Sollohub, a New Jersey Institute of Technology professor who studies parking and urban land use. ''It may provide one of the solutions to the most important conflict in urban design: where do you put all the cars in environments where car volume is high and space is at a premium?''

“Although an automated garage is more expensive to build it typically takes only about half as much precious real estate as a conventional ramped garage to handle the same number of cars, or even more. That is why in European and Asian cities, the automatic garage was long ago anointed as the best solution, Mr.
Sollohub said. “

“Urban land use specialists say that this sort of situation will continue to occur in congested American cities, and that automated parking could become a widely used option.”
