Study on the characteristics of travel time based on the method of wavelet decomposition

The fixed-point detectors using the technology of Automatic Vehicle Identification (AVI) is able to gather samples of vehicles' travel time on the corresponding section of urban main roads. Through the application of wavelet decomposition method, the irregular travel time data of the road section would be denoised into travel-time curves. These curves would be classified and analyzed to reveal the characteristics and the regular pattern of vehicles' travel time on certain urban road section in order to identify its relationship with land use and urban space distribution.
