Abstract

In this paper a Generalized Least Square estimator for the simultaneous path choice model parameters calibration and Origin-Destination (O-D) matrix estimation is presented. The paper will assume as available information a set of link traffic counts, a starting estimate of the unknown parameters and of the O-D travel demand vector. The problem is formulated as fixed-point model (equilibrium programming) assuming the congested network case, the variability of both O-D demand vector and the matrix of link choice probabilities. Along the paper, the theoretical aspects of the proposed estimator as well as numerical results of numerical applications are described.
