Wie verändert autonomes Fahren eigentlich das Parken in der Stadt? Schauen wir uns mal ein paar Möglichkeiten an.
Autonomous vehicles could, in principle, transform parking lots. When people park cars, they need space to open the doors and walk away, but driverless cars do not need such space. And parking lots devoted to autonomous vehicles would not require elevators and staircases—the owners could simply be dropped off by the machines at the entrance or some other destination and let the vehicles park themselves. To see how much autonomous vehicles could increase the capacity of parking lots, researchers at the University of Toronto calculated the optimal size of the grids in which driverless cars park themselves. If a grid is too large, it takes longer on average for one of the autonomous vehicles to exit, since the surrounding cars have to spend time relocating as needed. If a grid is too small, it wastes space.
The researchers developed a computer model that simulated the effects of various layouts for autonomous-vehicle parking lots. They found that such lots could accommodate 62 to 87 percent more cars than ones for conventional vehicles. This more efficient use of space could lead to smaller parking lots, and possibly free up urban space. “That land could be allocated to other activities—residential space, perhaps, or maybe green areas for everyone,” says study coauthor Sina Bahrami, a transportation engineer at the University of Toronto.
