Pedestrian crossing warning system based on mobile phone APP

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, ...
