Embodiment 1

[0045] Embodiment 1, this embodiment proposes a one-way street intelligent traffic light control method based on the end of pedestrian traffic, which specifically includes the following steps:

[0046] (1), separate traffic signal lights are respectively set up for each sub-lane of the one-way street, and the whole sidewalk is divided into a plurality of unit modules according to the number of sub-lanes, that is, each unit module corresponds to its relative sub-lane; refer to figure 1 , is a schematic diagram of a one-way road model. In the figure, the one-way road includes three sub-lanes, which are marked as ①②③. Each sub-lane has a corresponding traffic signal light for separate control. The traffic signal light corresponding to the lane is B light, and ③ the traffic signal light corresponding to the lane is C light. Correspondingly, the sidewalk is divided into three unit modules;

[0047] (2) When the passing time of the green light for pedestrians reaches the set end-of-...

Embodiment 2

[0066] Embodiment 2, based on the one-way street intelligent traffic light control method described in embodiment 1, this embodiment proposes a one-way street intelligent traffic light control system based on the end of pedestrian traffic, refer to figure 2 , which is a functional block diagram, including a pedestrian detection device, a vehicle detection device, a control unit and a traffic signal light, the output terminals of the pedestrian detection device and the vehicle detection device are connected with the input terminal of the control unit, and the traffic signal light is connected with the output terminal of the control unit Connected, the traffic signal lights include multiple groups, which are respectively installed on each lane of the one-way street, so as to realize the separate control of each lane; in addition, the entire sidewalk is divided into multiple unit modules according to the number of lanes.

[0067] The pedestrian detection device 5 is set on one si...

Abstract

The invention relates to a one-way street intelligent traffic light control system and method based on the last stage of sidewalk passage. The control system comprises a control unit, a pedestrian detection device and a vehicle detection device, and independent traffic lights are arranged for each divided lane; pedestrians and vehicles are subjected to real-time detection and data analysis respectively with an infrared detection technology and a wireless geomagnetic sensing technology; vehicle information data is accurately detected by means of set position design of wireless geomagnetic sensors, a sidewalk is subjected to corresponding module division according to the number of the divided lanes, image data is analyzed according to combination of a sidewalk coordinate system and an imagepixel plane-coordinate system, accurate pedestrian information data is acquired, the pedestrian information data and the vehicle information data are transmitted to the control unit for safety analysis and judgment, the traffic lights of the divided lanes are independently controlled, so that control operation such as red time lengthening and the like is executed, vehicles are allowed to pass after clear passage of the pedestrians, safety of pedestrian passage is effectively improved, and the system and the method have greater practical significance and broad market application prospect.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic, in particular to an intelligent traffic light control system and control method based on pedestrian and vehicle detection. Background technique [0002] With the development of the times, today's vehicles are all over thousands of households. Although cars provide great convenience for people to travel, frequent traffic accidents have brought serious problems to people's travel. Especially at the end of the sidewalk traffic (the time period when the green light passing time on the sidewalk is about to end), pedestrians on the sidewalk have insufficient estimation of the passing time and cannot pass the sidewalk during the green light passing time, while the vehicle drivers on the lane will be affected by the vehicles in the side lane There is a visual blind spot and pedestrians in the sidewalk cannot be found in time, and traffic accidents are very likely to occur at this time. At pr...
