Method for forecasting ultra-short term bus load based on load trend changes

The invention relates to a method for forecasting an ultra-short term bus load based on load trend changes. The method comprises the following steps of: firstly, modeling a bus load; secondly, acquiring and processing bus load sample data; thirdly, selecting similar historical days; and fourthly, forecasting and calculating the ultra-short term bus load. According to the method, the obtaining of the forecasting result of the ultra-short term bus load is accelerated; and compared with the traditional methods, the method has the advantages of simpleness, practicality, high calculation speed, and accurate forecasting result meeting the requirements on real-time scheduling and real-time safe check.
