为解决高速公路交通状态识别问题,提出一种省级高速公路交通状态的识别与推理方法,该方法首先对大量交通流历史特征数据进行预处理,然后建立基于一种塔式结构的交通流特征数据提取模型。通过系统开发,实现了某路段的分析,表明可实现高速公路运行状态的识别。该识别与推理方法将用于省级高速公路联网应急联动平台,有较好的应用前景。
In order to solve the problem of expressway traffic status identification, this paper proposes a method of provincial expressway traffic status identification and reasoning. The method firstly preprocesses a large amount of traffic flow historical feature data and then establishes traffic flow characteristics based on a tower structure Data extraction model. Through the development of the system, the analysis of certain road sections is realized, which shows that the running status of expressways can be identified. The identification and reasoning method will be used in the provincial highway network emergency linkage platform, has a good application prospects.
