关于宏观交通模型中若干关键技术的思考

Thoughts on Some Key Technologies in Macroscopic Traffic Model

在构建宏观交通模型过程中,除了输入数据外,一些关键技术环节,如交通小区的划分,通勤交通出行强度的确定方法等等,也对最终交通模型的质量起着关键作用。本文结合工作经验,对宏观交通模型中若干关键技术环节进行思考和分析,探讨项目实际可用资源在受到约束的条件下,如何科学合理地优化和完善这些关键技术环节,以提高交通模型的预测能力。

In the process of building a macro traffic model,in addition to the input data,some key technical links,such as the division of traffic zones,the determination of commuter traffic intensity,and so on,also play a key role in the quality of the final traffic model. Based on the work experience,this paper thinks and analyses some key technical links in the macro traffic model,and discusses how to optimize and improve the key technical links scientifically and rationally,so as to improve the forecasting power of the traffic model.
