Embodiment 1

[0034] Embodiment 1: In a three-fork intersection, taking a southbound road as an example, a left-circle control method for an intersection structure at an intersection:

[0035] a. If figure 2 As shown, the left-turning vehicle of the southbound entrance section 3 is parked in the first area 1, and when the southbound ring road exit light 10 turns into a red light, the vehicle is prohibited from entering the southbound exit lane 16;

[0036] b. If image 3 As shown in , vehicles in the first zone 1 of the southbound entrance section 3 drive to the second zone 2 of the south road by turning left at the same time or with a delay in turning left;

[0037] c. If Figure 4 As shown, vehicles in the second zone 2 of South Road turn left into the ring road 5, turn left directly and drive out, or drive around the center island 15. If adopting the way of turning left simultaneously, then after turning left simultaneously, the ring road exit light 10 of the southbound road turns in...

Embodiment 2

[0040] Embodiment two: in the crossroads, the left circle control method of the intersection structure of a kind of intersection: as Figure 6 As shown, according to the needs of the actual situation, a zebra crossing 20 is set at an intersection, and a second district lamp 17 is provided in the second district 2, and the second district lamp 17 includes a pedestrian indicator light and an indicator light for entering a circular road. After the ring road exit light 10 turns to red light, enter the ring road indicator light and turn red, the pedestrian indicator light turns green, and pedestrians can pass through the intersection; after the vehicle travels to the second district 2, it is necessary to wait for the ring road indicator light to turn 10 times. You can enter Ring Road 5 after turning green. More preferably, a right-turn lane 18 and a right-turn exit lane 19 can be added at the intersection to realize a right turn.

Embodiment 3

[0041] Embodiment three: as Figure 7 As shown, in five-fork, six-fork and above intersections, a left circular control method of the intersection structure of the intersection can also be applied.

[0042] Expansion scheme: In some intersections, the method of partial phase left circular movement can be adopted, such as Figure 8 , there is a dotted center island 25 in the center of the intersection; for example Figure 9 As shown, the north-south straight phase: north-south left-turning vehicles, east-west left-turning and straight-going vehicles stop in the first zone 1 of each road. Such as Figure 10 , 11 As shown, when the north-south straight traffic lights turn to red lights, north-south left-turn vehicles, east-west left-turn vehicles, and straight-going vehicles adopt the left circular traffic control method to pass through the intersection.

[0043] Furthermore, when using the method of partial phase left circular driving, if the number of east-west lanes is small...

Abstract

The invention discloses an intersection structure of an intersection and a left circuit control method of the intersection structure. The intersection is provided with a center island (15) and a circuit (5). An entrance section (3) is provided with a first zone (1). An exit section (4) is provided with a second zone (2). When a circuit exit lamp (10) is turned to be red, vehicles are forbidden to drive out of an exit lane (16), and the vehicles parked in the first zone (1) enter the second zone (2) in the manner of simultaneously turning leftwards or turning leftwards in a time delay manner, and afterwards, the vehicles of the second zone (2) enter the circuit (5) to turn leftwards or circuit. When the circuit exit lamp (10) turns to be green, the vehicles can drive towards the exit lane (16) and drive out of the intersection. By means of the scheme, the purpose of intersection roads is definitely planned, the roads are used more flexibly, the traffic capability of dealing with the intersection is improved, the vehicle passing cycle is shortened, the delay time is shortened, and therefore the effect of dredging the blocked intersection is achieved.

Description

technical field [0001] The invention relates to the technical field of traffic roads, in particular to an intersection structure of an intersection and a left circular control method thereof. Background technique [0002] With the rapid development of the economy, the number of vehicles in the city is increasing day by day. How to maintain orderly urban traffic and improve road traffic capacity has always been a difficult problem. Intersections can be seen everywhere in the city. The most difficult thing to deal with at the intersection is the left-turning vehicle. The left-turning vehicle is the most important factor causing the low traffic capacity and long delay time of the intersection. In ordinary roundabout intersections, vehicles circle counterclockwise, and left-turning vehicles generally need to circle more than half a circle. The proportion is not large, but it takes a long cycle time; the above situations are the main reasons for the low traffic capacity and long...
