Embodiment Construction

[0018] Through the video acquisition module, the data collected by the camera is preliminarily extracted and processed, and the preliminarily collected data is extracted from the trajectories of pedestrians crossing the street, and the temporal and spatial trajectories of pedestrians are drawn to analyze the factors affecting pedestrian trajectories. The analyzed results are then processed by relevant algorithms, and then the basic behavior model of pedestrians can be obtained. In addition, the violation probability prediction module is used to calculate the violation probability of people and vehicles, and based on this, the comprehensive benefit index of pedestrian crossing is established through the algorithm of the present invention, so as to evaluate the traffic situation of pedestrian crossing. Specific steps are as follows.

[0019] Step 1: Use high-definition cameras to collect pedestrian crossing data. Input the captured video into the "Pedestrian Trajectory Tracking...

Abstract

The invention provides a pedestrian motion trail detection and violation analysis system and relates to systems for trail detection and violation analysis during pedestrian crossing. A video collection module, a behavior trail processing module and a violation behavior analysis module are adopted to jointly form the pedestrian motion trail detection and violation analysis system, wherein the video collection module contains a high-definition camera, a tripod and a connecting line; the behavior trail processing module contains a data extraction module, a data conversion module and a trail description module for converting pedestrian behavior characteristic parameters into a pedestrian crossing trail graph; and the violation behavior analysis module contains a data extraction and conversion module capable of extracting traffic parameters in violation behaviors, a violation probability prediction module and a passage efficiency analysis module under different violation probabilities. Through the system, pedestrian crossing trail detection and crossing violation analysis are realized, a user can track and detect a pedestrian crossing trail by means of video collection and perform behavior analysis and expression, and therefore the convenience of pedestrian behavior analysis is improved.

Description

Technical field [0001] The invention relates to the field of traffic behavior analysis, and more specifically to a track detection and violation analysis system for pedestrians crossing the street. Background technique [0002] At present, traffic behavior analysis mainly uses social force model, magnetic force model, queuing theory and microscopic simulation methods to conduct theoretical analysis on the trajectory of motor vehicles and pedestrians and violations. However, the behaviors of people and vehicles are quite different, and the existing theories tend to be relatively unified in the research methods of the two, and most of them focus on the behavior of motor vehicles. However, pedestrian crossing trajectories are flexible in actual traffic, and only the theory or simulation of motor vehicles cannot truly express the changing laws of human behavior. In addition, there are few studies on the causes and consequences of illegal behaviors in people and vehicles crossing...
