It is essential and compulsory raw data for transportation planning and traffic management. With the traffic parameters collected from vehicle detector(VD), only information of the production ends can be recorded, but the trip attraction of the dynamic O-D matrices however can not be identified simultaneously. Recently, with the helps of the Electronic Toll Collection(ETC) system operation, we could obtain the ETC dynamic O-D by integrating information of origin and destination from the on board unit(OBU). However, the overall dynamic O-D matrix of the toll way remains unsolved with this limited information. This research regards the volume of trip production and the ETC O-D matrix as observation information, and unknown O-D trip table as the state variables. Then we can develop brand new system model to solve this problem. Employing adaptuve Kalman filter algorithm, the dynamic O-D matrix can be estimated. Finally, the simulation simple case will illustrate the whole algorithm process.
