Implementation Method of Mesoscopic Dynamic Traffic Simulation Based on Dynameq Software

宏观交通模型主要用于研究大范围城市与交通规划和建设引起的中长期交通需求变化,而微观交通仿真适用于研究小范围高精度和基于个体的动态交通分析评估和可视化展示。随着基于多源大数据的大范围内动态交通分析技术逐步成熟,能较好的满足城市精准化量化分析预测的需要。对中观动态交通仿真技术涉及的关键数据和技术方法进行梳理,研究基于Dynameq软件进行中观动态交通仿真的流程和方法,为完善城市宏观—中观—微观一体化交通模型体系、提升城市交通量化分析精度和效率提供思路,并以示范区域为仿真对象进行验证。

Macroscopic traffic model is mainly used for large-scale area and long term traffic demand forecast caused by large-scale traffic planning and construction, while microscopic traffic simulation is mainly used for individual dynamic traffic analysis and display with small range and high precision. With the gradual maturity of large-scale dynamic traffic analysis technology based on multi-source big data, it can better meet the needs of accurate quantitative analysis and prediction in important district. This paper combeds the mesoscopic dynamic traffic simulation technology involved in the key data and technical methods and studies the methods of mesoscopic dynamic traffic simulation based on the Dynameq software, which will improve urban macro-meso- microscopic traffic simulation system, and promote the urban traffic simulation precision and efficiency. The method of the mesoscopic transportation simulation is verified in the simulation demonstration area.
