Less than two months after President Donald Trump pledged in his State of the Union Address to "rebuild our crumbling infrastructure," prospects look dim. The Trump administration is asking Congress for ideas about how to fund trillions of dollars in improvements that experts say are needed. Some Democrats want to reverse newly enacted tax cuts to fund repairs – an unlikely strategy as long as Republicans control Congress.
Deciding how to fund investments on this scale is primarily a job for elected officials, but research can help set priorities. Our current work focuses on transit, which is critical to health and economic development, since it connects people with jobs, services and recreational opportunities.

Along with other colleagues at the Urban Information Lab at the University of Texas, we have developed a website showing which areas in major U.S. cities do not have sufficient alternatives to car ownership. Using these methods, we have determined that lack of transit access is a widespread problem. In some of the most severely affected cities, 1 in 8 residents lives in what we refer to as transit deserts.
