The invention discloses an intelligent traffic management system based on big data, and relates to the technical field of traffic management.The intelligent traffic management system adopts a Hash function, in the data acquisition stage, the system obtains personal driving tracks and driver behavior traffic data, the Hash function converts original data into a Hash value with a fixed length, and the Hash value is stored in a database; according to the method, sensitive information cannot be directly associated with specific individuals, time sequence analysis and an ARIMA model are used for predicting future traffic flow, a clustering algorithm and principal component analysis are used for identifying congestion reasons, DBSCAN is adopted for clustering analysis to identify congested road sections, and in a road improvement module, spatio-temporal data mining and trajectory analysis are used for further identifying the congested road sections. And the optimal road improvement scheme is searched through the genetic algorithm, so that the traffic smoothness is further improved, the congestion phenomenon is reduced, and the road planning is further optimized to realize more intelligent and efficient traffic management and service.
本发明公开了一种基于大数据的智慧交通管理系统,涉及交通管理技术领域,本发明采用哈希函数,在数据采集阶段,系统获取了个人行驶轨迹和司机行为交通数据,哈希函数将原始数据转换为固定长度的哈希值,使得敏感信息无法直接关联到具体个体,使用时间序列分析、ARIMA模型预测未来交通流量,利用聚类算法、主成分分析识别拥堵原因,并采用DBSCAN进行聚类分析以识别拥堵路段,在道路改进模块中,使用时空数据挖掘和轨迹分析来进一步识别拥堵路段,并通过遗传算法寻找最优道路改进方案,进一步提高交通流畅性,减少拥堵现象,并进一步优化道路规划,以实现更智慧高效的交通管理和服务。
