Traffic drone+ / Traffic control devices

Traffic drone+ is a concept that can help to give way to the ambulances and direct traffic effectively. Sometimes surrounding noise can easily cover the ambulance wailing. It will cause chaos at the intersections. This new design is set upon the traffic lights of crossroads. When the ambulance is about to pass the crossroad, Traffic drone + will receive the message, fly to the center of crossroad, and launch alarm. It can guide the vehicles on each road to give way to the ambulance correctly. Thus the ambulance can pass the crossroad quickly and safely. In addition, it can do traffic directing effectively and reduce the risks of policemen.
