The invention discloses a short-time traffic flow prediction method based on integrated evaluation. Undetermined evaluation indexes are acquired via research and analysis and combination of actual traffic flow prediction scenes; historical data of the undetermined evaluation indexes are acquired so that a historical database is obtained; a historical data matrix based on the historical database is constructed via data preprocessing; main evaluation indexes are obtained via screening by calculating correlation coefficient of all the undetermined evaluation indexes and traffic flow, and respective contribution weight values of the main evaluation indexes are calculated; traffic flow prediction values under all the main evaluation indexes are obtained via combination of real-time traffic flow data and analysis on the traffic flow historical data in the historical database via an improved time sequence similarity measurement method; and traffic flow is predicted by adopting a linear weighed integrated evaluation method according to the obtained traffic flow prediction values under all the main evaluation indexes. Multidimensional time sequences are integrated by the method so that more accurate numerical value prediction results are obtained.
