Example Embodiment

[0034] Example 1: In a three-way intersection, taking a southbound road as an example, a left-loop control method of the intersection structure at an intersection:

[0035] a. Such as figure 2 As shown, the left-turning vehicle of the southbound entrance section 3 stops in the first zone 1. 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. Such as image 3 As shown, vehicles in the first zone 1 of the south entrance section 3 drive to the second zone 2 of the south road in a manner of simultaneously changing to the left or changing to the left with a delay;

[0037] c. such as Figure 4 As shown, vehicles in the second zone 2 of the South Road turn left into the ring road 5, turn left directly and drive out, or drive around the central island 15. If the simultaneous left-turning method is adopted, after the simultaneous left-turning is completed, the ring road exit light 10 of the sout...

Example Embodiment

[0040] Embodiment 2: In an intersection, a left-loop control method for the intersection structure of an intersection: such as Image 6 As shown, according to the needs of the actual situation, a zebra crossing 20 is set at the intersection, and a second zone light 17 is set in the second zone 2. The second zone light 17 includes a pedestrian indicator light and a driving ring indicator light. When the ring road exit light 10 turns red, the entering ring road indicator turns red, the pedestrian indicator turns green, and pedestrians can pass through the intersection; after the vehicle reaches the second zone 2, it needs to wait for the ring road indicator to turn 10 Only after the green can drive into Ring Road 5. More preferably, a right-turning lane 18 and a right-turning exit lane 19 can be added to the intersection to realize a right turn.

Example Embodiment

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

[0042] Expansion plan: At some intersections, you can take a partial phase left loop method, such as Picture 8 , There is a dotted center island 25 in the center of the intersection; Picture 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 Picture 10 , 11 As shown, when the north-south straight traffic lights turn to red lights, the north-south left-turning vehicles, east-west left-turning, and straight-going vehicles pass through the intersection using the left-round control method.

[0043] Furthermore, when adopting the partial phase left loop method, if the number of lanes on the east-west road is small, such as Picture 12 As shown, the right-turn lane may not be provided, an...

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...
