Embodiment 1

[0036] The embodiment is basically as attached figure 1 shown, including:

[0037] The parameter acquisition unit is used to collect the traffic state parameters of each lane and send the traffic state parameters. Each lane includes a target tidal lane, a lane with the same current traffic direction as the target tidal lane, and a lane opposite to the current traffic direction of the target tidal lane;

[0038] A video capture unit is used to collect the traffic video of each lane and send the traffic video of each lane;

[0039] The central processing unit is used for judging whether the target tidal lane satisfies the preset conversion condition of the traffic direction according to the traffic state parameters of each lane;

[0040] If the target tidal lane satisfies the preset conversion condition of the traffic direction: sending a trigger acquisition signal to the video capture unit, and receiving the traffic video of each lane collected by the video capture unit;

Embodiment 2

[0056] The only difference from Example 1 is that

[0057] The central processing unit also uses an image recognition algorithm to recognize the license plate number based on the traffic video of each lane, and counts the proportion of vehicles from other places based on the Chinese characters and initials of the license plate number; at the same time, compares the license plate number with the pre-stored license plate number in the database, Count the proportion of regular vehicles; and judge whether the proportion of non-local vehicles is ≤ the first threshold and whether the proportion of regular vehicles is ≥ the second threshold. If the proportion of non-local vehicles is ≤ the first threshold and the proportion of frequent vehicles is ≥ the second threshold, Only then sends the execution conversion signal to the conversion execution unit.

[0058] In addition, the central processing unit is also used to identify the vehicle queue length and weather conditions according t...

Embodiment 3

[0060] The only difference from Embodiment 2 is that when the following two conditions are met at the same time: (1) the target tidal lane meets the preset switching conditions for the direction of travel, (2) the flow overflow value ≥ the first flow threshold and the flow overflow value ≤ the second flow threshold; it is also judged whether the target tidal lane may collapse.

[0061] For such a special situation: the target tidal lane passes through an overpass, that is, a section of the target tidal lane is built on the overpass, and the ordinary lane is directly below the overpass, and the target tidal lane and the ordinary lane are perpendicular to each other. When the vehicle passes the overpass, it will cause the vibration of the subgrade of the target tidal lane. If at the same time there is a truck with a heavy load passing by on the ordinary lane, such as a coal truck with a capacity of about 100 tons, the truck will cause vibration of the foundation, and this vibrat...

Abstract

The invention relates to the technical field of traffic, in particular to a reversible lane traffic control system based on big data. The system comprises a parameter collection unit which is used for collecting the traffic state parameters of lanes; a video shooting unit which is used for collecting traffic videos of all the lanes; a central processing unit which is used for judging whether a target reversible lane meets a preset traffic direction conversion condition or not according to the traffic state parameters of the lanes, judging the size relation of a flow overflow value, a first flow threshold value and a second flow threshold value, and if the flow overflow value is larger than or equal to the first flow threshold value and smaller than or equal to the second flow threshold value, sending a conversion execution signal to a conversion execution unit; and the conversion execution unit which is used for receiving the conversion execution signal, controlling a lane signal lamp corresponding to the target reversible lane and converting the indication direction from the current direction to the opposite direction. The technical problem that in the prior art, traffic flow bottlenecks are likely to be triggered in other surrounding related road sections, and therefore new traffic congestion points are caused is solved.

Description

technical field [0001] The invention relates to the field of traffic technology, in particular to a big data-based tidal lane traffic control system. Background technique [0002] With the acceleration of urbanization, more and more people enter the city to work and live, resulting in more and more people gathered in the city, and people's work and life are also more concentrated. Most people’s daily activity trajectory is that they go to work in the central city from the suburbs in the morning, and return to the suburbs from the central city in the evening to go home. As a result, there are a large number of people who “enter the city in the morning and leave the city at night”, resulting in obvious tides in urban road traffic. This phenomenon makes the utilization of road resources uneven during morning peak and evening peak, and traffic congestion is serious. [0003] In this regard, Chinese patent CN111369789A discloses a control method of a tidal lane signal light, inc...
