Problems solved by technology

[0005] The present invention solves the problem in the prior art that pedestrians arrive at the intersection, the motor vehicle signal light has already turned green, and the pedestrian presses the request button and can only get the pedestrian signal green light when the motor vehicle signal light turns on next time, thereby providing A street-crossing signal control method and system capable of meeting the needs of pedestrians

Embodiment 1

[0045] This embodiment provides a method for controlling street crossing signals that can meet the needs of pedestrians, such as figure 1 shown, including the following steps:

[0046] 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.

[0047]S2: judge in real time whether there are pedestrians standing in the crossing waiting area and wait to pass; if so, enter step S3, otherwise set the sidewalk signal light to red and prompt crossing pedestrians to stand in the crossing waiting area and then return to step S1.

[0048] S3: Determine whether the sidewalk 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 waiting area for crossing the street, then return to step S1; otherwise, go to s...

Embodiment 2

[0062] This embodiment provides a street crossing signal control system that can meet the needs of pedestrians, including:

[0063] 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 setting mode of described video tracking unit can be as follows image 3 the form shown.

[0064] The first judging unit judges in real time whether there are pedestrians standing in the crossing waiting area, waiting to pass.

[0065] The first processing unit, when the first judging unit judges that there is no pedestrian standing in the crossing waiting area, sets the sidewalk signal light to red and prompts pedestrians to stand in the crossing waiting area.

[0066] The second judging unit further judges whether the sidewalk signal light is a green light when the first judging unit judges that there are pedestrians standin...

Abstract

The invention provides a method and a system for controlling street crossing signals and capable of meeting requirements of pedestrians. The method for controlling the street crossing signals and capable of meeting the requirements of the pedestrians is characterized by continuously tracking the pedestrians around a road junction 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, as long as the pedestrians wait in the street crossing waiting area and even though a motor vehicle road signal lamp turns green, a green lamp traffic signal can still be provided to the pedestrians if remaining time of the green lamp can guarantee that the pedestrians can safely cross a street, and street crossing efficiency of a motor vehicle can not be influenced on the premise that waiting time of the pedestrians is reduced.

Description

technical field [0001] The invention relates to the field of pedestrian crossing signal control, in particular to a street crossing signal control method and system that can meet the needs of pedestrians. 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. Green time lost for pedestrians crossing the street. 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 signal. If t...
