Trying to find a place to park downtown is often pretty hard. With too many cars chasing too few parking spaces, the result is too much congestion and pollution, not to mention the aggravation that goes with finding a place to park. As much as 30 percent of downtown traffic can be attributed to drivers circling streets in search of a spot, according to the International Parking Institute.
Parking garages help, but they're expensive. They can cost anywhere from $20,000 to $50,000 per parking space, based on development and construction costs, and are usually subsidized, so drivers never pay the true cost to park, according to Norman Garrick, a professor of civil and environmental engineering at the University of Connecticut.
