Problems solved by technology

[0003] At present, most of the commonly used intersection warning lights adopt the time-limiting method of equal long intervals, that is, regardless of the traffic volume, the vehicle waiting time or passing time is fixedly set. This method cannot adapt to different road conditions, and it is prone to traffic jams or idle waiting situations.

Embodiment 2

[0054] It is preferred to number the traffic flow monitoring cameras as follows: 10, 20, 30, 40, 50, 60, 70, 80; that is, Figure 4 The functions of the 8 traffic monitoring cameras are shown in Table 1 below

[0055] Table 1

[0056]

[0057] It should be noted that the flow monitoring camera of the present invention is identified as number 10 above.

[0058] According to the above numbers, the system workflow in this embodiment is as follows: Figure 5 shown.

[0059] As above, the CPU will send traffic flow detection commands to the traffic flow cameras 1 to 8 every time interval T, and obtain the traffic flow V1, U1; V2, U2; V3, U3; V4 on the current route 1 / 2 / 3 / 4 respectively , U4; here define the traffic flow detected by each traffic monitoring camera at the nT-S moment as V1(n), U1(n), V2(n), U2(n), V3(n), U3(n), V4(n), U4(n); Among them, V1(n) is the traffic flow detected on route 1 flowing into the traffic light method, U1(n) is the traffic flow detected on rou...

Abstract

The invention discloses a warning light for road traffic, which relates to the field of traffic management. The warning light for road traffic includes a warning device. Each of the sides faces a path branch respectively, and each side is provided with two traffic flow monitoring cameras. The square is in the shape of a cavity, and a central processing unit CPU and a storage module are arranged in the cavity. The top of the square is provided with a horizontally placed cross, and the four tops of the cross correspond to the four path branches one by one, and each top of the cross is provided with an indicator light; the CPU and the storage module, four indicator lights And the 8 traffic flow monitoring cameras are connected through the data bus; and the method of intelligently controlling the traffic lights that can intelligently control the traffic limit time based on the traffic flow monitoring camera assistance by the CPU can realize the dynamic adjustment of the traffic limit time to obtain the optimal Traffic flow control.

Description

technical field [0001] The invention relates to the field of traffic management, in particular to a warning light for road traffic. Background technique [0002] From the meaning of the word, the road is the infrastructure for various trackless vehicles and pedestrians. According to its use characteristics, it can be divided into highways, urban roads, rural roads, factory and mine roads, forestry roads, examination roads, competition roads, automobile test roads, and workshop passages. And school roads, etc. In addition, it also refers to the way to achieve a certain goal, the way things develop and change. Transportation refers to the industries engaged in passenger and cargo transportation and language and graphic transmission, including transportation and post and telecommunications. In the national economy China belongs to the tertiary industry. There are five modes of transportation: railways, highways, waterways, aviation, and pipelines. Posts and telecommunications i...
