It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Four roads, namely an east road 21, a south road 23, a west road 22 and a north road 24, are selected to form the intersection, and the four roads are respectively provided with corresponding areas and are subjected to a left-changing control method.

The outside of the exit section 27 of the south road 23 and the inside of the exit lane 13 for right turn define an area as the merging waiting area 4.

Outside the zebra crossing 14 of the south road 23, a merging lane 8 is defined from the east-left second zone 2 to the exit section 19 of the south road 23, and a corresponding merging lane guide line 9 is drawn on the road surface.

A convergent-in waiting area 16 is defined behind a convergent-out lane 8 of the south road 23 close to the center 12 of the intersection; a merging lane 10 is defined between the secondary road waiting area 15 and the merging waiting area 16, and a corresponding merging lane guide line 11 is drawn; behind the merging candidate 16 and the merging target 10, the left-turning lane 6, the right-straight waiting area 3, and the left first area 1 of the south road 23 are provided.

The sub road 25 is provided with at least 1 left-turn exclusive entrance lane 17 for vehicles traveling to the west road.

After the vehicle in the first left zone 1 on the south road 23 enters the second left zone 20 and departs from the second left zone 20, the vehicle in the left-turn exclusive entrance lane 17 on the secondary road 25 is allowed to exit, following the second left zone 20, to the west road 22. As shown in fig. 3.

During the passing phase of the south road 23 and the north road 24, the north road 24 drives the vehicle to the secondary road 25 and drives into the merge-exit waiting area 4 to stop. As shown in fig. 4.

During the phases of passage of the east 21 and west 22 roads, the vehicles of the secondary waiting area 15 are allowed to exit, wherein the vehicles to the north 24 and east 21 roads are driven into the merge waiting area 16 for parking, while the vehicles to the south 23 of the right-turn exit lane 13 are prohibited from being driven out, and the vehicles to the secondary 2 to the east-left area pass through the merge lane 8 to the merge waiting area 4 or the south 23 exit segment 19, and are driven to the secondary 25 together with the vehicles to the merge waiting area 4. As shown in fig. 5.

At the end of the passing phase of the east road 21 and the west road 22, the merge waiting area 16 passes to the east road 21. As shown in fig. 6.

4 roads with large traffic flow and similar crossroads at the multi-fork intersection are selected as main roads, each east road is provided with a first-left area and a second-left area, the lights are arranged, and a left-changing control method is applied, so that the passing capacity of the intersection can be greatly improved, and delay is reduced.

The area of the secondary road entrance can be used as the south second-left area 20, and the dotted line and the stop line of the secondary road entrance are used as the boundary marks of the left second area, so that the land area is saved. The secondary exit lane 18 may be set to 2 lanes to expedite vehicle egress.

The remittance waiting area 4 is defined so that the vehicles driving on the north road 24 and going to the secondary road 25 can stop in the remittance waiting area 4 for waiting. The merging lane 8 is defined so that vehicles in the second east-leftwards area 2 which want to go on the secondary road 25 can pass through the entrance section of the south road through the merging lane 8, drive into the merging-waiting area 4 or the exit section 19 of the south road 23, and then drive on the secondary road 25. The merge-in lane 10 is defined so that vehicles in the sub-road waiting area 15 that intend to go to the north road 24 and the east road 21 can enter the merge-in waiting area 16 to stop.

As shown in fig. 6, the vehicle in the secondary waiting area 15 that intends to enter the merge-in waiting area 16 for waiting on the north road 24 and the east road 21 is prohibited from exiting the right-turn exit lane 13 on the south road 23, and the vehicle in the merge-out waiting area 4 and the east-left second area 2 that passes through the merge-out lane 8 and travels on the secondary road 25 turns right on the forward road. In the next phase of the south road 23 and the north road 24, the vehicle entering the waiting area 16 can drive to the north road 24.

By applying the multi-intersection structure and the convergence method, intersections such as five-intersection intersections and six-intersection intersections can be simplified into four-intersection intersections, two-phase control is applied, the secondary roads can be communicated with other roads, troubles such as turning around due to the fact that the secondary roads need to be led far in and out are avoided, streets can be bypassed, and pressure of downstream roads is reduced. Therefore, an advanced left-changing control method is applied, the phase of the intersection is reduced into two phases, the traffic capacity is greatly improved, the delay is reduced, and the method has great application value.
