2 2-Phase Traffic Signal Controlled Diamond Interchange

摘要

The present invention relates to a two-state signal control diamond three-dimensional intersection. In general, the main roads of two roads intersecting at one point are either elevated or underground, so that the straight traffic on the two roads can pass freely without mutual interference, and the four lamps are allowed to accommodate traffic entering and entering each other by turning left and right from these two roads. The three-dimensional crossroads that form a diamond shape by intersecting planes with secondary roads on both sides of the road and control these two crossroads with three-way traffic signals are called diamond crossroads. However, in the conventional diamond three-dimensional intersection, the plane intersection is controlled by three manifestation signals, so the average efficiency of the plane intersection is only one third and the length of the red signal is long, and thus the queue is long. The present invention controls the two-turn signal by prohibiting the left turn at the above two plane intersections, and this left turn traffic is guided by the curved lamps separately introduced on both sides of the negative road in the diamond and meets the third road. In addition, this also suggests a two-state signal-controlled diamond three-way intersection that processes all traffic as two-state signals by controlling them with two-state signals and interlocking signals from these three plane intersections. This reduces the traffic congestion by increasing the average efficiency from 1/3 to 1/2 by 50% and reducing the red signal length by half compared to the conventional diamond three-way intersection control.
