实时准确可靠的短时交通流预测是智能运输系统的基础。根据短时交通流预测建模的研究现状,探讨了影响短时交通流预测建模的七个方面要素,进而提出了短时交通流预测的“四阶段法”建模策略。对短时交通流预测建模的梳理有助于改进现有模型以及研发新的模型。 Real-time accurate and reliable short-term traffic flow prediction is the basis of intelligent transportation system. According to the research status quo of short-term traffic flow forecasting modeling, this paper discusses seven factors that affect short-term traffic flow forecasting modeling, and then proposes a “four-stage modeling” strategy for short-term traffic flow prediction. Combining the modeling of short-term traffic flow prediction helps to improve existing models and develop new models.
