交通工程CAE软件系统的设计与实现方法

Design and realizing method of traffic engineering CAE system

在分析交通工程软件系统现状的基础上,给出了基于GIS(地理信息系统)平台的交通工程CAE(计算机辅助工程)软件系统的设计方案,对系统设计中的关键技术进行了分析,采用数值逼近理论分析交通数据,并以智能化图形方式显示结果。实例中通过对交通特性中行车速度的分析与处理,证明了该系统整体方案及交通数据组织与拟合算法的可行性。

Based on the analysis of the current development of traffic engineering software system, the traffic engineering CAE(computeraided engineering) systematic designing program based on GIS(geological information system) was presented, and the key technology of the design was also given. The process and analysis of traffic data were made with numerical analyzing theory, and its results were expressed in intelligent model. The system is proved to be feasible by analyzing and dealing with vehicle speed in traffic properties.2 tabs,7 figs,8 refs.
