The invention discloses an intelligent transportation traffic lamp control method which includes judging whether vehicle flow of a first two-way road is zero, on yes judgment, entering the next detection switching period, wherein a traffic lamp of the first two-way road is in the state that a red lamp is normally on; judging whether vehicle flow of a second two-way road intersecting with the first two-way road is zero, on yes judgment, entering the next detection switching period, wherein the traffic lamp of the second two-way road is in the state that a red lamp is normally on; setting passing time of the first two-way road signal lamp to be a product of the vehicle flow of the second two-way road and single vehicle passing time and entering the next detection switching period. By means of the method, the problem of traffic lamp switching conducted when the vehicle flows of different directions are different is solved, waiting time in each direction is reduced, and the passing efficiency is improved.
