Problems solved by technology

In addition, traffic standards vary from place to place. For example, in red light mode, right turns are allowed on some sections of the road, while right turns are not allowed on some sections of the road, which makes it difficult for drivers to make judgments and leads to frequent traffic violations.

Embodiment 1

[0076] From Figure 1 ~ Figure 2 It can be seen that the present invention includes a lamp holder and a bracket for supporting the lamp holder, and also includes traffic signal lights, which are arranged in the waiting area, waiting area, and pedestrian waiting area of ​​the sidewalk in front of each lane at the intersection;

[0077] The traffic lights include four signal indicator groups, which are indicated by red and green signals, which are respectively:

[0078] a. Straight-going indicator light group 2: composed of a straight-going signal light 2a and a waiting signal light 2b arranged longitudinally on the lamp holder;

[0079] b. Left turn indicator light group 1: composed of left turn signal light 1a and left turn waiting signal light 1b arranged longitudinally on the lamp holder;

[0080] c. Right turn indicator light group 3: composed of a right turn signal light 3a and a right turn waiting signal light 3b arranged longitudinally on the lamp holder;

[0081] d. S...

Embodiment 2

[0122] In this embodiment, a medium-sized intersection with medium traffic flow is taken as an example to illustrate the signal indication method: a right-turn waiting area and a pedestrian waiting area may not be set at a medium-sized intersection;

[0123] 1. Signal management for north-south vehicles going straight (see Figure 5 ):

[0124] Vehicles in the north-south direction go straight, the left-turn signal light 1a of the left-turn indicator group 1 in this direction of travel is a red signal, and the left-turn waiting signal light 1b is a green signal, and the left-turning vehicle enters the left-turn waiting area A-5 from the turning lane A and waits;

[0125] The straight-going signal light 2a of the straight-going indicator light group 2 and the signal light 2b to enter are both green signals, and straight-going vehicles pass through;

[0126] The right-turn signal lamp 3a and the right-turn waiting signal lamp 3b of the right-turn indicator group 3 are all red s...

Embodiment 3

[0137] In this embodiment, a small intersection with a small traffic volume is used as an example to illustrate the signal indication method. Due to the small traffic volume and pedestrian flow, there is no right-turn waiting area and pedestrian waiting area at the small intersection. Refer to Table 3 for signal changes;

[0138]

[0139] The difference between this embodiment and Embodiment 2 is that all signal lamps (right-turn signal lamps, right-turn signal lamps) of the right-turn indicator group 3 at each intersection are green signals when the vehicle is going straight, and right-turn vehicles pass normally, see Figure 7 .

[0140] Other control signals of the signal light in this embodiment are the same as those in Embodiment 2.

Abstract

The invention relates to the technical field of traffic management, in particular to a traffic signal system and a vehicle traffic management method at road intersections. Most of the existing traffic lights are pass / stop instructions, and the vehicles waiting for release are located in the intersection. After the release, the first vehicle has a long distance from starting to completely passing the intersection, and the passing efficiency is reduced. The technical scheme of the present invention includes straight-going, left-turn, right-turn, sidewalk indicator light groups, and the area to enter, the area to turn, and the pedestrian waiting area on the sidewalk that are arranged in front of each lane at the intersection; each light group includes two vertically arranged Only signal lights, through the red and green signal instructions, control vehicles and pedestrians to enter the waiting area, waiting area, and pedestrian waiting area first, so as to shorten the distance from the starting position of vehicles or pedestrians to completely passing the intersection, reduce the passing time, and fully Reasonably use the intersection space, improve the efficiency of multi-lane intersections, and alleviate traffic congestion.

Description

technical field [0001] The invention relates to the technical field of traffic management, in particular to a traffic signal system and a vehicle traffic management method at road intersections. Background technique [0002] With the continuous development of cities, the number of cars is increasing year by year, and traffic congestion has become an urgent problem to be solved. Most of the existing traffic lights are pass / stop lights that change through the red and green colors, and the management method is relatively simple. Due to the large area occupied by multi-lane intersections, the passing efficiency of vehicles is reduced. The specific performance is: after the green light is released, the first vehicle waiting to pass is located in the intersection, and the distance from starting to completely passing the intersection is long. Most of the time when entering the intersection is idle, resulting in a waste of road resources. Especially during the rush hour of traffic...
