Personal Transportation Factsheet by the University of Michigan
In a new study, researchers at the University of Michigan looked at data on changes in vehicle miles traveled (VMT) from 2005 to 2015 for large cities across the United States (University of Michigan, 2021). They found that the average VMT per person declined by about 5 per cent during that period. The researchers also found that the decline in VMT was not uniform across all cities. Some cities, such as San Francisco and Seattle, saw much larger declines than others. The study’s authors say that the findings could have implications for transportation planning and policy. They say that if the trend of declining VMT continues, it could lead to less congestion and fewer emissions. The study was published in the journal Nature Sustainability.
