Personal rapid transit (PRT) has faced some challenges, says Curtis Johnson, not the least of which is the U.S.'s lack of "moonshot-mojo".
Johnson says that PRT is "appealing and affordable". So why isn't PRT getting built?
Johnson says that early versions have been lacking, and that development can take a long time. But there are also a number of roadblocks on the outside:
"Policy and its feisty cousin, politics, are the biggest barriers (haven't we all noticed?) to doing anything new, not already proven. Transportation policy basically operates to protect existing systems - roads and mass transit. Protectors of both line up with legislators to stand guard at the gate, warding off any threat to the pool of ever-scarcer resources. Understandably, they want to add to what they have and hold on to what they've got."
