【摘要】 利用数据挖掘技术,通过对历史数据的分析预测下一个时间间隔的交通流状况,可以为交通流诱导和信息发布打下基础;通过对路口流量历史数据的聚类分析可得出单路口TOD控制算法的最优时段分段和各时段中的最优控制参数,从而优化单路口控制算法的控制效果;通过对路段流量历史数据之间的关联分析,可得出路段之间的关联规则,从而可以由一个路段的流量推断其关联路段的流量,为实时交通流诱导和信息发布提供实时依据。更多还原

【Abstract】 The prediction of traffic flow at the next time interval based on the analysis of historic data and the application of data mining technology is of great help in traffic division and information distribution.The optimal time distribution by TOD control algorithm at single junctions and the optimal control parameters can be obtained by cluster analysis of historical data at intersections,and in this case,the control algorithm can be optimized.Correlation rules can be drawn by correlation analysis of historical data for traffic at different road sections,and hence the traffic of correlated road sections can be estimated by specific traffic at a known section.Such an estimation can provide references for the real-time traffic division and information distribution.更多还原
