More and more parking has been a constant mandate for modern urban transportation planning. But several trends point to a big drop in the need for parking spaces, say experts including Mikhail Chester, a Fulton Schools associate professor of civil, environmental and sustainable engineering. Chester was among researchers at ASU and the University of California, Berkeley, who estimated of the numbers of parking spaces in the U.S. compared to the number of passenger vehicles. Researchers say that with more shared autonomous vehicles, robotaxis and micro-mobility devices, along with remote working and lower rates of car ownership among younger generations, the demand for more parking spaces will almost certainly dwindle.
