Far from the disorderly world of big city streets, Mart Suurkask, the CEO and founder of Bercman Technologies, demonstrates a working prototype of the firm’s “smart pedestrian crosswalk” to a small crowd of onlookers gathered at a trade show booth hosted by the Government of Estonia. The device looks exactly like crosswalk signs throughout Europe — a post supporting a square sign with the universal symbol of a pedestrian crossing a street. What makes it “smart,” as he explains, is an assembly of digital devices stowed inside the sign: high-tech motion detectors aimed in all directions that are programmed to calculate the velocity of vehicles approaching the crosswalk to determine if vehicles are slowing safely when someone is crossing.
