Intersection left-turn vehicle continuous passing method and system based on Internet of Things

The invention provides an intersection left-turn vehicle continuous passing method and system based on the Internet of Things, and the method comprises the steps: setting a control region, a first control section, a second control section and a third control section at a road intersection, and obtaining the speed and position information of a vehicle in real time through the Internet of Things; the expected regulation and control speed and the expected regulation and control time headway of the left-turn vehicles are determined through calculation, so that the time headway and the driving speed of the left-turn vehicles are adjusted in advance before the left-turn vehicles enter the intersection, and the left-turn vehicles are subjected to continuous passage regulation and control and pass through the intersection in a formation staggered manner. The original road of the intersection does not need to be transformed, and a left-turn special lane does not need to be additionally arranged; traffic signal lamps a
