基于物联网的城市交通突发事件的检测研究

Research on Urban Traffic Emergency Detection Based on IoT

设计了基于物联网的智能交通网络公路交通突发事件自动检测方法。利用物联网技术的优势,以交通突发事件所具有的特征研究为基础,以交通突发事件本身特征作为主要检测对象,进行有针对性的城市道路信息的采集,并使用免疫算法作为采集信息的数据融合方法,根据融合后的数据来对交通突发事件进行判定。实验表明,利用物联网平台并配合免疫算法,无论是检测率还是误报率都有比较大的改善,并且对于未知的突发事件也有较好的支持,是一种非常有效的城市交通突发事件检测方法。

An automatic urban road traffic emergency detection approach based on IoT technology was developed.Ta-king the advantage of the IoT technology and using the characteristics of urban traffic emergency itself as the main detection object,the targeted information on city roads are gathered and fused together with immune algorithm,therefore the traffic emergency can be predicated by using these fused data.Experiment results indicate that proposed method can obtain an improvement on detection rate and error rate,and also the unknown emergency can be better supported,thus demonstrating the effectiveness of the presented method in this paper.
