Embodiment 1

[0040] An embodiment of the present invention provides a flat-peak self-adaptive traffic flow control method, such as figure 1 As shown, it includes the following steps to be run on the traffic control equipment set at the current light-controlled intersection:

[0041]Step S1: Acquire real-time vehicle information within the first preset range outside the light-controlled intersection. For example: Real-time detection of vehicles through cameras set on the current road to obtain the dynamics or number of vehicles. The preset length range here is calculated according to the green light time of pedestrians passing in the vertical direction of the vehicle traffic direction and the preset vehicle speed of the current road, or, the preset length range is calculated according to the preset vehicle speed and preset time of the current road calculated.

[0042] Step S2: Identify and acquire the fleet information in the vehicle information according to the vehicle information and th...

Embodiment 2

[0075] An embodiment of the present invention provides a flat-peak adaptive traffic control device, such as image 3 As shown, it includes the following modules running on the traffic control equipment set at the current light-controlled intersection:

[0076] The first acquisition module 31 is used to acquire vehicle information in a first preset range outside the light-controlled intersection on the current road in real time;

[0077] The fleet identification module 32 is used to identify and obtain the fleet information in the vehicle information according to the vehicle information and the preset fleet identification strategy; the preset fleet identification strategy includes: starting from the first vehicle, inducing to form the first fleet of predetermined length;

[0078] Fleet judging module 33, for judging whether there is the first motorcade that is about to enter the first preset range outside the light-controlled intersection; When entering the first convoy at the...

Embodiment 3

[0095] An embodiment of the present invention provides a storage medium on which computer instructions are stored. When the instructions are executed by a processor, the steps of the peak-evening adaptive traffic control method in Embodiment 1 are implemented. Also stored on the storage medium are vehicle information and / or pedestrian information, first preset range, fleet information, preset maximum vehicle distance, maximum fleet length, single longest green light time, second preset range, cycle time, preset Set off-peak time, etc. Wherein, the storage medium may be a magnetic disk, an optical disk, a read-only memory (Read-Only Memory, ROM), a random access memory (Random Access Memory, RAM), a flash memory (Flash Memory), a hard disk (Hard Disk Drive, abbreviated : HDD) or a solid-state hard drive (Solid-State Drive, SSD), etc.; the storage medium may also include a combination of the above-mentioned types of memory.

[0096] Those skilled in the art can understand that ...

Abstract

The invention discloses a flat-peak adaptive traffic control method and apparatus. In the method, in a flat-peak state, a first motorcade entering a light-controlled intersection is detected by a traffic control device arranged at the current light-controlled intersection, when there is no vehicle or pedestrian generating conflict with the first entering motorcade in the light-controlled intersection, a signal light in a light control direction where the first motorcade is located can be controlled in a green light state, and the signal light of vehicles and pedestrians in a vertical directionof the light control direction is controlled in a red light state; and the current traffic condition of the light-controlled intersection is self-adapted to ensure the traffic safety of the vehiclesand pedestrians in the vertical direction of the light control direction where the first motorcade is located, meanwhile, discrete vehicles are induced to drive into the first motorcade from the outside of the first motorcade, in order to ensure that the first motorcade can quickly pass through the current light-controlled intersection within a green light time, thereby reducing the times of the green light, and no remote transmission of traffic data is needed, thereby shortening the data transmission time and improving the traffic efficiency.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a peak-level adaptive traffic control method and device. Background technique [0002] Traffic flat peak is when the traffic flow or the number of pedestrians on the road is between the low peak and the peak traffic flow or the number of pedestrians on the road. Therefore, in the flat peak, by effectively regulating the traffic flow or pedestrian traffic in real time, it can realize Adaptive to the traffic conditions on the road, it is beneficial to improve the traffic congestion in flat peaks and improve the traffic flow or pedestrian traffic efficiency. [0003] At present, the traditional flat-peak adaptive traffic control method transmits the current traffic information to the remote server through the current traffic information of the intersection detected by the detection equipment installed at the intersection, and the remote server analyzes or calcula...
