Recognition for change-point of traffic flow binary linear regressions based on projective transform method
Xiaoyuan Wang · Journal of Computer Applications · 2010
The previous researches mainly focused on traffic flow state recognition in advance(namely traffic flow forecasting) and real-time recognition(namely incident detection or traffic flow breakdown detection),but recognition of quantitative change rule of traffic flow was neglected in some degree.Based on the traffic flow theory and the elements of projective transform in descriptive geometry,the key to the change-point recognition was analyzed by the complanation of dualistic linear regression.This method is calibrated and tested on the field data of a road to verify the validity and the feasibility of the theory.
