Disclosed in the invention is a traffic signal lamp indication system comprising a PLC control part, a piezoelectric part, a sensor part and a signal lamp indicator part. The piezoelectric system is installed at a right side passageway of a road. The sensor part is formed by a pressure sensor and is installed at the piezoelectric ceramic top of the piezoelectric part. The signal lamp indicator part is formed by a vehicle running signal lamp, a digital signal lamp, and a pedestrian signal lamp; and the vehicle running signal lamp can display two kinds of colors of the red color and the green color, wherein the red color represents information of no entry and the green color represents information of going. The piezoelectric part, the sensor part, and the signal lamp indicator part are connected to the PLC control par by cables. According to the invention, on the basis of the principle that when first comes at an intersection, first passes through the intersection, vehicles can pass through the intersection rapidly with high efficiency. Meanwhile, the piezoelectric part is installed at the intersection and the pressure of the vehicle is changed into electric energy, so that the energy is effectively utilized. The system has the broad application prospects.
