Embodiment 1

[0028]Embodiment one: a kind of vehicle guidance method of traffic crossing, on the ground leading to each lane of traffic crossing, a column of guiding lights is set, and described guiding lights are positioned at the center of lane, and guiding lights have two colors of red and green, set The length of the lane with guide lights is 500 meters from the intersection; set the speed at the intersection, determine the length of the lane occupied by the red and green guide lights according to the duration of the red and green lights and the speed of the intersection, and change the corresponding position of the guide lights. Display color, control the color segment of the guide light to move to the intersection at the speed of the intersection, so that the color of the guide light at the intersection remains matched with the color of the traffic signal light.

Embodiment 2

[0029] Embodiment 2: A vehicle guidance method at a traffic intersection. Two rows of guide lights are arranged on the ground of each lane leading to the traffic intersection. The guide lights are located on the left and right sides of the lane, and the guide lights have red The length of the lane with guide lights is 800 meters from the intersection; set the speed at the intersection, and determine the length of the lane occupied by the red and green guide lights according to the duration of the red and green lights and the speed of the intersection. By changing the display color of the guide light at the corresponding position, the color segment of the guide light is controlled to move to the intersection at the passing speed of the intersection, so that the color of the guide light at the intersection remains matched with the color of the traffic signal light. A vehicle traffic flow sensing device is installed at the traffic intersection. When the traffic flow at the interse...

Embodiment 3

[0031] Embodiment 3: A vehicle guidance method at a traffic intersection. Two rows of guide lights are arranged on the ground of each lane leading to the traffic intersection. The guide lights are located on the left and right sides of the lane, and the guide lights have red The length of the lane with guide lights is 600 meters from the intersection; set the traffic speed at the intersection, and determine the location of the red and green guide lights according to the duration of the red, green, and yellow lights and the traffic speed at the intersection. Occupying the length of the lane, by changing the display color of the guide light at the corresponding position, the color segment of the guide light is controlled to move to the intersection at the speed of the intersection, so that the color of the guide light at the intersection remains matched with the color of the traffic signal light. A vehicle traffic flow sensing device is installed at the traffic intersection. When...

Abstract

The invention discloses a method for guiding vehicles at a road intersection. The method is characterized in that: at least a row of guiding lamps are arranged on the ground of each lane leading to the road intersection; the guiding lamps have two colors of green and red; the length of the lanes provided with the guiding lamps is at least 200 meters from the intersection; traffic speed at the intersection is set; length of road occupied by the red and green guiding lamps is determined by the lasting time of the red and greed traffic lights and the traffic speed at the intersection; color sections of guiding lamps are controlled to perform movable display towards the intersection at the traffic speed at the intersection by changing displaying colors of guiding lamps at corresponding positions, so that the colors of the guiding lamps at the intersection are matched with the colors of the traffic lights. The method automatically divides vehicles into groups; each group of vehicles arrives at the intersection just when the traffic light is green; therefore, vehicles run through the intersection without waiting; and the method improves traffic capability of vehicles within the same green light period, reduces exhaust emission and saves gasoline.

Description

technical field [0001] The invention relates to a method for road traffic management, in particular to a method for guiding vehicles at traffic intersections. Background technique [0002] In the prior art, at traffic intersections, the passage of vehicles is usually guided by setting traffic lights. When the traffic lights are green, the corresponding vehicles can pass. When the traffic lights are red, the corresponding vehicles are prohibited from passing; At the intersection of lanes, left-turning, straight-going, and right-turning lanes are respectively set up, and there are also straight-going and right-turning lanes that share the same lane. On these lanes, ground traffic guidance signs are set to make vehicles drive in separate lanes according to the signs. [0003] However, because the switching time of red light and green light in traffic lights is random for drivers, it is difficult to predict the management state (release or prohibition) when arriving at the next ...
