Intersection flow release prediction method based on acceleration model and short-term trajectory data

The invention discloses an intersection flow release prediction method based on an acceleration model and short-term trajectory data. The intersection flow release prediction method is mainly characterized by comprising the following steps of: quickly constructing an acceleration trajectory of a vehicle near a signalized intersection by fully utilizing the short-term trajectory data and priori knowledge which can be quickly acquired; a driving behavior theory is utilized, travel efficiency and comfort are considered, vehicle acceleration common characteristics are extracted, and multiple types of acceleration models containing a small number of parameters are constructed; the model parameter correction difficulty is changed by utilizing an optimal control theory; acquiring short-term vehicle data by using an intelligent traffic system sensor, selecting the type of the vehicle and correcting parameters for all vehicles at the intersection; all vehicle tracks are generated by utilizing the characteristic that a
