terrain vehicle
3.A small, all-terrain motor vehicle seating one person and having four wheels with large tires.
6.A road traffic noise analysis method and system is introduced, based on the technology of SDTM (synthetic digital terrain model) and line source equivalent substitution and dispersion of stochastic vehicle flow. A geometric design and optimization method of road noise barriers based on the system is proposed in detail. With this method, we can approximately simulate the influences of various environmental conditions, such as buildings, topographic, vegetable covers, and so on.
7.Abstract: The architecture of GIS for navigation of autonomous vehicle and the management method of spatial data are presented in the paper.By using the object-oriented technique，class library is designed.which is the abstract of terrain model and spatial data management model.And the system is built on base of the class library.
8.This paper presents a comprehensive vehicle model for automobile emulated driving based on DirectX. Technologies such as modeling and simulation、DirectX and collision detection were tested in the building of visual automobile emulated driving simulation model. The main content is a real time simulation model、terrain detection arithmetic、 the strategy of steering control and logical estimation of shift change for 3D environment application.
