大数据时代交通模型发展趋势及体系变革的思考

Future Development and System Change of Transportation Model in the era of Big Data

交通模型作为交通规划领域最主要的技术工具,在中国已有近40年的发展历程,在交通规划定量分析方面发挥着不可替代的作用。在大数据迅猛发展的时代背景下,传统交通模型体系及建模技术已无法适应大数据应用及精细化规划决策的需求。本文分析了当前交通模型发展面临的关键问题,结合我国实际情况揭示了未来我国交通模型行业发展趋势,并从数据基础、软件平台、建模理论、模型功能、应用场景等整个模型体系角度提出了大数据背景下交通模型发展的方向及对策。

As the most important technical tool in the field of transportation planning, the transportation model has been developed in China for nearly 40 years, which plays an irreplaceable role in the quantitative analysis of transportation planning. Under the background of the rapid development of big data, the traditional transportation model system and modeling technology can not adapt to the needs of big data application and fine planning decision-making. The paper analyzes the key problems facing the development of the current traffic model. Combined with the actual situation of our country, the development trend of Chinese transportation model industry is revealed. From the perspective of data foundation, software platform, modeling theory, model function, application scenario and so on, the development direction and countermeasure of transportation model under the background of big data are put forward.
