Study on the Estimation of the Origin-Destination Matrix

The estimation of the O-D matrixes is an essential data source of traffic planning, management and control of the transportation system. Based on the review of the literature, in this paper, the present of the research of the O-D matrixes estimation for road transportation system are summarized and remarked. It involved the research on the number and rationality of traffic detector layout project and the methodologies about the estimation of the static O-D matrix and dynamic O-D estimation are summarized. At last, the key issues of the field are given.
