<p>An adaptive traffic control method and device, the method comprising: acquiring a first-type traffic status parameter corresponding to the traffic status of the first straight-ahead phase in the green wave direction of a current intersection (11); acquiring a second-type traffic status parameter corresponding to the traffic status of the first straight-ahead phase in the green wave direction of an upstream intersection (12); determining the first green light turn-on time of the first straight-ahead phase of the current intersection according to the first-type traffic status parameter and the second-type traffic status parameter (13); determining the first green light duration corresponding to the first straight-ahead phase of the current intersection according to the first-type traffic status parameter and the second-type traffic status parameter (14); and turning on the green light at the first straight phase of the current intersection at the first green light turn-on time, and controlling the green light duration to be the first green light duration (15). The method adjusts the green light turn-on time and the duration of a signal light, enabling as many vehicles as possible to pass through an intersection with multiple signal lights in the green wave band without stopping.</p>
