Abstract
The invention discloses an intersection optimizing the brightening of a green light for both direct movement and left turning, comprising an intersection and multiple lane signal indicator boards, wherein the multiple lane signal indicator boards are correspondingly arranged on each lane entering the intersection; and each lane signal indicator board is located 30m to 60m away from the intersection. The signals at the intersection are switched by five phase positions in a cycling manner based on the lane changing function of the lane signal indicator board which controls each lane. The time of entering the lane and spatial resources at the intersection are combined. By reasonably allocating the turning flow at the intersection and spatial and time resources at signal timing, the following unbalanced condition can be effectively solved: in the prior intersection, traffic waiting for turning left queue up too long as the traffic turning left are unbalanced at the left turning lane of the intersection.
