Recent articles in Medium and Sightline highlighted the findings of Associate Professor of Urban Planning Adam Millard-Ball’s new research on the relationship between parking and driving in cities. While many cities have been designed under the assumption that the urban environment should accommodate people’s desire to drive, researchers led by Millard-Ball found that that assumption is backward. “Increased parking causes more car ownership and more driving while reducing transit use,” the team concluded, noting that “buildings with at least one parking space per unit have more than twice the car ownership rate of buildings that have no parking.” The Sightline piece cited Urban Planning Professor Donald Shoup’s observation that parking spaces are a “fertility drug for cars.” Furthermore, the research team found no correlation between parking supply and employment status, indicating that buildings with less parking do not limit the job prospects of their occupants.
