The invention relates to a digital traffic dynamic adjustment control system and method for a tramcar level crossing, and belongs to the technical field of ground traffic control, and the system comprises an induction trigger module which is disposed at the upstream of the crossing, and is used for obtaining and uploading the dynamic information of the tramcar, and outputting a trigger signal; a traffic flow detection module; the signal control module is used for outputting a signal lamp adjusting instruction and/or an electric vehicle speed control instruction; a vehicle-mounted controller; the induction trigger module comprises a thunder-vision all-in-one machine and a time processor, and the time processor presets an arrival duration threshold value and calculates the predicted duration of the electric vehicle arriving at the intersection according to the dynamic information of the electric vehicle; the time processor compares the predicted time length with the arrival time length threshold value, and when the predicted time length reaches the arrival time length threshold value, a trigger signal is output; the arrival time threshold is greater than a signal lamp period of a first intersection downstream the induction trigger module. The method has the effect of reducing the sudden change of the intersection signal lamp caused by the priority control of the electric vehicle.
