Major transit projects can have profound effects on nearby businesses. Although much research has investigated physical neighborhood changes and neighborhood demographic changes driven by transit projects, little is known about the perceived effects of transit projects in business communities. In a direct response to this knowledge gap, a random-sampled survey of 160 businesses was conducted along four existing and planned transit corridors in the Twin Cities region in Minnesota. With the survey responses, ordered logistic regression models of business perceptions of transit corridor projects were estimated. It was found that responding businesses generally expect positive effects from transit corridors in the future, but the likelihood of positive perceptions differs significantly according to business location, size, and sector, as well as employees' and customers' demographics and customers' travel behavior. These findings provide insights into the types of businesses to target for special outreach efforts as well as strategies for mitigating negative effects and maximizing positive effects perceived by station area businesses.
