Imagining the Driverless City

Costa Samaras, an assistant professor of civil and environmental engineering at Carnegie Mellon University in Pittsburgh, envisions autonomous vehicle zones in dense urban cores that allow drop-offs between 7 a.m. and 10 a.m., and then convert to pedestrian-only thoroughfares until evening. Such zones would not necessarily need bollards to block traffic, since the rules could be transmitted to cars electronically, he says.
