How Permanent are Construction-Induced Adjustments in Commute Behavior? Change Persistence Six Months after the Fix I-5 Project in Sacramento, California
Temporary events may induce many changes in travel behavior, some of which may lead toward more sustainable commute patterns. But to what extent do those changes persist after the event concludes, and what influences some people to maintain the new behavior indefinitely while others return to their previous pattern as soon as possible? This study addresses these questions in the context of the reconstruction of Interstate 5 (Fix I-5) in downtown Sacramento in summer 2008. The study conducted an internet survey of commuters six months after the Fix was completed (N=2050), in which the study explored both temporary and permanent changes that respondents may have made during the Fix. After cleaning the data and analyzing some key descriptive statistics, we will develop discrete choice models of the key commute changes made, as a function of attitudes, socioeconomic characteristics, and the built environment. The results will provide insight into the factors distinguishing between temporary and permanent changes, which in turn may suggest strategies for shifting some environmentally beneficial changes from temporary to permanent.
