Real-time microscopic traffic simulation system and method based on virtuality and reality mixing

Abstract

The invention discloses a real-time microscopic traffic simulation system based on virtuality and reality mixing. The system comprises a simulation server which is used for rendering and displaying aglobal traffic simulation scene, a number of automobile driving simulators which are used for controlling the motion of a simulated vehicle to provide a simulation server with the data information ofthe currently controlled simulated vehicle and display a local traffic simulation scene, and a traffic simulation display platform which is connected with the simulation server to display the currenttraffic situation. The invention further discloses a real-time microscopic traffic simulation method based on virtuality and reality mixing. According to the invention, the system and method have theadvantages of simple structure and reasonable design; the operation of the simulated vehicle controlled by a real driver participates in the traffic flow of traffic simulation; the driving behavior and driving habit of the real driver are reflected in traffic simulation, so that the whole traffic flow is closer to the real traffic situation; and the system and method have the advantages of easy use and operation, high practicability, good use effect and easy promotion and use.

Description

technical field [0001] The invention belongs to the technical field of traffic flow simulation, and in particular relates to a real-time microcosmic traffic simulation system and method mixed with virtual and real. Background technique [0002] With more and more cars in the city, the traffic environment is becoming more and more complex, traffic congestion, low traffic road transport efficiency, frequent traffic accidents and other phenomena, these accidents have brought serious loss of life and property to people, seriously hindered my country's social and economic development. The emergence of traffic simulation provides a safe, efficient and low-cost method to solve these problems. However, traditional traffic simulation is mostly studied from the aspect of traffic flow simulation model. By studying the vehicle following model and vehicle lane change model, a traffic flow simulation that is closer to the real situation is reflected in the simulation. However, these model...

Problems solved by technology

However, the traditional traffic simulation is mostly studied from the aspect of the traffic flow simulation model. By studying the vehicle following model and the vehicle lane change model, a traffic flow simulation that is closer to the real situation is reflected in the simulation, but these models are different from real traffic. There are some differences
