Converting unused parking spaces in active areas for the city

In the United States, car ownership, driving and parking have been an enormous issue in the way cities have come to be since were developing when car ownership was getting more and more common. The reality today is that there is an excessive quantity of space dedicated to parking: it’s estimated that in some cities of United States, one third of the surface is taken up by parking surfaces.
Parking dominates the landscape in the United States because there was a need, and there was land. In the future driverless environment, the impact of self-driving vehicles on parking lots will be so heavy that will be not more necessary their presence. If the majority of trips is by continuously moving shared vehicles, the need is for drop-offs and not for on-street parking. Consequently, if there is less demand for parking, areas typically reserved for that service could be transformed into housing or office space. This will permit to achieve more spaces for mixed use buildings complexes and therefore create compact and dense urban areas in which pedestrians are the leading actor.
