The present invention relates to a surface street intersection system which is capable of easily controlling straight-through runs, left turns and U-turns of vehicles by a two-phase signal intersection traffic signal consisting only of a straight-through signal and a stop signal. Therefore, a two-phase signal four-way intersection system is provided wherein left-turning vehicles together with right-turning vehicles make a right turn and then make a U-turn on the crossing road to thereby finally result in a left turn of the vehicles, only by a straight-through signal without a left turn signal. In this manner, since the left-turning vehicles make a right turn together with the right-turning vehicles, the inside-lane vehicles can always go straight only to thereby result in smooth traffic flows. Further, the traffic light at the intersection consists only of a straight-through signal and a stop signal, so a traffic signal waiting time of drivers can be greatly reduced to provide significantly increased traffic capacity. |
