THE REAL TIME ESTIMATION OF ORIGIN-DESTINATION MATRICES FOR FREEWAY COORIDORS

This paper examines the estimation of Origin-Destination (OD) matrices for freeway corridors using time series of traffic counts. The use of inner link volumes rather than only input and output volumes is a basic assumption in this paper. To derive expressions for the link- flow variances and covariances a trip generation model is presented that describes the choices of destination of individual vehicles as a random choice process. Since the estimated OD-matrix will be used for prediction purposes, the aim is to estimate the choice probabilities in this model rather than estimating the actual OD-volumes. A Kalman based method is described in which the model-predicted link-flow variances and covariances are used while processing the measurements.
