Integrated network experiment platform for integrating microcosmic traffic simulator with multiple driving simulators

Abstract

The invention relates to an integrated network experiment platform for achieving functional integration of a microcosmic traffic simulator and multiple driving simulators. According to the integrated network experiment platform for integrating the microcosmic traffic simulator with the multiple driving simulators, each driving simulator which serves as a branch control console detects and records driving behavior parameters of a corresponding driver and the state of a test car in real time and then sends the information to the microcosmic traffic simulator which serves as a main control console through the network communication protocol; after the information input each time is processed by the microcosmic traffic simulator, current traffic flow parameters are analyzed and calculated and then are fed back to each driving simulator; after the road network traffic flow parameters received by the driving simulators are visualized, the drivers can see vehicles near the test cars on the display screens of the driving simulators, and then the drivers can make driving decisions according to the provided information. The integrated network experiment platform for integrating the microcosmic traffic simulator with the multiple driving simulators has the advantages that limitation that a traditional driving simulator can only be used for studying driving behaviors of a single driver is broken through, and the study of the influence of the driving behaviors of multiple drivers or a specific group of drivers on the state of the whole traffic flow is available; due to the fact that the microcosmic traffic simulator is integrated with the multiple driving simulators, simulation of the traffic flow near each test car is more vivid, and the experimental capacity of the driving simulators to the traffic flow operation behaviors is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic systems and traffic simulation, and more specifically, the invention relates to an integrated network experiment platform for realizing the integration of a microscopic traffic simulator and multiple driving simulators. Background technique [0002] The road traffic system is a complex system composed of four elements: people, vehicles, roads, and traffic environment. These elements act independently and restrict each other, and jointly determine the operation status of this complex system. It is very difficult to theoretically analyze the traffic system by using mathematical models in the traditional way, and the field demonstration is limited by the conditions of the actual scene, the implementation cost is high, and the safety is not high. Therefore, it is a new method to conduct experimental research on driving behavior. technical means. The development of virtual reality technolo...

Problems solved by technology

However, this invention has great limitations: firstly, the ability of a single vehicle to influence the overall traffic flow is limited; secondly, most of the driving behavior is not the individual behavior of a certain vehicle, but a group behavior Group behavior, such as lane change behavior Design multiple vehicles in the own lane and the target lane; and this invention cannot conduct high-precision virtual experiments on the interactive behavior of such multiple vehicles, so its practical value is also limited

It not only solves the shortcoming that the micro-traffic simulator cannot reflect the diversity of human behavior in real time, but also overcomes the limitations of the traditional driving simulator that the single vehicle has little influence and cannot study the influence of the vehicle group on the traffic flow
