The investigative costs of traditional method have increased with the increase in population and vehicles. Because Intelligent Transportation Systems developed and falling costs, it is possible that seting vehicle detectors intensively to obtain all link flow. So that a lot of estimated O-D trip models from link flows such as least squares method, the bi-level programming method, the path flow estimation, conditional inverse matrix are proposed. Conditional inverse matrix in the application can meet the practice network, but exist estimate path flow solution are negative situations and the O-D solution are not unique, leading to poor accuracy of estimation result. This paper presents a column exchange method to solve the problem of negative path flow by convert infeasible path based variable to nonbasic variableof ,and using route proportion method to obtain the unique solution, let the estimation of O-D trip demands are more accurately.
