In this paper, a firefighting tactical training simulation environment which provides high-immersion and interactive 3D virtual disaster scenes as the core was developed. Specific technical requirements on the platform architecture, hardware implementation, software functionality, application mode, and platform-based training mode, types of trainees and training evaluation methods are also proposed...
The major industrial accidents have occurred from time to time, which has a serious threat to people's property and lives. This paper builds a major hazard management system based on 3DGIS, does some research about the system structure and the key technology, and analyzes and designs the main system's functions and database. The system displays and manages a variety of basic information and data of...
There are frequent accidents at the Liuxia section of the highway around Hangzhou City, that is from the 68th kilometer to the 75th kilometer. We consider creating a model of the road in Vissim, a program of traffic simulation, collecting the parameters of vehicles and analyzing the data in Matlab. Taking the standard deviation of vehicle speed as main referred index, the speed of vehicles at the...
Tailings are major hazard in the event of dam-break accident, which once happened would lead to significant casualties, property damage and environmental pollution in downstream area. Two-dimensional GIS constrained by the spatial expression and data structure cannot be effectively used to describe the topography of tailing dam, dam body, hydro-geological and other spatial data information, which...
In the method of driving simulation, behavioral characteristics of driver can be learned safely even under abnormal state. This kind of experimental method also contributes to analyze driver's emergency response in a variety of complex conditions and it has a good experimental reproducibility, which can be applied in traffic safety, accident reconstruction, ergonomics and other fields. The combination...
The quality of road traffic accidents appraisal is not only related to the analysis accident causes, the impartiality dealing with traffic accidents, but also related to some major issues such as safeguarding the authority enforcing the law, maintaining the government's prestige, and promoting legalization of traffic management. To solve the limitation and applicability of the traditional method of...
The leakage and diffusion accident of inflammable and explosive toxic gas has become a serious problem in the field of environment and security. Based on the optimized three-dimensional finite element model (FEM3) and the actual condition in complex and sealed space, a three-dimensional simulation system is developed to simulate the dynamic process of leakage and diffusion of gas in complex and sealed...
A serious highway accident with long duration will lead to a great delay. If the extended travel time is beyond travelers' tolerance, they will make a detour by choosing any other roads. However, the driver's behavior of taking other routes will make an impact on the surrounding road network. Thus that impact is called the indirect impact by highway traffic accidents in road network. The range of...
Decreasing traffic accidents and events are one of the most significant responsibilities for most of the government in the world. Nevertheless, it is hard to precisely predict the traffic condition. In order to understand the real cause of traffic accidents and restore the occurrence of traffic events, a traffic monitor and event analysis mechanism based on 3D video processing techniques is proposed...
The fatigue crack easily occurs in the nodes of the steel truss bridges which are under long-term load of moving train, it may endanger the safety of a bridge and even lead to its collapse. Therefore, it is essential to research on it. This paper introduces the detailed procedures of modeling a 3-D straight through crack in a node of a steel truss bridge by using the commercial FE software ANSYS with...
With the coming of information age and the extensive application of virtual reality technology, there is a growing concern to e-learning. In the field of virtual reality technology, 3D e-learning for children is becoming a hot topic. In recent years, traffic accidents occur frequently in China, causing a large number of casualties and property losses. Because of children's special characteristics,...
The development of appropriate training schemes and scenarios for computer-based training in the use of new Advanced Driver Assistance Systems (ADAS), has been one of the many objectives of the TRAIN-ALL (European Commission-EC co-funded) project. In order to make drivers familiar and able to use the in-vehicle driver support systems, specific simulator scenarios have been built, along with the use...
Sudden leakage has become a growing threat to public safety in cities. In our study, constructing a model of three-dimensional dynamic diffusion of leaked pollution gas, and exploring key technologies for space-time evolution of leakage diffusion, we implemented the visual processing of positioning and monitoring of regional pollution and also implemented the visual presentations and interpretation...
With the development of automotive industry and transportation, the safety of transportation is huge invisible trouble by bringing great convenience to human being for many years. As result, the reappearance for the simulation of traffic accidents scene is essential. On the other side the reappearance of traffic accidents is not only the method to evaluate the responsibility, analysis the cause, but...
This paper briefly introduced the characteristics and importance of virtual reality, and discussed traffic problem in reality, then focused on the feasibility and realistic significance of the application of virtual reality technology in Transportation. Furthermore, by theoretically simulating traffic situations in bad weather and predicting varied scenes of traffic flow with virtual reality technology,...
There exist generally low fidelity, function insufficiency, deficient effect etc to the existing substation training simulator. We present a novel full-functional virtual simulation training system of substation by means of three-dimension virtual simulation technology, database technology. During the course of realizing numerous training cases, DOF, multi-channel technology are adopted to reappear...
Driving at night time increases the risk of accidents because the driver's perception is reduced to the limited area of the environment which is illuminated by the car's head lights. In the study presented in this paper, the tool Vehicle in the Loop (VIL) is used the first time to research the potential of a new light function. VIL is a Virtual Reality application and simulation setup which allows...
Virtual Reality technology is increasingly being used in mining data visualization, accident simulation, miner training, equipment simulation, and risk evaluation in mining industry. However, little attention has been paid on modeling risk behaviors in underground coalmine. Based on Multi-agent technology, a hierarchical architecture for modeling the risk behaviors in coalmine virtual environment...
This article establishes mine workers' safety behaviors simulation system through combines virtual reality and mining safety production. The aim is to standardize safety behavior, improve the effectiveness of safety training and accordingly reduce the accidents' occurrence in coal mine. The system is constructed by means of 3D building software. Then, an integrated development in the platform Virtools...
High level architecture (HLA) is general purpose architecture for distributed computer simulation systems independent of platform.
