[0030] Embodiment 1, an embodiment of a six-way intersection, referring to FIG. 1 , each main road has six lanes in both directions.

[0031] The basic characteristics of the intersection: Because each intersection has 5 pairs of vehicles to travel, for this reason, the number of lane groups with different orientations near the intersection should be expanded to 10 groups. Each group can be one lane or multiple lanes. Take the south intersection as an example to illustrate the main structure:

[0032] A. Except for the right-most right-turn lane [group], the waiting areas of different directional lanes are moved back a certain distance [such as 50 to 200m] from the original upward intersection to form the first waiting area (1). The left field of area (" is all down-going lanes. There are 4 groups of lane groups with different driving directions in area (1). In Figure 1, only 1 lane is taken for each group. From left to right, the order of different directional lanes is: left, Center left, center, center right.

[0033] B. The leftmost side of the motor vehicle road at each intersection is the down lane [referring to the lane that turns right from the left-adjacent intersection]. Set the second set of lanes from the left on the left side of the intersection [called the first directional upward lane from the left (6)] as the first "second transition zone ("second transition zone) for vehicles to turn left and go up or wait to go out. 3)".

[0034] C. Set the right adjacent lane of the first second transition zone (3) as the first third transition zone (4) of the intersection.

[0035] The number of the second transition area (3) and the third transition area (4) are both four. They are arranged alternately from left to right, that is, starting from the down lane (5) entering from a right turn at the left adjacent intersection, the order from left to right is left down and right up, that is, the pattern of one entry and one exit is repeated until all the Go to the up road (7) [in this example: turn right up road] on the right boundary of the intersection.

[0036] D, between the first waiting area and each second transition area, there are 4 upstream channels corresponding to each other;

[0037] There is also a one-to-one correspondence of 4 passages between each third waiting area and the descending lane, but they are descending passages.

[0038] These ascending and descending passages are arranged in an orderly manner to form a cross rectification area and a lane change area that play the role of bidirectionally combing the traffic flow, referred to as the cross rectification area (2). The function of the cross rectification area is to sort out the traffic flow in an orderly manner, so that the upward and downward traffic flows can travel along the orderly and non-conflicting lanes after passing through the cross rectification area.

[0039] 4 upstream channels for the traffic from the first waiting area (1) in the 4 driving directions to "reverse" through the cross rectification area (2), and then enter the respective second transition area (3);

[0040] The 4 downlink channels are used for the downlink traffic from the 4 third waiting areas (4) to go their separate ways after passing through the cross rectification area (2).

[0041] It also features:

[0042] In front of the first waiting area (1), in the cross rectification area and its associated area, including the neutral gear between different lanes, a directional green island (9) is constructed which is conducive to safe driving and prevents traffic conflict. For a multi-way intersection, (9) is "island"; for the intersection described below, it is a double or isolated island. Driving route signs and signal lights can be set up on the green island; on the road surface of the cross rectification area (2), arrows of different colors indicate the driving directions of different directional traffic flows.

[0043] For a multi-way intersection, the second transition zone (3) corresponds to the second waiting zone. Set up a larger second transition area, which can accommodate more left-turning vehicles. The area of the second transition zone (3) should preferably be larger than the first waiting zone (1) to simplify the management of the signal lights.

[0044] It can be seen from Figure 1 that after setting these three areas, the traffic flow at each neighboring intersection can turn left and right at the same time without conflict, and each intersection can also receive the traffic entering the left and right turns at the same time, so the traffic flow increases to 12. share. When the south junction is released, the 6 traffic flows at the other 3 junctions face each other. A total of 12+6=18 groups of traffic flow. This is the benefit, the effect of maximizing traffic flow.

[0045] In this example, in the first round [each round, three intersections], the six-way intersection is controlled by each intersection interval to release in turn, and then another intersection starts to be released in another round. The way of taking turns can be diversified, that is, at the same intersection, including the commute time, the time period is different, and the optimized interval should also change according to the specific situation.

[0046] Compared to the original traffic light system, green lights for 'left' turns and 'go straight' are now incorporated. At the same time, a second signal light system for coordinating and controlling the three zones (1), (3) and (4) is added. The second signal light system mainly includes: an upward signal light (10) is arranged at the exit of the first waiting area (1), and a guard signal light (11) is arranged at the entrance of the first area. At the exit of the third transition zone (4), three zone down signals (8) are arranged. The operation mode of the second signal light will be illustrated in the following embodiments.

[0047] For the operation of traffic flow in different directions, it will be explained at the intersection with few variables.
