摘要
车流密度是研究交通流理的重要参数之一。小波变换是近年来兴起的一种信号分析工具 ,它可以将信号进行多分辨分析。本文将小波变换应用于车流信号的分析 ,从而更好地分析它的概貌与局部细节。
The traffic density is one of the most important parameters in the traffic research. Wavelet Transform is a new signal analysis tool in recent years, to make multi-resolution analysis of the signals. In this paper the traffic signal is analyzed with its Wavelet Transform so as to watch the approximation and details more accurately.
