Abstract:
Based on an available parking space occupancy(APSO)survey conducted in Nanjing, China, an APSO forecasting model is proposed.The APSO survey results indicate that the time series of APSO with different time-sections are periodical and self-similar, and the fluctuation of the APSO increases with the decrease in time-sections.Taking the short-time change behavior into account, an APSO forecasting model combined wavelet analysis and a weighted Markov chain is presented.In this model, an original APSO time series is first decomposed by wavelet analysis, and the results include low frequency signals representing the basic trends of APSO and several high frequency signals representing disturbances of the APSO.Then different Markov models are used to forecast the changes of low and high frequency signals, respectively.Finally, integrating the predicted results induces the final forecasted APSO.A case study verifies the applicability of the proposed model.The comparisons between measured and forecasted results show that the model is a competent model and its accuracy relies on real-time update of the APSO database.
