Abstract

Road travel time and its forecasting value are the important bases of urban traffic management and traffic information service,and they are also an important reference for travelers to choose their reasonable traveling routes.In this paper,first,a calculation algorithm and a preprocessing method of urban travel time data are presented.Then,the status of the baseline drift in road travel time series is analyzed,and a method to correct the baseline drift is put forward by utilizing the wavelet analysis method,so as to reduce the noise of travel time series.Finally,a road travel time forecasting model is constructed based on the auto-regressive and moving average ( ARMA) model,and it is proved to be valid and accurate by using actual data.

Key words： floating car; travel time forecasting; baseline drift; wavelet analysis; auto-regressive and moving average model
