Embodiment Construction

[0024] The invention uses a high-performance computer, a graphics workstation and a vehicle driving simulator as hardware platforms, and adopts technologies such as micro-traffic simulation, artificial intelligence, vehicle dynamics, visual simulation, and digital audio. The main process is as follows:

[0025] 1. Carry out surveying and surveying of the traffic area that needs to be simulated, obtain corresponding basic data, and store these data in the traffic environment database. These basic data include: data on roads, signal lights, traffic signs, traffic rules, etc. The road data includes the geometric information of the road, lane division, road surface material and additional attributes, road elevation, speed limit information, etc.; the signal light data includes the number, type, distribution position, signal timing, etc. of signal lights; the traffic sign data includes: sign type, Geometric information, location distribution, etc.; traffic rules include the rules ...

Abstract

The invention aims at providing a distributed interactive traffic simulation system which is a new traffic-driving simulation system. The key point of the traffic simulation system lies in introducing a vehicle driving emulator on the route of the user into the traffic simulation system as a traffic entity. The vehicle driving emulator, as a traffic entity controlled by the driving of the user, interacts with the virtual traffic entity produced by the traffic simulation system, and the traffic entity and the virtual traffic entity together participate in traffic simulation calculation, thus realizing cooperated simulation of a plurality of vehicle driving emulators and a plurality of traffic condition simulation servers under the same virtual traffic condition. The distributed interactive traffic simulation system is flexible in structure, convenient to extend and is high in simulation credibility and supports man-machine interaction. The system not only can be applied to traffic simulation and driving simulation but also provides a new platform for the research and application in the field of driving behavior, driving mentality, traffic safety, intelligent traffic, as well as road and bridge design.

Description

technical field [0001] The invention relates to the technical field of simulation, in particular to the fields of traffic simulation and vehicle driving simulation. Background technique [0002] Since the 1980s, many developed countries have used computer simulation technology in the fields of national defense, aviation, and aerospace. In the 1990s, it began to be popularized and applied to civilian fields such as energy, transportation, and electric power. [0003] The use of computer simulation technology to study traffic problems has the characteristics of economy, safety and high efficiency. At present, in the field of highway traffic, computer simulation technology is mainly used in two aspects of traffic simulation and driving simulation. The traffic simulation system solves problems in traffic management, road planning, traffic impact assessment and other fields by simulating the dynamic characteristics of the road network and traffic flow, and is usually implemente...
