Microscopic traffic simulations are useful for solving various traffic- related problems, e.g. traffic jams and accidents, local and global environmental and energy problems, maintaining mobility in aging societies, and evacuation plan- ning for natural as well as man-made disasters. The origin-destination (OD) matrix is often used as the input to represent traffic demands into traffic simulators. In this study, we propose an indirect method for estimating the OD matrix using a traffic simulator as an internal model. The proposed method is designed to output results that are consistent with the input of the simulator. The method consists of the following steps: (1) calculating link traffic volume from the OD matrix, and (2) updating the matrix. The estimated matrix is updated iteratively until it converges to a predefined tolerance level. Numerical experiments are then conducted using the proposed method on a grid network and on a representation of an actual road network. Finally, we discuss the characteristics of the proposed method and the non-negative constraint for the traffic volume.
