Embodiment Construction

[0032] In this embodiment, a mobile APP-based pedestrian crossing warning system is applied to intersections controlled by two-phase signals without secondary crossing facilities, such as figure 1 As shown, the system includes: a traffic signal light chassis and a ground sensing coil detection device installed on the road site, and a mobile phone APP installed in the pedestrian's mobile phone;

[0033] The traffic signal light chassis includes: traffic signal light, traffic signal acquisition module, traffic signal control module, visual detection module and the first wireless communication module, wherein the traffic signal acquisition module combines the traffic signal control module to obtain the status information of the traffic signal light; the visual detection module utilizes the image The capture device converts the turning intersection conditions into image signals and sends them to a dedicated image processing system, and converts them into digital signals based on in...

Abstract

The invention discloses a pedestrian crossing warning system based on a mobile phone APP, which is designed for pedestrian crossing warning at a two-phase signal control intersection without secondarycrossing facilities. The system is composed of a traffic signal light case and a ground inductance coil detection device arranged on a road site, and a mobile phone APP arranged in the mobile phonesof pedestrians. The traffic signal light case includes traffic signal lights, a traffic signal acquisition module, a traffic signal control module, a visual detection module and a first wireless communication module. The ground induction coil detection device includes a second wireless communication module and a ground induction coil. The mobile phone APP includes a mobile phone communication module, a mobile phone GPS module, a mobile phone central processing module and a mobile phone voice module. The pedestrian crossing condition can be judged by collecting the current traffic flow condition. Pedestrians are warned so that the safety consciousness of pedestrians is improved, the dangerous situation of pedestrians during street crossing is avoided, and traffic congestion is alleviated.

Description

technical field [0001] The invention relates to the field of road traffic safety, in particular to a mobile phone APP-based pedestrian crossing warning system. Background technique [0002] At present, most of the intersections of roads in many cities in my country do not have independent pedestrian signal phase time. Pedestrians generally pass in phase synchronization with the straight-going motor vehicles. This traditional phase setting leads to serious conflicts between pedestrians and turning vehicles at intersections, especially at two At the intersection controlled by the phase signal (right-turning motor vehicles are not controlled, left-turning motor vehicles and straight-going motor vehicles are released at the same time), the conflict between turning motor vehicles and pedestrians is particularly prominent. Due to the interference of turning vehicles, pedestrians cannot accurately judge whether they can cross the street during the remaining time of the green light, ...
