The invention discloses a traffic flow data missing repair system evaluation and strategy design method, which comprises the following steps of: constructing different traffic flow data missing repair models considering space-time relevance and traffic flow data missing repair models not considering the space-time relevance; according to different data restoration modes, restoration analysis is carried out on missing data of traffic flow data, error indexes of different road traffic flow missing restoration models under different missing conditions are analyzed, the advantages of different traffic flow missing restoration models are combined, and a traffic flow data missing restoration general strategy with good adaptability is formulated. And a decision basis is provided for selection of a traffic flow missing repair model and formulation of a pervasive traffic flow missing repair strategy.

    本发明公开了一种交通流数据缺失修复系统评估与策略设计方法,包括构建了不同考虑时空关联性的交通流数据缺失修复模型和不考虑时空关联性的交通流数据缺失修复模型,根据不同数据修复方式对交通流数据缺失数据进行修复分析,将不同缺失情形下不同道路交通流缺失修复模型的误差指标进行分析,结合不同交通流缺失修复模型的优点,制定具有良好适应性的交通流数据缺失修复一般性策略,为交通流缺失修复模型选择和普适交通流缺失修复策略制定提供决策依据。
