基于OriginPro的交通流NaSch模型的仿真开发

Simulation Development of Traffic Flow NaSch Model Based on OriginPro

在分析Origin C语言体系结构及OriginPro辅助开发工具的基础上,针对交通流中经典的NaSch模型进行了系统仿真的二次开发。应用Origin C设计了模型中的主要类,借助OriginPro对象开发了模型的界面输入和输出函数,实现了模型的两个主要模拟结果:流量-密度图和时空相位图,并指出了进一步的研究方向。

On the basis of analyzing Origin C language system and OriginPro assistant development tools, NaSch model which is a classical one in the traffic flow models is secondarily developed. The main class of the model is designed using Origin C, while the input dialog and output functions are built in OriginPro. Finally, the two main simulation results including flow-density diagram and time-space diagram are implemented. Orientation of d further study is pointed out.
