The invention discloses a road traffic flow statistical method and system. The system comprises a data acquisition module, a sequence construction module, a data processing module, a weight determination module, a weight fusion module and a data fusion module. The data acquisition module acquires road traffic flow data through various different types of traffic flow detection systems. Then the sequence construction module counts the local expectation and variance of the traffic flow data of each road, and constructs a detection data sequence based on the calculated local expectation and variance; and the data processing module adopts a quartile method to eliminate abnormal data in a detection data sequence, so that the detection precision is improved. The weight determination module determines an expected weight and a variance weight corresponding to the traffic flow data of each road through the detection data sequence. And the weight fusion module fuses the expected weight and the variance weight to determine a comprehensive weight corresponding to the traffic flow data of each road. The data fusion module fuses the road traffic flow data based on the comprehensive weight, and further improves the precision of the road traffic flow data.
本发明公开了一种道路车流量统计方法及系统,包括数据获取模块、序列构建模块、数据处理模块、权重确定模块、权重融合模块和数据融合模块组成。数据获取模块先通过多种不同类型的车流量检测系统采集道路车流量数据。然后序列构建模块统计出各道路车流量数据的局部期望和方差,并基于计算出的局部期望和方差构建起检测数据序列。数据处理模块采用四分位数法剔除检测数据序列中的异常数据,提高检测精度。权重确定模块通过检测数据序列确定各道路车流量数据对应的期望权重和方差权重。权重融合模块融合期望权重和方差权重以确定各道路车流量数据对应的综合权重。数据融合模块基于综合权重将各道路车流量数据融合,进一步提高道路车流量数据的精度。
