Transport for London is trialling e-paper bus stops that can display real-time travel information.
Fitted with solar-powered panels, they show how long passengers have to wait for the next buses, as well as route maps and timetables.
Four bus stops have been fitted with the tech so far. Chris Foxx quizzed TfL's head of technology Simon Reed about the innovation.
