The purpose of this study is to examine a method of traffic congestion data collection using scanned high resolution panchromatic imagery acquired from satellite. The existing traffic monitoring systems including manual and automatic vehicle recording technologies have several limitations in terms of accuracy and spatial coverage ranges. In this paper, traffic information is achieved by frequency analysis techniques from the segmented bridge and/or road images. Especially, the study simulated digital images by fast Fourier transform (FFT) and applied the technique to different two cases in terms of un-clustered vehicles and clustered vehicles
