| Abstract: | A state space model is proposed so that the dynamic OD matrix can be estimated through the surveillance of link flows and traveling times in traffic networks. Moreover, an analytical formula for calculating the assignment matrix which is essential in the proposed model, is presented. With the Kalman filtering method, a real-time recursive OD estimation algorithm is developed and validated by numerical results. |
