Embodiment 1

[0036] Embodiment one, with reference to figure 1 and figure 2 as well as image 3 as shown,

[0037] The present embodiment takes the two-way road as an example. The so-called two-way means that a crosswalk 33 across the road and a diversion line 32 are provided on one passage, and there are signal lights 10 to regulate the passage of passing vehicles 80 in both directions. Here Usually, signal lights 10 only have straight traffic lights, and there are at most U-turn signal indicators. In this embodiment, the road information transmitting unit 20 is set up near the vehicle stop line 31. The road information transmitting unit 20 and the instruction issuing unit 40 is connected to and receives its data signal. The road information transmitting unit 20 sends out the real-time status of the signal light 10. The information sent is divided into a straight line signal group or a straight line signal group and a U-turn line signal group. This embodiment will be described later. ...

Embodiment 2

[0042] Embodiment two, refer to figure 1 , 2 , as shown in 4,

[0043] This embodiment takes a three-channel road as an example, which is commonly known as a "T-shaped intersection". The setting of the direction information is the same as that described in Embodiment 1. At this type of intersection, usually the signal lights will have straight traffic lights, turn left traffic lights, and turn right Signal lights and U-turn traffic lights, the present embodiment considers setting up the road information transmitting unit 20 near the vehicle stop line, and the road information transmitting unit 20 can also be set at the intersection central position, the road information transmitting unit 20 and the instruction issuing unit 40 Connect and receive its data signal, the road information transmitting unit 20 sends out the real-time status of the signal lamp 10, and the sent information is divided into a straight line group, a left turn signal group, a right turn signal group, and ...

Embodiment 3

[0047] Embodiment three, refer to figure 1 , 2 , as shown in 4,

[0048] This embodiment takes the four-way road as an example, that is, "crossroads". The setting of the direction information is the same as that described in Embodiment 1. At such intersections, the signal lights usually have traffic lights for going straight, traffic lights for turning left and right, and traffic lights for turning around. Then, near this signal light, the present embodiment considers setting up the road information transmitting unit 20 near the vehicle stop line, and the road information transmitting unit 20 can also be set at the intersection central position, and the road information transmitting unit 20 is connected with the instruction issuing unit. 40 is connected to and receives its data signal, and the road information transmitting unit 20 sends out the real-time status of the signal light 10, and the information sent is divided into a straight line group, a left turn signal group, a ...

Abstract

Provided is a road information receiving system, comprising a control and directing unit having road information and traffic light status data, and further comprising a road information transmission unit, a vehicle movement direction determination unit, and a vehicle on-board unit, the vehicle on-board unit comprising an information receiving device, a processor, a vehicle direction positioning device, and an output device. The traffic light status at an intersection is transmitted outward or sent by means of a road information server unit; the information receiving device receives the information; the vehicle direction positioning device determines the number of the intersection where the vehicle is; the processor selects the status of the traffic light of the matching direction from a traffic light status signal according to the number of the intersection, and transmits by means of the output device the status to a driver as reference regarding the intersection. When a large vehicle in front blocks the view, or when a driver has color blindness or color deficiency, the driver can accurately receive image or voice alerts via the output device, so that the vehicle can safely and rapidly go through the intersection or stop in time according to the traffic light status.

Description

technical field [0001] The invention belongs to the field of road traffic safety, in particular to the technical field of receiving and processing road state information. Background technique [0002] When a car passes through a traffic light intersection, it often encounters a large vehicle ahead, such as a bus, an earthwork truck, a large truck, etc., which block the sight of subsequent vehicles and make it impossible for subsequent vehicles to judge the intersection ahead. According to the actual state of the signal lights, it is easy for vehicles following up to run the red light behind the large vehicles. If you wait for the large vehicles to pass first and see the signal lights before passing the intersection, it will inevitably cause congestion at the intersection. In addition, there are bad weather such as heavy fog, heavy rain or It is also easy to run a red light when it is difficult to see the signal lights under strong backlighting conditions. As a result of the...
