Microscopic traffic simulations are useful for solving various traffic-related problems. An origindestination (OD) matrix is a typical representation form of traffic demands that is required for simulation. We have been proposed an indirect method to estimate the OD matrix using a traffic simulator as an internal model. However, due to shortage of complete real data, such as signals, estimated results often makes unrealistic traffic congestion in the simulaton. In this study, we introduce constraints to the optimization problem by comparing demand flow and performance flow. Through the experiments most of the unrealistic congestion cases are mitigated.
