Embodiment Construction

[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0022] Four roads, East Road 21, South Road 23, West Road 22, and North Road 24, are selected at the intersection to form a cross intersection. Corresponding areas are set for each of the four roads, and the control method of changing left is applied.

[0023] On the outside of the exit section 27 of South Road 23 and the inside of the right-turn special exit lane 13, the designated area is the exit waiting area 4.

[0024] On the outside of the zebra crossing 14 of Sou...

Abstract

The invention discloses a multi-fork intersection structure and a lower-road entry method. The lower-road entry method comprises arrangement of an intersection and a region of each road, and a signal-control method for the intersection. For the intersection, four primary roads are selected as a crossroad and adopt a turn-left control method; a south road is provided with an entry waiting region and the like; a secondary road adopts a lower-road entry design and the signal-control method, so that the secondary road can be integrated into the turn-left control method of the crossroad; the secondary road can be directly connected with each primary rod. With adoption of the multi-fork intersection structure and the lower-road entry method provided by the invention, the number of phases of the intersection can be reduced, to improve the efficiency of a multi-fork intersection, reduce the delay, prevent vehicles from indirect left turning, and improve the traffic capacity.

Description

technical field [0001] The invention relates to the technical field of traffic roads, and relates to the structure of a multi-fork intersection and a signal control method for merging into a lower road. Background technique [0002] Multi-fork intersections refer to five-fork, six-fork and above intersections, which are often located in prosperous urban areas, where the traffic pressure is extremely high. However, the current signal control of multi-fork intersections generally has many phase cycles, very long cycles, and the ability to pass. The problems of low traffic and large delays often lead to traffic jams and become traffic black spots. The control method of turning left at intersections is suitable for intersections, with large traffic capacity and low delay, which can greatly improve intersections. Contents of the invention [0003] The present invention combines the structure and phase control of the left-changing control method with multi-fork intersections, s...
