The invention provides a travel space-time analysis method based on taxi GPS data map matching. Original taxi GPS data are extracted and pretreatment on the data is carried out; historical data are analyzed, a taxi GPS positioning error accumulation distribution mode is determined, and a secondary buffer region searching method is constructed; taxi travel data are extracted and a positioning point is matched to a road by combining a taxi GPS data direction element and a distance element map establishment matching method; and a travel space distribution feature identification method is established and a travel space-time distribution feature is analyzed by using the matched taxi GPS data. According to the invention, the taxi GPS positioning error distribution feature is analyzed by using massive historical data fully; a taxi GPS positioning point matching efficiency is improved by constructing the secondary buffer region searching method; and a travel distribution effect can be identified and analyzed effectively by using the established distribution feature identification method. The method has the great significance in improving the taxi map matching effect, floating vehicle information collection, and a travel space-time analysis effect and a data support can be provided for the city traffic planning.
