specific Embodiment approach 1

[0011] Specific implementation mode one: as Figure 1~5 As shown, a kind of road intersection traffic control method that can improve vehicle traffic capacity described in this embodiment is:

[0012] A waiting area 1 is added at each intersection of the intersection, and the waiting area 1 is located at the intersection of the left-turn lane 8 and the straight lane 7, and each waiting area 1 is correspondingly provided with a group of waiting areas Signal lamp 2, the signal lamp 2 in the waiting area respectively indicates that the left-turning vehicle 12 or the straight vehicle 11 enters the waiting area 1, so that the motor vehicles entering the waiting area 1 are all left-turning vehicles 12 or all straight vehicles 11, After the vehicle enters the waiting area 1 in an orderly manner according to the signal lights 2 of the waiting area, it travels according to the instructions of the corresponding central signal lights 3 .

specific Embodiment approach 2

[0013] Specific implementation mode two: as Figure 2-5 As shown, the specific process of the control method described in this embodiment is:

[0014] Now set:

[0015] The green light sequence of the central signal light 3 is:

[0016] Go straight from east to west → turn left from north to south → turn left from east to west → go straight from north to south → go straight from east to west;

[0017] The green light sequence of signal light 2 in the waiting area is:

[0018] Turn left from north to south → turn left from east to west → go straight from north to south → go straight from east to west → turn left from north to south;

[0019] The above four phases constitute a cycle, which will be explained in phases below:

[0020] 1) When the east-west straight signal of the center signal light 3 is green, straight vehicles in the east-west waiting area can enter and pass through the traffic intersection at the same time. At the same time, the left-turn signal green light ...

specific Embodiment approach 3

[0027] Specific implementation mode three: as Figure 1~5 As shown, the waiting area 1 in this embodiment is a rectangular area divided by the original stop line 9 and the newly added pre-stop line 10 on the straight lane 7 and the left-turn lane 8; the length of the waiting area 1 L can be determined according to the actual situation of the intersection and the length of the signal time. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention provides a crossroad traffic control method capable of enhancing the vehicle traffic capacity, and belongs to the technical field of urban traffic control. In order to solve the problem of low vehicle traffic capacity of the conventional traffic intersection control method, the crossroad traffic control method capable of enhancing the vehicle traffic capacity adopts a technical scheme that: a waiting area is added at each intersection of the crossroad, and the waiting areas are positioned at the positions of a left turn lane and a forward lane, wherein each waiting area corresponds a group of waiting area signal lamps; the waiting area signal lamps respectively instruct left turn vehicles or forward vehicles to enter the waiting areas; the motor vehicles entering the waiting areas are the left turn vehicles or forward vehicles; and the motor vehicles orderly enter the waiting areas according to the waiting area signal lamps and run according to the instructions of the corresponding centre signal lamps. The crossroad traffic control method is applicable for traffic management and control of flat crossroads of middle and large cities.

Description

technical field [0001] The invention relates to a traffic control method at a road intersection, belonging to the technical field of urban traffic control. Background technique [0002] At present, along with the growth of urban population, the increase of vehicles, and limited road resources, traffic congestion in cities at home and abroad is becoming more and more serious, especially at some intersections (mainly referring to level crossings) traffic congestion is extremely serious. Urban traffic problem has become a bottleneck of urban development. [0003] Increasing road resources or improving existing road conditions (existing road widening, full interchanges, etc.) is the most fundamental way to solve or alleviate traffic pressure. However, under the current condition of limited urban road resources, improving the traffic management at intersections is a small investment, quick effect, and practical method, which has an immediate effect on alleviating urban traffic p...
