基于声强的交通流数据采集与状态分析

Analyses of Traffic Flow Data Acquisition and Traffic Condition on the basis of Traffic Sound Intensity

在提取交通声强信号特征的基础上,利用AvantLite动态信号分析系统记录数据,导入基于声强的交通流分析系统,融合路段相邻两点的数据,根据交通量差值比判断该路段的交通状态,为提高交通流检测技术水平提供理论和实践基础。

In this paper, on the basis of the traffic sound intensity signal feature extraction, using AvantLite dynamic signal analysis system and recording the data. Then importing the data to the traffic noise analysis system, and integrating two sections＇s traffic data value to analyze the traffic condition according to the traffic volume differential, to provide the theoretical basis and practical basis to improve the detection technology level of traffic flow.
