Embodiment 11

[0073] A kind of entrance and exit, the entrance and exit are road sections close to the intersection area, divided into exit and entrance, and the entrance has a left turn waiting area 1 and a straight line waiting area. There is an exit lane 13 at the exit, and the middle of the left-turn waiting area and the exit lane is the central isolation belt, such as figure 2 shown.

[0074] The central isolation zone between the left-turn waiting area 1 and the exit lane 13 allows vehicles to cross, that is, the isolation zone cannot be obstacles such as flowers and trees, curbs, but draws paint lines, lays rubber plates, etc. to represent the isolation zone. On the outside of the exit lane of this entrance and exit, there is a reverse lane. The driving direction of the reverse lane is opposite to that of the exit lane. An arrow in the same direction as the left-turn waiting area is drawn on the reverse lane. The isolation zone 16 between the exit lane 13 and the reverse lane 2 all...

Embodiment 12

[0080] Others are the same as the previous embodiment, the difference is:

[0081] The lane number of the exit lane is 2. Above the reverse lane, from front to back, set a lane-changing light every 20 meters, a total of 3 lane-changing lights. The most front lane change light is the first lane change light, and the horizontal distance from the first lane change light to the extension line is 11 meters. The installation position of the first lane change light is 25 meters ahead of the intersection of the front end of the left-turn waiting area and the central isolation belt. The reverse lane is in front of the left-turn waiting area, the front end of the reverse lane is 20 meters ahead of the front end of the left-turn waiting area, and the back end of the reverse lane is 20 meters ahead of the rear end of the left-turn waiting area.

[0082]The left-turning vehicle enters the left-turning lane without stopping after reaching the reverse lane. In each cycle, the green durati...

Embodiment 13

[0086] Others are the same as Example 1.1, the difference is:

[0087] The reverse lane is 1 lane, but there are 2 lanes at the exit of the reverse lane, and the left-turn lane is also equipped with 2 lanes, such as Figure 5 The reverse lane of Road C and its adjoining left-turn lane. The exit of this kind of reverse lane makes the transition from one lane to two, which can speed up the driving speed of vehicles in the reverse lane, turn into free flow faster, and improve the passing capacity of the reverse lane. 2-lane left-turn waiting area and reverse lane, the general left-turn traffic capacity can reach 800-1300puh / h, which can meet the needs of two two-way 6-10 lane road intersections.

[0088] An intersection is composed of 3 or more entrances and exits, but not all entrances and exits must use batch lane change entrances and exits, and only some of the entrances and exits may be batch lane change entrances and exits.

Abstract

The invention provides a structure of a batch lane changing entrance and exit and application thereof. A retrograde lane is arranged outside exit lanes of an exit and is in butt joint with a left turning lane of the next intersection, lane changing signal lamps are arranged in left front of a left turning waiting area, and under the guidance of green bright bands of the lane changing signal lamps,vehicles on the left turning waiting area independently drive to the left front and then drive into the retrograde lane to clear the exit lanes, so that the blockage of the exit lanes is reduced andavoided as much as possible. The method is very little in blockage of the exit lanes throughout the cycle, and an intersection using such an intersection can use two-phase control; each intersection of a roundabout adopts the batch lane changing entrance and exit, so that the roundabout becomes a left roundabout, and the vehicles enter the roundabout through turning left; and by applying the batchlane changing entrance and exit, the passing capability of city intersections is greatly enhanced, and the delay is reduced.

Description

technical field [0001] The invention relates to the traffic field, and relates to an intersection structure, a signal lamp, and phase control, in particular to a structure of an entrance and exit for batch lane changes and its application. Background technique [0002] Most of the current intersections use three-phase control at three-way intersections, four-phase control at intersections, and more complex phases at multi-fork intersections. The left-turning lanes at the intersection are all within the intersection area, intersecting with the through lane, and each left-turning lane is intersecting, thus forming a conflict. The cycle of these intersections is long, each phase lasts 30-50 seconds, and the traffic capacity is low. The main cause of these disadvantages is that there are many conflict points of left-turning vehicles, blocking straight-going vehicles and blocking exit lanes, and a lot of cycle time must be spent to release left-turning vehicles. [0003] Inters...
