Review of the Short-term Traffic Flow Forecasting Based on the Non-parametric Regression
Qian Haifeng · Journal of Transportation Engineering and Information · 2008
Short-term traffic flow forecasting is one of the key problems of traffic control and traffic flow guidance.Having reviewed the short-term traffic flow forecasting methods based on non-parametric regression,some shortages,for example,weather environment is not considered as a component of state vector,etc.,were pointed out.Some improved methods,such as the data organization method based on the dynamic cluster and decision tree,the state vector based on the space-time and weather environment,and the K mechanism based on the dense degree and state vector,were proposed.Then,the forecasting precision could be improved by the above research,and this supplied a foundation for traffic control and traffic flow guidance.
