摘　　要：根据道路交通流参数与道路交通状态之间的关系,又由道路上交通流量数据,可以很方便地采用数据驱动的方法来评价道路交通状态.首先建立层次结构的评价层次,然后给出各层次计算公式,从而确定各指标权重,最终得出人对道路运行状态的感觉变化规律的评价集结果.通过实例分析说明,数据驱动对道路运行状态的推理评价是客观合理、科学可行和公正实用的.According to the relationship between traffic flow parameters and road traffic running state and the data of traffic flow on road, it is commodious to evaluate road traffic conditions with some data-driven approach. Firstly, evaluation levels of hierarchical structure are established. Then all levels＇ calculation formulas are providedto determine various index weight. Eventually the evaluation sets of people＇ feeling change on running road status are worked out. The analyses on the examples show that the data-driven evaluation on road running state reasoning evaluation is objective, reasonable, scientific, feasible and practical.
