Alan Pisarski, author of “Commuting in America III,” visited PSU in October 2006 as part of the OTREC Visiting Scholar Program. Pisarski is a transportation expert known for his major studies of American commuting patterns. During his visit, he spoke at a Womenís Transportation Seminar (WTS) breakfast meeting, visited with students in the PSU ITS Lab, and was the guest speaker for the weekly CTS Transportation Seminar. Pisarski summarized changes and trends in commuting patterns in the United States and noted such statistics as lengthening average daily commutes, (many are more than 90 minute or ìextremeî commutes), increase in carpooling and transit use, shifts in city to suburb vs. suburb to city commuters and increase in numbers of people working at home. Pisarskiís research shows that transportation is influenced significantly by economic and social phenomena.
