Problems solved by technology

[0002] When studying traffic behavior, it is very difficult and error-prone to use the mathematical model method to analyze traffic behavior theoretically, and the field experiment is limited by the conditions of the actual scene and has great safety hazards. Therefore, the simulation experiment is very important when studying traffic behavior. most commonly used...

specific Embodiment

[0083] This experimental example is a simulation experiment of pedestrian crossing traffic behavior at an unsignalized intersection based on virtual reality technology. In real life, pedestrians need to observe the distance between themselves and passing vehicles when crossing the street at an unsignalized intersection, so as to choose whether to cross the street and the timing of crossing the street. There are differences in the crossing behavior of people of different ages, personalities, and psychological states. Some people are more likely to rush forward when crossing the street, and thus have a higher probability of accidents. Pedestrian crossing experiments in the real environment have greater safety risks, so the simulation experiment based on virtual reality technology is an effective way.

[0084] Such as figure 2 As shown, the specific implementation steps are as follows:

[0085] Step 1: Construct the experimental scenario according to the research content.

Abstract

The invention relates to an immersive pedestrian traffic behavior experiment platform and method based on a virtual reality technology. The platform is composed of a scene construction module, head-mounted VR glasses, a universal walking pad, a 3D camera device, an action recognition module, a control module, a data collection and export module and a physiological data sensor. The invention also provides a pedestrian traffic behavior experiment method based on the virtual reality technology, and the method comprises the steps: 1, experiment scene construction: selecting a reconstruction mode based on a real scene or directly employing a simulation software compiling mode for the construction of the experiment scene according to the experiment requirements; 2, parameter setting: according to experiment requirements, event insertion and related parameter setting are carried out on an experiment scene; 3, equipment connection and test: operating control software to complete port test andconnection test, and establishing connection for control programs of different equipment; 4, formal experiment and data acquisition. Compared with the prior art, the platform and the method have the advantages of fitting the actual situation, being high in experiment environment authenticity and the like.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic systems, in particular to an immersive pedestrian traffic behavior experiment platform and method based on virtual reality technology. Background technique [0002] When studying traffic behavior, it is very difficult and error-prone to use the mathematical model method to analyze traffic behavior theoretically, and the field experiment is limited by the conditions of the actual scene and has great safety hazards. Therefore, the simulation experiment is very important when studying traffic behavior. The most commonly used means. According to research, most of the research on traffic behavior in China is currently carried out on vehicle drivers. The driving simulator experiment platform is relatively mature, but there is little research on pedestrian traffic behavior, and there is a lack of simulation experiments on pedestrian traffic behavior from the perspective of pedestrians. platf...
