GPS-based traffic running tendency prediction method

The invention provides a GPS-based traffic running tendency prediction method, which takes a GPS device as a technological base, and achieves the prediction of traffic running tendency through analyzing intermediate parameters of traffic running index variation. The GPS-based traffic running tendency prediction method comprises the steps of: calculating a period average speed of road sections by using GPS data; judging traffic congestion state of a single road section; calculating period road network traffic running indexes; calculating a series of intermediate parameters of traffic running index variation; determining a state of traffic running tendency; and predicting the traffic running tendency.
