The invention relates to a highway special event traffic situation perception and discrimination method based on ETC data. The method comprises the following steps: 1) extracting historical data of a special event occurring in a highway section in a certain period and historical data of an ETC portal; 2) performing data conversion and treatment on the historical data, and establishing a special event historical database and a traffic information historical database; 3) obtaining a historical traffic situation threshold X and a historical influence degree threshold Y based on the special event historical database and the traffic information historical database; 4) analyzing the real-time traffic state to obtain a real-time traffic situation threshold Xs in the real-time traffic state; and 5) comparing the real-time traffic situation threshold value Xs with the historical traffic situation threshold value X, and obtaining a real-time influence degree threshold value Ys based on the historical influence degree threshold value Y. According to the method, the timeliness and the accuracy of distinguishing the special events in the expressway can be improved, and the operation state of the expressway can be well reflected.

    本发明涉及一种基于ETC数据的高速公路特殊事件交通态势感知与判别方法,包括以下步骤:1)、提取高速公路路段一定时期内发生特殊事件的历史数据及ETC门架历史数据;2)、对历史数据进行数据转换及治理,建立特殊事件历史数据库和交通信息历史数据库;3)、基于特殊事件历史数据库和交通信息历史数据库,得到历史交通态势阈值X和历史影响程度阈值Y;4)、分析实时交通状态,得到实时交通状态下的实时交通态势阈值Xs;5)、对实时交通态势阈值Xs与历史交通态势阈值X进行比对,并基于历史影响程度阈值Y以获得实时影响程度阈值Ys。其有助于提升高速公路中特殊事件判别的及时性与精确度,并能够很好地反映出高速公路的运营状态。
