The impacts of AVs and TNCs on the future of transportation remains unknown. The benefits of AVs could be important, and investments taking place in the industry have been staggering. Changes to transportation will vary based on geographic region, and will be impacted by consumer acceptance, cost of the technology, and infrastructure readiness. Walker estimates that the reduction of parking demand could be as low as 10 percent and as high as 40 percent by 2050. Because much remains unknown, planners should consider solutions which are adaptable, like right-sizing parking projects, adaptive reuse of parking structures, and demolition of older structures if demand declines.
