Problems solved by technology

In this technical solution, there are mainly the following problems. When the signal light of the pedestrian crossing changes from green to red, it will go through the process of flickering the green light. However, in the prior art, the green light flickers for a fixed length of time, and pedestrians often fail to pass the intersection signal light. Turning to red light, or pedestrians have all passed the intersection, the signal light is still flashing green, while the motor vehicle signal light in the other direction is still red light, which affects the control efficiency of signal light

Embodiment 1

[0035] This embodiment provides a control method capable of adaptively adjusting the time of pedestrian crossing signals, such as figure 1 shown, including the following steps:

[0036] S1: Carry out video tracking of pedestrians around the intersection, the video tracking range includes the crossing waiting area set around the intersection and the crosswalk in the intersection.

[0037] S2: judge in real time whether there are pedestrians standing in the crossing waiting area, waiting to pass; if so, go to step S3, otherwise go to step S5.

[0038] S3: Determine whether the crosswalk signal light is green, if it prompts pedestrians who need to cross the street to pass through the intersection as soon as possible, and pedestrians who do not need to cross the street stand outside the crossing waiting area, then return to step S1; otherwise, enter step S4.

[0039] S4: Determine whether the motorway signal light has just turned green, if so, set the pedestrian crosswalk signal ...

Embodiment 2

[0049] This embodiment provides a control system capable of adaptively adjusting the time of a pedestrian crossing signal, including:

[0050] The video tracking unit is used for video tracking pedestrians around the intersection, and the video tracking range includes the crossing waiting area set around the intersection and the crosswalk in the intersection. The video tracking unit is set up like figure 2 shown.

[0051] The first judging unit is used for judging in real time whether there are pedestrians standing in the crossing waiting area, waiting to pass.

[0052] The second judging unit is used for further judging whether the crosswalk signal light is a red light when the first judging unit judges that there is no pedestrian standing in the crossing waiting area.

[0053] The first processing unit is used to keep the pedestrian crossing signal light as red when the second judging unit judges that the pedestrian crossing signal light is red, and prompt crossing pedest...

Abstract

The invention discloses a control method and a control system capable of adaptively adjusting street crossing signals for pedestrians. The pedestrians around a road junction are continuously tracked through video tracking detection technology. A video tracking range comprises a street crossing waiting area and a pedestrian crosswalk, and a detection range is enlarged. By adopting the technical scheme, the pedestrians on the pedestrian crosswalk can be tracked and monitored in real time, twinkling time of a green lamp is adjusted according to the fact whether the pedestrians on the pedestrian crosswalk completely cross the road junction, and the pedestrians on the pedestrian crosswalk can completely cross the road junction within the twinkling time of the green lamp on the premise that waste of the twinkling time of the green lamp can be avoided when no pedestrian walks on the pedestrian crosswalk.

Description

technical field [0001] The invention relates to the field of pedestrian crossing signal control, in particular to a control method and system capable of adaptively adjusting the time of pedestrian crossing signal. Background technique [0002] With the rapid development of social economy and the continuous growth of urban population, the demand for people to walk through intersections continues to increase. In order to ensure the safety of pedestrians, large and medium-sized cities at home and abroad generally use pedestrian crossing light control to provide pedestrians with safe crossing passages. At present, in order to improve the efficiency of intersection traffic, many cities in China have installed pedestrian signal request buttons at intersections controlled by pedestrian crossing lights. Reduce the green time lost for pedestrian crossings. If a pedestrian wants to cross the street and does not know how to press the request button, he will never get a green light sig...
