Inspired by traffic jams caused by car accidents, we designed ’Stream-UAV’, a UAV service system aiming to keep the traffic system operating efficiently even if an accident occurs on the city road.
When a car accident happened, drivers’ unawareness of car accidents will make traffic jams worse, the Stream-UAV can project traffic signs onto the road away from the accident, to cover the original signs, so the drivers are reminded to make a turn or change lane in advance to avoid getting into a traffic jam.
