The invention discloses an expressway interleaving area lane level conflict prediction method based on real-time traffic flow data, and the method comprises the following steps: S1, selecting a proper expressway interleaving area as an investigation site, and carrying out the field investigation; s2, collecting traffic flow data and traffic conflict data of each lane, and defining threshold values of different conflict types; s3, building a traffic simulation model by using the traffic parameters obtained by investigation, delimiting different conflict types according to the conflict threshold obtained in the step S2, and obtaining different types of traffic conflict data; s4, extracting characteristic variables according to the data obtained in the step S3, and constructing a data set of different conflict type prediction models; s5, constructing a conflict analysis model; and S6, constructing a conflict prediction model. According to the invention, real-time traffic conflict prediction of the lane level of the expressway interleaving area can be realized, more accurate lane level conflict risk information can be provided for driving vehicles in each lane, and drivers are helped to select safer lanes and paths for driving.

    本发明公开了一种基于实时交通流数据的快速路交织区车道级冲突预测方法,包括以下步骤:S1,选择合适的快速路交织区作为调查地点,进行实地调查;S2,采集各车道的交通流数据和交通冲突数据,划定不同冲突类型的阈值;S3,利用调查获取的交通参数搭建交通仿真模型,根据步骤S2中获取的冲突阈值划定不同冲突类型,并获取不同类型的交通冲突数据;S4,根据步骤S3获取的数据,提取特征变量,构建不同冲突类型预测模型的数据集;S5,构建冲突分析模型;S6,构建冲突预测模型。本发明可以实现对快速路交织区车道级的实时交通冲突预测,进而可以为各车道驾驶车辆提供更加精确的车道级别冲突风险信息,帮助驾驶员选择更加安全的车道和路径行驶。
