| Abstract: | Given the fact that dynamic OD matrix is difficult to get in ITS research,this paper reviews the evolution process of the theory of dynamic OD matrix estimation.Furthermore,this paper summarizes four key issues in the research:choice of state variables,system equation,relation between OD and traffic counts of road link,and dynamic characteristic of OD matrix.Based on the analysis of these key issues,the paper puts forward the method for the solution,and lays a foundation for further research of the theory. |
