This article describes a method for correcting a given OriginDestination (O/D) matrix based on microscopic simulation, using the Simulation of Urban MObility (SUMO) package. Assuming, that the O/D matrix has an error of 5%, an optimization problem is proposed for finding the trips comprising it that best approximate to the measured traffic flows. The process involves computing the user equilibrium on each iteration, using the DUAITERATE algorithm provided in the SUMO package. Simulation results were obtained through simulated annealing, which show the validity of the correction method.
