城市交通微观模拟系统可以为城市交通管理决策提供依据 ,使城市交通逐步纳入科学管理的轨道。文章对交通流微观模拟系统的基础——模拟路网进行了深入的研究 ,在了解了实际网络构成的基础上 ,对宏观路网及微观路网进行了分类定义 ,描述了路网组成元素的属性 ,并应用现代计算机技术 ,实现了在背景地图上的路网矢量化、可视化设计。
Urban traffic micro-simulation system can provide the basis for decision-making of urban traffic management, so that urban transport is gradually incorporated into the track of scientific management. The article makes an in-depth study of the simulated traffic network, which is the basis of traffic flow micro-simulation system. Based on the understanding of the actual network structure, the paper defines the macro-road network and micro-road network, Attributes, and the application of modern computer technology, to achieve the background of the road network vectorization, visual design.
