The invention relates to the technical field of intelligent traffic, in particular to an urban road vehicle lane changing intention recognition system and method.The urban road vehicle lane changing intention recognition system comprises a data collecting and processing module, a feature extraction module and an intention recognition module, and lane changing intention recognition is conducted through cooperative work of the three modules; specifically, the data acquisition and processing module collects data from various sensors, carries out standardization processing, and carries out smoothing processing on the sensor data by using a Savitzky-Golay filter. The feature extraction module captures the relationship between different features in input data by using a Transform encoder and extracts important features related to a lane changing intention for the problem of insufficient target feature extraction. The intention recognition module uses a BiGRU model combined with an attention mechanism to carry out weight matching on the important features and finally uses a Softmax function to calculate the driving intention of the target vehicle; a lane changing intention recognition method is formed in the processing process of each module. According to the invention, the identification accuracy and real-time performance of the lane changing intention are improved.

    本发明涉及智慧交通技术领域,具体涉及一种城市道路车辆换道意图识别系统及方法,包括数据采集与处理模块、特征提取模块和意图识别模块,通过三个模块的协同工作进行换道意图识别,具体为数据采集与处理模块收集来自多种传感器的数据,进行标准化处理并用Savitzky‑Golay滤波器对传感器数据进行平滑处理。特征提取模块针对目标特征提取不充分的问题,使用Transformer编码器捕捉输入数据中不同特征之间的关系,提取与换道意图相关的重要特征。意图识别模块使用结合注意力机制的BiGRU模型对重要特征进行权重匹配最后利用Softmax函数计算出目标车辆的驾驶意图;各模块的处理过程形成了换道意图识别方法。本发明提升了换道意图的识别准确性和实时性。
