to address traffic congestion

According to the latest U.S. Census Bureau figures, between July 2015 to July 2016, Seattle was the fastest growing city in the U.S., with a net gain of nearly 21,000 people or 57 per day, on average. With this considerable influx of residents comes an increased volume of vehicular traffic, further exacerbated by a geographically restricted mobility infrastructure.  Rush hour times have become extended, with Seattle ranked fourth among U.S. cities for the worst overall congestion levels.  Seattle commuters spend approximately 40 extra minutes per day (152 hours per year) sitting in traffic congestion.

In this reading seminar-style group, we will explore research that investigates methods of motivating people to change their commuting behavior as a way to reduce congestion levels. The research discussed in class will be used to guide the design of a next generation traffic communication app. Students will be responsible for reading approximately a dozen scholarly articles during the quarter as well as leading the discussion for one or two of these articles. For an example reading, see here. The anticipated workload is 3-5 hours of reading and one hour of in seminar discussion.  Please contact Sonia Savelli (, Sarah Yancey ( or Mark Haselkorn ( if interested in participating.
