Abstract

An intersection road bridge includes a pedestrian underpass, a traffic lane, and a traffic steel bridge. The pedestrian underpass is I-shaped in structure and is transversally arranged at the middle of an intersection. The traffic lane includes more than bi-directional four lanes, wherein the lane pavement being closed to a starting junction of vehicles is marked with traffic guiding arrows and six traffic lights are arranged over the position being closed to a drive-to junction. The traffic steel bridge is arranged in the middle of the intersection. Straight-driving vehicles at the two ends of the traffic steel bridge is free of control of the traffic lights and the right-turning vehicles at the four directions are free of control of the traffic lights too. The six traffic lights are divided into two groups and send control signals contrarily and cyclically. The vehicles on the traffic lane are divided into two groups in a manner of two vehicles turns left while one vehicle runs straightly, so that the vehicles passes the intersection orderly in turns according to signals with the groups as units, wherein the left-turning vehicles are driven out from the road intersection in a 90-degree turning path. According to the invention, the intersection road bridge achieves people and vehicles to be separated from each other by means of the pedestrian underpass and the traffic steel bridge, so that the cyclic period of the traffic signal is reduced from four times to two times and the traffic capacity of the intersection road bridge is increased by more than 75%.
